I entered into the corporate profession of real estate long before becoming a Realtor with a strong desire to help others navigate the complicated processes of buying or selling a home through real estate law firm work. I realize that for many, a home is often the most expensive purchase he/she/they will make in life.  I am empathetic with the stresses of preparing a residence for sale and work very hard to minimize the difficulties inherent in the process.

My clients are my priority, and because I have been a Realtor in agency now for 15 years, it's my experience of 27 years in real estate that has guided me in fulfilling  my clients' expectations.  They are to assist them with everything about their home sale or purchase and my goal.  I will ensure that negotiations are sound and straightforward, and I am obligated to seamless transaction coordination with honesty, integrity and professionalism being of the utmost importance to me. 

A strong suit of mine, based on years of successful home sales and an inherent intuition or gift, is that of prepping a home with advice to my clients on my listings as well as personally staging the home to appeal to the potential buyer pool.  My clients have been so pleased, and this is a service I provide at no additional charge . . . unless furniture has to be brought in.  Whether you need contract negotiation advice, staging assistance before you sell or me to list your home . . . my background is strong and unique.

" Mary was a huge help in guiding us through the process of purchasing our first home. As first-time home buyers, we had lots of questions and she was very knowledgeable about the area, and extremely responsive to our needs. She went above and beyond to assist us in finding our dream first home. We couldn't be happier! Thank you so much, Mary!"

– Sarah Jesensky

" Wow! Such a great experience we had working with Mary Roberge on the sale of our home in Leesburg, VA. From our first consult with Mary where she detailed the present real estate market conditions, detailed thoughts on our home, and what comparable homes were out there, to our settlement day, Mary was on top of everything! Our decision to sell was a quick one and happened just a couple of weeks before our long time planned 2 week vacation abroad. Mary quickly showed up after our initial call to discuss our home, it’s condition and marketability, and walked through each room detailing things that may help market the house. She was not just focused on pricing, it was all of the other things to help stage and prepare the house to go to market to bring us the best possible offers. After walking through each room and giving us recommendations, she also provided us a check list of recommended things we could do to help with the sale. This was all a huge help to have that guidance based on her many years in the real estate business. As previously mentioned, we had just two weeks from our first meeting to our target date to “list” the house as we were leaving for vacation. No problem for Mary. She jumped right in with a list of contractors who could help in any and all of the areas we needed assistance completing or simply just having a licensed professional doing the work. Indeed the close relationships she has developed with these businesses helped us tremendously as Mary called them to grease the skids given our short timeline to have them come out on such short notice to help. Each of the contractors and businesses she referred to us were great to work with including plumbers, electricians, painters, movers, power washers, etc. Finally, our prep and staging work was completed and the sign went in our yard the Friday night before leaving for vacation the next day. Long story short, all of the prep and advice paid off. We had an excellent offer on our home in just 3 short days. Since we were out of the country at the time, Mary stayed on top everything as things were moving quickly. She communicated with us via calls, texts, and email. The purchasers wanted a quick turnaround and asked to have all inspections completed in short order (home, well, water quality, pool, pest, septic) and wanted to settle in just three weeks time from offer. While we were very happy with the offer occurring so quickly, it made us very nervous that we still had 1.5 weeks of vacation left and would not be at home to facilitate all of the inspections and to pack up a 5500 square foot home with 17 years of accumulated “things.” No problem for Mary. She assured us we could get this done and she jumped right in to help with the buyers and getting all the inspections completed and providing us status on which was occurring and when, as well as the results. Meanwhile, she put us on to her contact at a local moving company who we could tee up to help with packing and moving our household items upon our return. In the end, everything worked out perfectly for us and we know we were very fortunate. Indeed there may have been some good fortune involved, but certainly, we had the good fortune of working with Mary who greatly advised, coordinated, and reassured us throughout the process. Settlement occurred without issue and was quick and painless (again due to using Mary’s recommended settlement agent). We could not be happier. Thank you very much Mary!!! "

" Mary was outstanding to work with. From beginning to end, she was patient and made the home selling process incredibly simple which was huge for first-time sellers as my wife and I were. Mary was particularly astute when it came to preparing and staging our home to get the most attention and attract solid offers almost immediately after the listing hit the market. I recommend her as a valuable partner for buying or selling in the competitive Northern Virginia market."

