Doctor Ackert was very efficient and friendly. Though I was for the appointment and he had a meeting in less than30 minutes, he still spent enough time to proceed the examination and address my concerns. The environment in the clinic was very comfortable.

Dr. Ackert was INCREDIBLY knowledgeable about all of my questions and concerns. He is putting me through a wide series oftests to make sure I get the most informed and holistic care specific to my family history and symptoms of the past few years. I was very pleased to see how thorough he was, and how patient he was with walking me through a "next steps" plan for my health as we get test results in.

He was exceptionally professional and genuine. It’s important to trust your physician and I do. He at no point made me feel 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. I told 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 very condescending 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.
