“She was so patient and kind, very professional and helped me through everything in a clear and concise way.”

“Dr. Hummer spent about an hour with me, as opposed to my last psychiatrist, who spent at most ten minutes with me. She asked me a lot of pertinent questions, which helped her decide how best to help me. She listened to me and took note of what I said. She made a number of changes in my medication, which I welcomed. I found her to be kind and empathetic, which my last psychiatrist was definitely not. I am very impressed by Dr. Hummer.”
