Dr Ackert is now my go-to and I feel really lucky to have been told about him. He listens carefully and is a thoughtful diagnostician, but also has a lovely bedside manner. He explains clearly what's going on and his ideas for ongoing treatment. Highly recommend!

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.

Dr. Ackert was very professional, kind and thorough in his explanation of the colonoscopy procedure. He really took the time to talk to me like a person without looking at his computer instead of me. He did my first colonoscopy 10years ago and I remember that he and his staff were wonderful!
