I was seen for significant weight loss, I had a lot medical concerns that other providers I felt had disregarded. Dr. Changizzadeh listened to me, heard my concerns, listened to my pain. Made appropriate referrals. He also left a detailed clinical note for me to review later on. Would recommend him over anyone else.

Rude and obnoxious. He asked me how I was feeling. When I started answering he told me that usually a patient listens while he talks. Basically told me to shut up. It just went downhill from there. He needs a course in manners if he is going to be interacting with people.
