- KBKolin BehrensMay 21, 20261.0I’m very disappointed by this provider. I was referred by my primary care physician for some food intolerances, and Dr. Kletz provided no answers despite it being listed as a specialty of this clinic. Additionally, when I booked this appointment, I was told over the phone that this provider was in network, and was not told anything different when in the office, but received a phone call almost a week later that, surprise surprise, they were actually now out of network and would be charging me the full amount. I would not recommend anyone trust this sub-par office to help them or be honest about their billing practices.
- TMTyler McCoyJan 31, 20235.0I have been going to the DC office for a few years now and always have had a good experience. The staff is professional and kind. Additionally, I have never had any issues with billing, insurance, etc. Highly recommend.
- MSMJ SmithMay 23, 20195.0Highly 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!
- DKDani KarnoffFeb 6, 20195.0Dr. Gondi is an extremely kind and considerate doctor. He is very takes his time with his patients and doesn't rush through appointments. The staff is also extremely accommodating and willing to help. I would highly recommend this practice!