– Sean Yarborough

" Mary expertly guided us through the sale of our home. She prompted us to get the house listed at the perfect time in the market. All of her staging tips were spot-on for getting the house ready for showing. To our surprise and delight, we got an offer the very first day the house was listed! Mary helped us navigate the contract process and all of the inspections. From the beginning to closing, she made the process simple and seamless. Mary is a consummate professional and is absolutely wonderful to work with. Thank you, Mary! "

– Diana and Scott Waterman

" We decided to sell our home in Fairfax and purchase a brand new home in Ashburn, Virginia. We are both Deaf and pondered whether to select a realtor who knows the American Sign Language (ASL) or a realtor who could communicate with us using paper/pencil or the iPhone/iPad using speech to text. After interviewing four different realtors, we almost gave up hope but decided to try once more after reading the wealth reviews about Mary Roberge on her website as well as on Zillow. We sent an email informing her we are Deaf and would like to interview her to determine whether she could represent us well in both the sellers and buyers market. On the day of the interview, she brought with her a sign language interpreter. From the get-go, we never regretted our decision. Mary knows the market backward and forwards and is familiar with every nook and cranny of the neighborhoods. Working with Mary Roberge exceeded any of our expectations. Right away she was incredibly friendly and took time to sit down with us. She was very helpful in explaining the entire process and really relieved our stress level even though we were on a very tight timeframe. When it was time to sell our home, she gave us recommendations for a lender, painter, kitchen and master bath renovators all of whom were way better than the people we found on our own. She monitored all of the work process making sure our home was ready for the market. When it was time to put our home on the market, we had many interested buyers. We sold our home and were happy that it was so fast. She is all about integrity and excellence. Extremely detailed and patient and on top of all this, she is such a kind soul. We believe this is a great attribute and shows she is not just interested in a quick sale. She took great care of us as we bought a new home, through all the thick and thin of it, she tirelessly walked us thru the process, helping us to navigate thru tricky negotiations and a down-to-the-wire closing. We are very fortunate to have found her and truly believe her expertise helped tremendously in both selling and buying our new home. The main reason we give Mary a 5 star, is that she treats you like her one and only client. Your concerns are her concerns, and she works incredibly hard and has a lot of experience to make things go smoothly and the way that you want. Emails and texts calls are answered very quickly and thoroughly - you will never be left wondering what is happening. In short, if you are buying your first home or a 2nd or 3rd home, you can’t go wrong with Mary. She was so helpful with providing help in every way, and she exceeded all of our expectations. If we get the chance again in the near future to put our home on the market, we will go with Mary Roberge. Thank you, Mary! "

" "If you are looking to buy or sell a home, I would highly recommend Mary Roberge as a wonderful agent. I used Mary for both services last year, and my experience was excellent. Mary is exceedingly knowledgeable about the real estate market, is very savvy about marketing a home, and she goes the extra mile in terms of making her clients feel comfortable and well represented. She's enthusiastic, persistent, and is simply a pleasure to deal with. She is also an expert negotiator. She sold my home more quickly than expected and at an excellent price. I couldn't have been more pleased. I can recommend her without hesitation." "

– K. Spak

" To whom it may concern, I am writing to comment on my long time relationship with Mary Roberge. I have known Mary since the late 1980’s from her days in the title business, and have watched her evolve to have a successful career in real estate. There are several things that have always struck me as unique about Mary. First is that she truly cares about the people she works with. And this statement probably appears to have less value since it has become cliché, thanks to every single realtor stating on their website, business cards and marketing pieces that they “really care about their clients and always put them first.” The sad truth is that most realtors put themselves first, and have turned caring about the client into a tired cliché. Thanks to a quarter century of exposure to watching how Mary interfaces with her clients I can report that she truthfully does put her clients and other parties she interfaces with first. Mary is also unique in that she has a super human energy level. In all the time I have known her I have never seen her lacking drive, enthusiasm, a proactive train of thought or the desire to get things done to achieve the necessary results. She has the drive to get things done. Mary also has knowledge and comfort in all levels of business transactions, from small dollar value to high end transactions. Last, I would say an important asset of Mary’s is how she connects to people. At the end of the day after all the technology, websites, search engine optimization, lead generation and marketing campaigns; this is still a business of people choosing to work with other people. Mary is likable, friendly, and comes across as trustworthy. That is what people want to choose when they are looking for someone to work for, or to work with. I would never hesitate to refer Mary to a homeowner, as a team leader, for a business opportunity, or to a friend who simply wants someone to talk to. Mary delivers at all levels. Please contact me with any questions."

