December 31, 2025Jimmy C.Verified patient
I drove over 2 hrs to see this doctor that ZocDoc said was in my insurance district and the doctor was covered by them. I doubled checked with the office that they were covered by my insurance and they said yes. I waited 40 minutes into my appointment time for this doctor to spend 3 minutes in the room with me. He only looked out over the top of his glasses and said he couldn’t see. I had to ask him to get a light and look with it. He treated me poorly and said to send him pictures of my face when it can be seen. He gave me some samples of cream with NO DIRECTION on how to use them. I went to pick up my prescription, they said he wasn’t in my district or covered by my insurance. So ultimately I was disappointed in many different ways with zocdoc and the doctor. And to top it off I asked for a full body check because I tan and have never seen a dermatologist. They said at another visit because he didn’t have time. That’s because he was running behind an hour! Now I have to start over.
