Patient Reviews
May 24, 2024
The absolute best doctor I’ve ever been to. Hands down, Dr. Unger found the diagnosis that others had missed. He’s brilliant at his craft and has the attention to detail that others lack. He was with me for my appointment for over an hour. I never once felt rushed or that he was inconvenienced. You can see the respect, love and admiration Dr. Unger has for his patients. I actually look forward to my follow up appointments with him. His staff is remarkable too, not the typical nurses that seem to hate their job, you see the opposite here at his office. How lucky are we as his patients! I know I’m in the best hands.