– Brian Martucci

" Mary is a first class Agent that was a delight to work with. Her guidance in all aspects of our home selling process was invaluable. She knows her craft extremely well and is an absolute professional for staging, pricing, and selling our home quickly. Hard working while maintaining the highest standards of integrity, she is an outstanding representative for the real estate profession. We would not hesitate to list with her again and she is a five star performer across all of your evaluation criteria."

– Bill and Karen B.

" I was referred to Mary after I was unable to get my house sold under another agent (after 3 months on the market over the summer). Mary was able to immediately diagnose the issues, properly assess the value, and market it effectively. After relisting our house with Mary in the off-season, we received a competitive offer and Mary helped negotiate the sale to keep as much money in our pocket as possible. She was extremely helpful in scheduling and completing any repairs required due to inspection results and coordinated the closing while we were out of state. She was always very responsive, knowledgeable, and I highly recommend her to get your house sold!"

– Kerry S.

" Working with Mary was a great experience from start to finish. First, she is very knowledgeable with regard to the local real estate market. Second, she is very responsive to inquiries. In addition, she will provide you with candid and informative feedback. I highly recommend her."

– Jim and Laura

" My family and I were fortunate to work with Mary in selling our home after relocating to Atlanta. My company relocation program gave us an option of a couple of good realtors who prepared a market analysis and a marketing plan. After being introduced to Mary through a family friend we had her prepare an analysis for us as well. People often say the proof is in the pudding, well I’m here to say the proof is in the real work that realtors do. It was clear comparing the three agents that Mary’s work product, local knowledge and aggressive marketing plan was superior. Mary stood out head and shoulders above the competition and we chose her to be our agent. It was the best decision we ever made. She gave us such outstanding personal attention, which was needed as we tried to sell a house from 700 miles away. She went above and beyond by recommending resources for key landscaping, handyman, and other services to maintain the property and keep it in top shape. This was in addition to proactively holding open houses, broker days, and the effective use of online and social media marketing. Our house sold at our asking price and Mary delivered the voluminous paperwork that was required through my firm’s relocation agent without a hitch. She was a godsend. I would ABSOLUTELY use Mary again and I would highly recommend her for anyone who wants to buy and sell real estate in the Washington DC metro area."

– R. Pettiford

" Mary Roberge is as good as it gets. She has assisted me with the sale of two homes. The first home she sold in two weeks, despite the fact that the Housing Market was at a standstill. Everyone was telling me that my house would be on the market for four months. If you are serious about selling your home, Mary Roberge is the Realtor that you need. She knows the business inside out. I would recommend her to everyone who seeks to sell their home. She is the best."

– D. Gregory

" Buying or selling a home, you will not be disappointed with Mary Roberge and the white glove, high touch quality of service she will provide to you. Mary has excellent communications skills and knowledge of the market. Don't make a "move" without Mary!"

– Sylvia Pocs

" Mary assisted us with the sale of our primary residence in Leesburg Virginia and a rental property in Frederick Maryland. Mary's guidance on preparing the properties for buyer presentation was both realistic and focused on the areas that mattered most. Mary worked diligently within her real estate network to pre-stage our properties and raise awareness in the market. She was present for all showings, which was important to my husband and me, and her expertise was valuable in the negotiation process. Both of our properties had offers within days of being put on the market and sold much faster than we had expected! We have (and continue to) recommended Mary to friends and associates and enthusiastically recommend her to anyone looking for a knowledgeable and conscientious agent to assist with the sale of their home."

– Stephanie Skipper

" I have known Mary for quite a few years and she is not only a consummate professional, but a genuine person. I have trusted her with many real estate referrals only to be thanked by them for her great service. Mary makes it a point to know her community and the areas she serves to better her knowledge base for her clients."

