Dr. Kalfa was comprehensive and accommodating. He performed allergy testing, prescribed/recommended some medication, and initiated immunotherapy for the long-term treatment of my allergies. I'm looking forward to working with him in the future.
October 8, 2024Stuart H.Verified patient
I would definitely recommend! I have been sick for a few years and no one has taken the time to really dig into what is causing and keeping me sick. I felt like the office really listened to everything I had to say and is taking all possible measures to diagnose and treat me. I am glad I ended up going here.
August 22, 2024Cassandra D.Verified patient
Dr. Kalfa was very thorough and patient. He explained everything clearly and answered all of my questions as we discussed treatment options. The allergy test was fast and painless and it brought much needed clarity to my symptoms. Would highly recommend this clinic to anybody!

I highly recommend Dr. Vasif Kalfa. He is a great listener and has an incredible ability to put you at ease. I recently experienced anaphylaxis and almost died so my anxiety level is through the roof. Dr. Kalfa carefully reviewed medical history, asked lots of questions, listened intently to my responses. He reassured me I could go back to resuming a normal lifestyle. Of course, I have to battle my phobias to overcome my mental state of remaining stuck in the same old patterns.
December 12, 2023Clinton S.Verified patient

Doctor was through and professional. He cured my allergies after a examination in his office. It took about a week to lesson my cough and sneezing spells but he did it, so far.

Kind, knowledgeable doctor. Assistant was nice as well. Front office staff were unfriendly. I was greeted with "Are you SURE you have an appointment?" I almost left before seeing the doctor. Overall good experience but the receptionists/schedulers need to be friendlier.
