I have been coming to Dr. Hadjiev for the last 6 years and I have found him and his staff to be very helpful and thorough. Even through both my pregnancies, he was very knowledgeable with what I could take and when and how much. I highly recommend all the staff to help out with your needs.
I always feel I am in good hands and my allergies are in the best hands. I never have any concerns and I like how they listen to any concerns I have or might not agree with certain things.

I have been coming to Dr. Hadjiev for the last 6 years and I have to say that he is absolutely wonderful. I also really enjoy PA Epstein as well ~ they are very thorough and take their time to make sure that I understand what I am doing with my medication. I highly recommend them to anyone.

Fabulous caring, compassionate, knowledgeable doctor. Takes the time to explain everything in a calm, comfortable manner. He made me feel confident that my many allergies can be controlled and I will be able to breathe easily once again! I feel happy to have found him and needless to say recommend him highly.

I had a great visit and a great follow up

I suffer from severe inflammation and JRA. I break out in hives when I eat nightshades, especially tomatoes and eggplant. I went to Dr Hadjiev to see what other nightshades I may be allergic to. He did a skin prk test, and I had a horrible reaction to everything; rash, swollen throat, sweating, dizziness. He concluded that I have Zero allergies. Needless to say, I am in the hands of a much more compassionate and qualified doctor to treat my symptoms, and ultimately get to the root of the problem
