Testimonials about Dr. Ahn

Mrs. Smitherton

Dr. Ahn has been my allergist for at least four years now, and I continue to return to him because I trust him. He listens to me, and is open, friendly, relaxed and confident, and makes constant eye contact with me. He has offered me courses of treatment for my allergies that I chose not to take, because I chose to use acupuncture or a naturopath, and he was open and accepting of my choices without being pushy or denigrating natural medicine.

Mr. Johnston

I don’t know what I would have done had I not found Dr. Ahn. I have repeated swelling attacks of my lips and tongue and face and no other doctor knew what was going on. Dr. Ahn told me I had angioedema and started treatment for it. I can’t thank him enough.
