Patient Reviews
Apr 17, 2026
No greeting would not allow questions and never ever looked at me in the eye nor allowed one question or comment about my health by me. Looked straight down the whole appt. Typing not conversing with me at all, except to say no guestions, I let you ask questions at the very end. When he was through typing which took the whole visit. He still had never looked up at me. I do not know how he could have been typing anything about me as he would not allow conversing. For all I know he was answering someone else’s email. His behavior is probably the rudest uncaring doctor in my close to 70 years of seeing doctors I have ever found. I have never left a bad review about another doctor. This was quite the example of he needs some reprimand from his current group. When he typed last button, literally just jumped off stool and flung open the door and went out. No time for that question or 2 and don’t try to be an advocate for yourself he isn’t having it. Gotta go! Next patient!
