What People Say About Dr. Michael Keller, MD

After being diagnosed with colon cancer I was referred to Dr Keller by Dr Muhammad Ali. Dr. Keller's expertise and professionalism is the reason I'm alive today. A Robotic Sigmoid Colectomy was performed through small incisions. After the procedure I never suffered much pain and I recovered quickly. I would recommend Dr. Keller to my family and friends.
