What People Say About Us

"Genevieve Concannon and her associate, Theresa Twifold, demonstrated outstanding knowledge of the local real estate market in Arlington County.  They were quick to realize the value of our property in terms of land development when others had given up on  that possibility. Their perception of local government land development possibilities for our property resulted in a sale at a value beyond all expectation. The sale progressed as predicted, with approval to sub-divide, contacts with known developers, and an “in-house” sale at our asking price which saved time, and money on the sales commission. We are very, very happy with the over-all outcome."

- John W. Moorleghen 2/17

"Working with Theresa was a wonderful experience. She was patient, knowledgeable, and extremely thorough as a buyers agent. She showed us 15+ homes in Alexandria and Arlington. When we requested to view some homes in DC proper she even went so far as to link us up with another realtor more familiar   with the area so that we would have the best service and experience possible! She recommended local lender and title agencies and helped set up appointments with contractors for quotes during inspections. We were moving from out of state when we settled on a home in Alexandria and Theresa was phenomenal in helping us close from afar and made several trips back to the house to ensure the sellers complied with agreements and looked out for our general interests. Can't thank her enough and highly recommend her!"

-B. West 7/17

"Christine lives in the area of her expertise, the advantage of which is evident in her local knowledge. She prepared us well for the buying process--despite our less-than-conventional situation--and responded quickly to our questions, suggestions, requests, and when a few quirks (not of her doing)   cropped up late in the game. Christine is objective, fair, provides candid and reasonable advice, and creative in her ability to get to "yes." Simply put, she was a joy to work with and made sure we walked away feeling great about our new dream home!"

-Wagget 7/17

"My experience with the home buying process is there is a lot of waiting. The waiting on hearing from offers, the appraisal inspection, loan underwriters, etc. This was not the case with Jeremy. He was always very quick to respond and was excellent explaining every part of the process as well as defining things I didn't understand right away. I know who I will be using if I need an agent again."

– Jared Felty, Washington, DC

"Genevieve is such a wonderful realtor. She is extremely attentive, quite knowledgeable of the area, and willing to work with us even though our time difference is 8 hours. Highly recommend Genevieve to anyone looking in VA for their next home. "

-J. Chao 6/17

"Genevieve was wonderful to work with when buying our first home! She was very professional, experienced, organized, positive, and prompt. She was thorough and attentive, making sure that we knew everything that was needed to buy our first home. I was amazed at Genevieve’s knowledge and expertise   through each step of the process. She made wonderful recommendations for inspectors, lenders, and etc . We are very happy with our home and appreciate all her help! I would highly recommend Genevieve and her team of experts! We would love to work with her again when we are ready to move on to our next home!"

-S. Spicer 6/17

"Christine did a LOT of prework and had properties lined up for us to see on Friday when we drove down to meet her (we are out of state), and set aside 3 hours to view them. Well, that three hours turned into most of Friday afternoon/evening as well as Saturday and a little bit of Sunday. By the time we left Sunday, our daughter had a place lined up and we had a new friend in Christine! To top it off Christine stopped by a week after the move in to see how things were going, which is service above and beyond our expectations. She does not just want to close a deal, she wants to make sure the deal is right for you. Christine is highly recommended, do yourself a favor and contact her for your real estate needs."

"Genevieve Concannon exceeds expectations! She pairs her professionalism with an endearing sense of community to Northern Virginia - a well-balanced achievement of meeting her clients’ needs and encouraging and guiding them through the home buying process. Genevieve supported my family to buy our  first home. She began by hearing our vision for our future and presented properties within our budget that met that vision, always considering what was important to us in a home. Then as we began visiting potential homes she taught us so much about home-buying through her years of experience and connections. As the process for putting offers on homes began, she was reliable, quick to respond to our questions, and efficient with other realtors. When our offer was accepted, she was with us every step of the way explaining contract obligations, supporting our lender, and celebrating with us as closing. Genevieve walked through an important phase in our lives with us, and we felt well taken care of and supported by her remarkable warmth, effectiveness, and experience. When my friends and colleagues who rent ask how buying a first home was, we say how fun and rewarding it was to go through it with Genevieve! We highly recommend Genevieve and her team at Advon Real Estate to anyone - she is capable to work alongside all types of visionaries, personalities, and families. We consider it a privilege to have bought a home with Genevieve and consider her an ally to any family looking for a one-of-a-kind professional who stands out in her field. We’ve yet to mention that Advon Real Estate holds high standards for equity, social and sustainable responsibility, and quality care for their clients! If you are wondering who to consider for the home buying process, do not waste your time looking further. With Genevieve you are not just a client, you are part of the #AdvonFamily. You are treated with the utmost respect, care, support and kindness in every step of the process towards home ownership!"

