She is an amazing physician. She listens, she explains, she follows up and she really cares. I felt invisible for so long because my health concerns weren’t being heard until i found her!

Dr. Ameli is the very best doctor my husband and I haven EVER had. He is thorough, comprehensive, knows what he talks about, and his referrals are excellent. He is a good listener. He is okay if you disagree with him, but he will just tell you what he thinks. His follow-up on issues is excellent, and that is helped by his extremely functional office and staff. His/staff’s response time is very good and prscriptions are renewed very quickly.
