My overall experience was imprecise. I do not recommend David L Longworth, MD (Internal Medicine) if you have a serious health issue. Getting an appointment with this doctor was easy and convenient. The waiting time was less than five minutes. The staff at Cleveland Clinic were professional and well mannered. He did not take the time to go over my vitals and symptoms. Also, he was not clear and or hands on. He kept say " You look fine. The medicine should start working in a few weeks." I was not fine and I became more ill.