- J Burgin 4/17

Thank you so much for being a part of our house hunting experience. Not only did we obtain our beautiful dream house but also a lifelong friendship with you that I will cherish forever. We could not have asked for a more thorough and knowledgable realtor. Your assuredness and work ethic made this process extremely efficient for us. Both Dammun and I look forward to making new memories and friends at Chapel Square...."

- Yvonne P.

"We found Genevieve through Zillow and knew nothing about her, but we couldn't have asked for anyone better to assist in our home buying experience! She was really friendly from our first meeting, and was honest, upfront, and helpful throughout the entire process. Even when we had hiccups during our  process, she walked us through it and did whatever she could to make it as painless as possible. Whenever we had questions she was quick to respond and made things easy to understand for us first-time home buyers. We highly recommend anyone who is looking for a home to contact Genevieve, she won't disappoint!"

- Linda GK

“Jeremy Dalpiaz was perfect, very attentive, very professional, and always would go out of his way to help during any stage of my home purchasing process. As a first-time home buyer he always answered any questions day or night and was always available and prepared. I did not hesitate to take any suggestions or recommendations Jeremy offered. Jeremy understood from day one what my requirements/limitations were for my growing family. Even when some of the stages were at a standstill, Jeremy would send a message to reassure that everything was going smoothly or give constant updates which were very helpful. Jeremy's a very strong negotiator and would give his idea of what outcomes would've been in my best interests but always left it up to me in the end so I never felt pressured into any situation. I would HIGHLY recommend Jeremy Dalpiaz. He has made this first home buying experience a breeze, even with the slight bumps in the road!”

- Ryan Miller, Ashburn

"It was indeed a huge blessing to have come across Genevieve Concannon via google search being my 1st home purchase and no idea about the process. She was very responsive and within a couple of minutes, she reached out to me via text and we were able to setup our 1st meeting. I find her to be  approachable, committed and dedicated, detail oriented, down to heart, friendly, very knowledgeable about the buying process and above all looks out for the best interest of her clients. She never missed any meeting that pertained to my home and would always take notes to keep us both informed. If I have to do it again, I will go through Genevieve Concannon of Advon Real Estate."

"Theresa knows the Falls Church market inside and out. She found us a home and sold our home in the span of about 6 weeks and we weren't even looking to move. That is a sign of a good realtor!"

-Annie T

  “Jeremy Dalpiaz is a professional negotiator, an extremely attentive realtor, and all around fun person to work with.  He sold my investment condo in 2 short months at a great price.  He knew what color scheme to paint to draw wide interest and he understood the intricacies of finding just the right buyer. Jeremy clearly knows the real estate business.  The process was complicated as DC law requires special considerations with sales involving pre-existing tenants, but Jeremy researched the rules and complied with all the requirements on my behalf. He made the process as easy as it can be. And where there were challenges he really stepped up to protect my interests. I couldn't be happier with the service I received from Jeremy.”

- Rachel Khalili, Washington, D.C.

"I had a long list of objectives that I didn't think would be possible to pull together in one location. Genevieve never gave up and we found the perfect new home. Not only is she exceptionally knowledgeable and talented as a real estate agent, she is a blast to hang out with. Once we found the  house, Genevieve's negotiation skills were exceptional. She helped us work through various issues and brought both sides together. The dogs and I are moving into our new home tomorrow thanks to Genevieve. Oh yeah, I can't forget the rest of her transition team. They have been great. I'm using several of their trusted recommendations for improvements and services."

- J Wilmot 6/16

"Christine is an amazing real estate agent and made this daunting process a very enjoyable experience. I am a first time buyer and was looking for a place while living out of state. She did so much work on my behalf and was completely attuned to my needs and the many suggestions of my parents. As a novice there are so many questions and concerns and I wanted everyones input on the process. She was so patient and understanding of all my doubts. She lives in the area and is personally invested in the neighborhoods she shows. This gives her a much better understanding of the people and place I was looking to become a part of. Christine is kind, patient and thoroughly invested in her clients happiness. I was so lucky to find her. I look forward to buying my next home with her as well."


"When we began looking for a real estate agent, we came across Genevieve on account of her amazing reviews. After working with her to sell our condo, I totally understand why everyone has such great things to say about her. She is highly knowledgeable about the real estate market, super responsive to questions/concerns, extremely organized, and just generally a great person to interact with. Genevieve managed to get us three full-ask offers within 48 hours of our first showing! We will definitely be coming back to her for our next home purchase. If you are in search of an incredibly talented real estate agent, you can stop looking: you've found her."

