He was exceptionally professional and genuine. It’s important to trust your physician and I do. He at no point made mefeel stupid or inadequate when I expressed my concerns. I would highly recommend him. Both the staff and he were just phenomenal. By far one of the best physicians I’ve had.

Dr. Ackert is amazing! He took the time to listen to me carefully and explained every single possible diagnosis and how it could be treated. He has a very positive atitude about feeling and getting better. He's caring and warm. Itold him he would have been a great psychiatrist! Even with so many years of experience, he shows the excitement of a newly medical school graduate who is ready to save the world! I'm feeling very confident he'll help me feel better. Thank you Dr. Ackert!

I would never recommend Dr. Ackert to anyone. He did three things that were highly unacceptable: 1. He ordered a procedure to be done prior to consulting lab tests results. 2. He asked me if I had HIV in a verycondescending way. "Are you an HIV person?" This is extremely offensive to people suffering from this disease. 3. He misread another order of lab results and did not correct himself until I asked for a physical copy two weeks later.
