Dr. Kletz is a knowledgeable, personable doctor who believes his patients. I have had nothing but a good experience at his office. It is true that the wifi doesn't work and prescriptions are written out rather than transmitted electronically, but honestly it's really not that much of a hassle as there's cell signal in the waiting room.

Came in for my 4 year old with moderate eczema to be seen and Dr.Kletz was unprofessional to a degree. I had to ask for the door to be closed while being seen by the doctor which was a major turn off. He started asking questions, talking and attempting to carrying on with the appointment while people traffic walked by the open door. As well he didn’t have a healthy relationship with the staff/nurses at least during the time I was there, from what I saw. This was my first time being seen by him and this practice in general and either he was very confident in providing only one cream option (expensive, multiple applications during the day and needed to be on for a year at minimum according to him) for help with controlling the eczema or was motivated to complete the appointment early. No allergy testing was recommended or other diagnostic options. Only one option without conversation with me about what will work best for my family given our current lifestyle and financial situation. We’ve been challenged with my daughters eczema since her birth so we’ve been through our share of allergist and dermatologist. Anywho I wouldn’t recommend this place primarily because of the lack of professionalism and slightly outdated system of handling files (all paper no online system). We visited the dc office

Highly recommend! Dr. Kletz, all of the nurses, and all of the folks at the front desk are fantastic! I started coming here almost two years ago, and in that time, I have seen a significant improvement in my allergies. I’m no longer allergic to dogs, and I no longer suffer from seasonal allergies. Dr. Kletz also helped me with my asthma symptoms. I’m so glad I found this practice!
