Dr. Goondi is great. The office staff is very professional. My ezcema and allergies have cleared up since I began coming here.

I have been a patient of Dr. Kletz and Dr. Gondi for 2+ years now, and they have taken excellent care of me and my complex medical issues! I am immunocompromised with a variety of allergy/upper respiratory issues, and they always ensure I am clear on what to do to manage my symptoms and starting shots was a game changer after being a life long allergy sufferer. The nurses and front desk staff are lovely and make sure that patients feel welcome, and I even enjoy seeing the "regulars" around the office when we are all there for shots! Especially in the changing COVID-19 environment, they have been transparent and helpful to patients. If you are an allergy or asthma sufferer, they will take care of you!

Probably the best allergists in the Washington Metro Area. Before Kletz took care of me, I used to see Dr. Black. They are both excellent. Staff is exceptional.