– Ingrid Teasdale

" “Mary made the stressful process of buying a home very easy and smooth for us. Her knowledge of real estate is vast and she is very detail-oriented. She was readily available whenever we had any questions. She puts her clients’ needs first and is a pleasure to work with. Thanks Mary.” Chandra"

– Chandra

" Thank you for all the hard work, time and effort you put forth the past 4 months in helping me find the home that met "all" my requirements. Price, location, view ( golf, river and woods) ... and of course, the "Donald Trump" negotiating skills you demonstrated to meet the selling price I was looking for at (removed for privacy). The trifecta! . . . . You were a true professional and answered every call and responded with detailed emails to all my questions- and I truly appreciate your patience, support and counsel. . . . Your energy, passion, knowledge in the real estate market, attention to detail, and empathy is something that I recognize and truly appreciate. . . . I will absolutely recommend you to all friends and contacts looking for a property. You are a superstar! Kerry in Ashburn, VA"

– Kerry in Ashburn (Listing and Purchase)

" Mary was a joy to work with! I have to say that she went above and beyond her responsibilities when she took on our home after we relocated. We decided to do a lot of improvements from new tile in the kitchen and baths, granite counters, cooktop & sink in the kitchen, paint, carpets and landscaping. I was not able to stay to see that the work was completed but she joyfully took on the task of letting contractors in and out, referred some contractors to us that she had worked with before, put a rush on the photography of our home for the ad (so that we could quickly get the house on the market) and called almost everyday to keep us up to date. Plus this was all being done the week before Christmas to add to the stress, yet she was never flustered and did everything with a smile. Because of her help we were able to get our house under contract only six days after putting it on the market and closed 4 weeks later and got 97% of our asking price! You can’t ask for more than that!!"

– Bev and Randy

" I highly recommend Mary Roberge as a REALTOR with all the skills and knowledge needed to help you get a great deal in the home you are looking for! Earlier this year Mary Roberge helped us buy our new home near Leesburg. Her extensive knowledge and love of the area, depth of understanding of value, ability at negotiation, and patience while we worked through more than a year of selling our home in California and moving to Virginia really helped us tremendously. Mary helped us look at all the options over a very wide area, helped narrow down to what was not only possible but also reasonable and fit our parameters; overall, a great experience. Cheers, Cynthia "

– Cynthia & Ed

" We purchased our home in Adamstown, Maryland in July, 2012. Mary Roberge was our realtor and we highly recommend her. When we were searching for our home, I was traveling from Delaware with a 2 year old and a 4 year old while my husband was working and staying in Virginia. Mary helped us navigate a stressful and difficult situation from purchasing our home long distance, to scheduling inspections, and handling situations with a challenging finance company. Her knowledge and input helped us find a beautiful home and make it ours. "

– Martha and Eytan

" We had a wonderful experience selling our home with Mary! She was extremely professional, knowledgeable, and available. When we ran into some issues with our tenant, Mary handled them with grace and tact and gave us excellent advice. She has a large network of contacts that she drew upon to help us with the sale, from lawyers to handymen. She is also personable and upbeat--key qualities when you are buying or selling a home. My husband and I highly recommend Mary and would definitely work with her again. Sharon in Ashburn, VA "

– Sharon

" Mary handled all aspects of the process of selling in such a way that most of the tedious details were transparent to my wife and I. Mary's initial activities in providing a market analysis in a very volatile market environment were critical in us to deciding that she was the best candidate to represent us in the sale of our house. From the point of listing the house to the closing, Mary was proactive in anticipating any possible problems and taking actions to handle them. Mary's detailed knowledge of real estate law and processes made the sale of our most valuable asset a worry free transaction. Above and beyond the business expertise that Mary demonstrated is her most valuable asset - her interpersonal skills. Mary is a warm and caring individual and it shows in the care and attention that she provides to her clients. Mary clearly views the relationship aspect with her clients as paramount to her success. In the whole process of selling our home we felt that she went above and beyond the call of duty to keep us informed and reassured that everything was progressing according to plan. I commend your franchise for having a professional like Mary to represent your business. My wife and I would certainly use Mary Roberge to represent us to sell or buy real estate."

