What People Say About Dr. John Clarke III, MD
Reply
I met with Dr Clarke for an early morning for which he was 90 minutes late. He glanced at some case notes and stated that he would schedule my procedures “as soon as possible.” After a week of silence from his office I called to get an update. I’m now scheduled to have the procedures done ... 6 weeks from our consultation. He typifies an employed physician.The least impressive interaction I have had with a physician..