- K. Sholes

"As a first time home buyer and a single mom on a limited budget, I had some trepidations about moving forward in purchasing a home for my family. I feel so lucky to have found Genevieve! She is extremely knowledgable about the area, the value of properties, and the facts you need to know when  looking at a new home. There is quite a bit more to consider then just the aesthetic qualities and Gen was quick to share her knowledge about the different properties. She was patient and very easy to work with. She is very flexible with the time she offers to her clients and goes well out of her way to make sure she is meeting your needs. With so much new information to learn, she does a great job explaining everything in understandable language...which as a teacher I can truly appreciate! I felt like she was really looking out for my best interests throughout the entire process and even after closing she didn't hesitate to help me out with some post-move in issues. I thought that was an amazing feature of her services! Her team that handles the paperwork behind the scenes was also very helpful and easy to work with. I completely recommend Gen as the guide in purchasing your new home!!"

"I was deployed for a year in Afghanistan when I found out that we would be reassigned to the DC area. Theresa listen to our needs and helped us narrow our search. I only had two days of my mid-tour leave to find a house. She cleared her scheduled, showed us 8 properties in the area we targeted via email, and we had decided on a home within a day, under contract within a week, and closed two months later. Theresa was all over every detail throughout the whole process. She took a huge stresser from our lives and assisted us in buying a great home in a prime location! I have bought eight homes over 17 years and this was the smoothest experience. She has all my future business, and I recommend her to everyone I come across that is heading to DC."

- Lee and Kim

"Genevieve, as our listing agent was quite simply the best - super enthusiastic, professional, and market savvy.  Since our home was in need of renovations we elected not to make, she worked with us to come up with the right price for listing our house "as is."  As a result, it sold quickly yet  comfortably above our bottom line.  I highly recommend her as your listing or selling agent (although as our listing agent, she ending up being the only agent, which our purchasers were comfortable with).  Whether you retain Genevieve as buying or listing agent, you won't regret it. She will work diligently for, and with, you to get the best result possible."

-G Younger 1/17

"Where do I begin? Working with Genevieve was the best decision we ever made. As first time home buyers, Genevieve made this process a breeze. Her thoroughness and attention to detail was second to none. She explained everything clearly throughout the whole process and made sure we were always fully  informed. We recommend that anyone looking to purchase a home reaches out to Geneveive. She is an absolute joy to work with and with without a doubt will be our choice for all real estate needs in the future. 5 Stars!!!!"

-R Gordon 7/17

"Working with Genevieve was an absolute dream. She is the epitome of a professional and her knowledge of the Northern Virginia market is downright impressive. When I contacted her to sell my house, she had data on my specific market back to me within hours. It helped me price my house right (and   WAAAAY higher than I thought it could be!). All correspondence after that was darn-near immediate and everyone in her office was obviously on the top of their game. She had good relationships with a number of other vendors who helped us get our house ready to sell. She even let us use some of her own artwork to stage our home. Unbelievable! After the house sold (in only 4 days, might I add), she and her team were ON TOP OF EVERYTHING. They made sure the buyers fulfilled all of their obligations and stuck to the agreed upon timelines. When anything came up, Gen handled it and kept me informed of the progress. I couldn't have asked for a smoother process. Go with Advon!!! You'll be so pleased!"

-S. Cook 6/17

“We were first time homebuyers, full of naive questions and uncertainty. Jeremy did a great job guiding us through the process, keeping our spirits up in a tough market, and getting us into a fantastic house at a great price.”

– Amanda Butler and Soren Dayton, Washington, D.C.

Working with Genevieve was an easy and painless process! I had a deployed husband and in my 3rd trimester of pregnancy, dealing with VA loans, legal documents and house hunting, Genevieve was patient, understand, and knowledgeable throughout the entire home buying process. She was objective when needed to be but provided her expert opinion when solicited, which I found the most helpful being a first-time home buyer. Thanks to Genevieve, it was a smooth experience and I would recommend her to anyone looking for a home in the Northern Virginia market!

- L. Ospina

“In 2015, my best friend and I decided that we wanted a bigger and nicer place to live. We contacted Jeremy Dalpiaz about this and within 24 hours he had six places for us to check out. He spent all day with us taking us from place to place. We happened to find the perfect property that day. Though it was a little high in price he talked the price down for us. Then after a long day he still sat down and did all the paper work. Best experience I've ever had finding a new place to live.”

– Brian Klonarides, Ashburn, VA