– Kevin in Leesburg

" Mary Roberge represented us in the purchase of our new home. Home buying is said to be one of the top ten most stressful events in someone's life. Mary has made things so smooth for us. It has been a stress-free experience. She has taken care of every detail including things we hadn't even thought of yet. Mary is very up-to-date and innovative when in comes to technology. We were buying this home from outside the state of Virginia and she has made us feel like we are right there. We never had to go out of our way to accomplish anything. All communications such as emails and faxes were right on time and always legible. When Mary says she is getting something done, we do not have to worry because it is already taken care of. We can always get in touch with her quickly and she is always ready with the right answer. I'm also amazed at the legal knowledge Mary possesses. She does more than just pull up a contract and start signing it. She knows the ins and outs of how real estate business is conducted and that provided us a very secure feeling. We knew we were in good hands with such an important purchase. We have bought and sold multiple homes before meeting Mary, and I can say that I wish we had met her long ago. I will use her again in the future and would recommend her to all of my family and friends."

– Jeff and Danielle in Ashburn

" My wife and I would like to take this opportunity to express our sincere thanks and appreciation for the fantastic job done by Mary Roberge in the listing, sale and settlement of our home and the subsequent purchase of a new home. In all phases of this transaction Mary was there to make sure everything went as planned and no unforeseen obstacles popped up at the last minute. Not only did she accomplish the listing and sale of our home in a matter of days but she also worked with us to ensure that we would find that special new home. Based on the amount of time she spent with us it seemed as though we were her only clients at the time. We were extremely impressed with her extensive real estate background and knowledge in all aspects of our dealings with her. It was quite evident that she possessed the knowledge and skills to ensure that each phase of the entire process happened as it should. She was able to answer any and all questions we had and more importantly to set our minds at ease as we went through this process. We would be more than happy to use or refer Mary in any real estate transaction we might again go through in the future."

– Everett

" Thanks Mary for all of your great support. I have bought and sold 26 properties and this one has been the most frustrating. You and (ass't) have made this ordeal much easier. . . . You did in 4 months what three previous realtors could not do in 2 years. You did it in a softer market environment also. I just want to make sure I gave you the acknowledgment you deserve. You have done a great job and your personality and attitude is a perfect fit for this job."

– Stewart Bernard

" We want you to know how grateful we were for your ability to listen to our wants and needs, to help us pinpoint the "must have's" in a home, and to find the property that met all of our criteria. Additionally, we were very impressed with your negotiation skills and your ability to get us such a great price on this beautiful home. Your knowledge of our contract, and your ability to recall the details of that contract even months after ratification never ceased to amaze me. It was always so wonderful to be able to call you with a question I had about the contract and to have you give me an answer immediately! Your knowledge of contract law and experience in the legal field was a comfort....We had such a wonderful experience working with you - we would definitely recommend you to anyone interested in buying or selling real estate in Northern Virginia (or Maryland, for that matter)! Thank you, again, for finding our dream home for us."

– Suzanne Ager

" I wanted to tell you how pleased we were with our home Sale, and listing with you . . . . You were completely professional and responsive at every turn. We could not have asked for a better experience. With our unique property you knew just what was needed to get our house sold. We would definitely use your services again."

– Rena and Ned

" A Broker/Owner representing a Purchaser on one of Mary's listings: " . . . . It was a pleasure working with you. I think you did a great job of representing (x) while working towards a transaction that was viable (at one point I thought we were dead). I especially enjoyed sparring with you on market values - you have got to be at least the second best agent (jokingly said!) in Northern Virginia when it comes to property valuation (our discussions - back and forth - were way above comprehension by 98% of all agents). . . . Your 13 page letter was over the top - we all actually read it - you should write a book . . . hope to see you again soon at another table . . . . ""

– A Broker/Owner

" "I have to tell you that you have been so professional, and we really appreciate it. You have truly made an impression on my husband and I, and I wanted to tell you. Thank you." After Mary thanked the Owner, the Owner went on to agree to a 2nd showing of the property by Mary and the potential for Mary to submit a contract on her client's behalf."

– Owner of a property Mary showed

" “ . . . We would not be at this location without you. You promptly answered our first inquiry and continue to help us with the final touches – top notch customer service! We look forward to many happy years ahead.”"
