What People Say About Dr. Sam Ahn, MD
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.

×Post a ResponseAre you Dr. Sam Ahn, MD?
I've always had great experiences with Dr. Ahn and his office staff. Dr. Ahn spends plenty of time with his patients, which helps make the visit more personal. He always listens to my concerns and answers any questions I have. I feel like he goes above and beyond for his patients. I have been going to his Warner office for ~2 years and I wouldn't consider going anywhere else for my allergy or asthma needs.
