We were very pleased with the work of Corey Burr and Stephanie McGovern. We visited a number of loacations and ultimately settled on a very specific location in Chevy Chase.

The entrire process was made substantially easier by their compatability, efficiency, and professionalism.

Christopher Hagan
Anne was constantly aware of the requirements we had for a house and was very flexible in assisting us.

She really went the extra mile.
Bert K.
Angela was very attentive to our needs. She was responsive to our questions and went about and beyond to show properties to us.

My husband & I have moved 5 times in the last 12 years. Obviously, we've dealt with many realtors both on the buying and selling side. I have to say that Sarah Vassiliou is by far the BEST realtor we've ever worked with. Her professionalism, personality, attention to detail, responsiveness, and ability to close the deal was outstanding! If you are buying or selling a home, do yourselves a favor and hire Sarah!
Leah Hepburn
Angela Neeb helped us find a rental in less than a week. She was incredible to work with and I’d recommend her to anyone looking to rent or buy a home!

Stephanie has been an incredible asset in our search for a home. We started out looking for rental home to get to know the area, but had limited time to come to DC to look for properties. Stephanie vetted several places for us and did a video walk-through of the home we ultimately rented. We could not have done it without her! She has been attentive and responsive throughout our home-buying process. We highly recommend her without reservation to anyone looking for a new home in the DMV!

Jacqui & Matt Kilivris
Alexandra is the best realtor a first-time homebuyer could have. She is sincerely attentive, provides thorough responses, and prompt with recommendations and suggestions. As a buyer who considers the potential of each house methodically, Alexandra works with my pace. She does not offer superficial statements like "this is your dream house!" I would recommend Alexandra to anyone looking for a realtor who provides professionalism, graciousness, and integrity!

O. Yu
We highly recommend Alexandra to anyone who wants an honest, aggressive, diligent, and results-driven realtor. Her actions prove she cares and wants the very best for you. Alexandra went above and beyond countless times on our behalf. Save your time and go with the very best the first time around with Alexandra.

With Alexandra’s help we ended up buying what we hope is our forever home. Thanks Alexandra!

I would highly recommend Alexandra to any of our friends and would not blink in using her again in the future.
Summer & Gary Seaward
Anne is an outstanding agent. The Burr Group is fortunate to have her!
Dr. Lakshman
The Burr Group, and my agent Mary Alice Swengros, went above and beyond to prepare my mother’s house for what turned out to be a very quick sale. In addition, they set up all the administrative tasks and the signing seamlessly thereby requiring a minimal effort on my part. All areas of the company were professional and very knowledgeable. I highly recommend them!
Iana Bohmer
Anne was very helpful with our transaction. We had to communicate via phoe, email, and mail; not an easy or normal deal. We are appreciative of her assistance during the process. 

Joseph Torrisi
Corey is highly knowledgeable and very professional. He was able to analyze the market efficiently to develop a pricing strategy that sold the house before the property was listed. Looking forward to working with him again on our next development project. We would highly recommend Corey for all of your real estate needs.
Bob Saah
Thank you Angela Neeb for assisting me in my very specific home search in Bethesda, Maryland. Angela was ALWAYS available for home tours and typically I was the first to view a property.  She helped me figure out the best way to position an offer and what price to go in at to give the absolute best chance an offer would be accepted, no small feat in this market. After viewing many properties, I eventually found (and bought with Angela's help) the place I was looking for in the small community I really wanted to live in, where only one to two places lists a year at most.
Renee Swift
Corey and his Burr Group team provide great service. He is as knowledgeable as any residential broker in the area, providing the best advice and tirelessly working on your behalf. I highly recommend him, whether buying or selling your home. 
Carter Steuart
Angela Neeb is a top-of-the-line realtor. She is very knowledgeable, thoroughly professional, and truly cares about helping buyers find the right home and navigate a difficult process. She listens well, communicates clearly, responds with lightning speed, and is incredibly patient with her explanations. I cannot imagine a better realtor. I give her the highest possible marks and strongest recommendation.
Mary Wertsch
Corey was an incredible asset for usin our first home buying process. We greatly appreciated his vast knowledge of the industry and expertise within the greater DC market. We would highly recommend Corey to anyone looking to buy or sell their home. 
Kevin Keegan
You will not find a better realtor than Corey Burr. His years of experience, strong connections to the D.C. community and beyond, outstanding communication skills, and excellent judgment combine to make him an invaluable asset when buying or selling a home. Corey skillfully guided us through a year of preparation for our home sale, giving us excellent advice all along the way. The result was that our home sold during the first weekend on the market with five competing offers all over the asking price. He is even-tempered and unflappable. He handles even the most challenging issues easily and competently. On top of all of this, he is a kind and polite gentleman, and it's a pleasure to be around him. We can't recommend Corey highly enough - he deserves 50 stars! 
Anne Walker
I'm glad to recommend realtor Alexandra Bryk. Alex came to me via recommendation, and I hired her to sell my property. I was pleased with the process and the outcome.  Alex is very easy to deal with and is great at explaining the reasoning behind making decisions every step of the way. Her easy manner would be particularly good for first-time homebuyers. Her recommendations for vendors were good and those transactions went smoothly as well. I would hire Alex again for a home sale or purchase.
Larry Contratti
Corey is an exceptional broker who is 100% committed to helping you find the right home. He is always available, and helps guide you through the often stressful homebuying process. He is a consummate professional who always acts in the best interests of his clients.
Scott O'Gorman
We appreciated Angela's advice and experience. Angela was on top of the details and greatly helped us sell our property!
Lance Rice
Angela was a pleasure to work with. She really made selling the property easy with her knowledge. She was on top of everything. I hope to work with her again in the future. 
Brittany Ross
My experience working with Angela was excellent. From our first meeting she was attentive, discreet and clearly skilled. Her professionalism made an urgent situation less stressful and her responsiveness and attention to detail is beyond expectations. I highly recommend having her support on your next relocation.
Elisha Gregg
Angela helped my wife and I find our home, and she also helped my parents buy their home when they moved to the area. In both instances, Angela was amazing, thoughtful, professional, and I don't know how we would have bought a place without her in retrospect, and I am sure we will go back to her for any future real estate representation in the future. Anyone with Angela representing them is beyond lucky, would highly highly highly recommend to anyone else!
Nick Wertsch
Angela made the process of finding a home as stress-free and enjoyable as possible! My partner and I are very appreciative of how responsive she is to our questions on weekdays and weekends and how well connected she is. She connected us to a great lender and Title company, advocated for us on many fronts, scheduled appointments for home viewings for us and was always punctual. She helped us navigate this process to buy a home that was right for us all within one month of searching for a place. Highly recommend Angela to anyone in the area looking for a realtor who cares deeply about her relationship with clients and the quality of her work.
Vignesh Sadras
Angela was very helpful in my girlfriend and I finding an apartment in DC. We relocated from Atlanta and Angela provided helpful information on DC neighborhoods. She listened to our needs and leveraged her network to find appropriate properties for us. On our visits, she came prepared with information on each property and made sure all pertinent questions were asked. We highly recommend Angela for your real estate needs!
