Dr mark is a good doctor but with my family’s history of cancer I wanted to do a colonoscopy at only eight years since the last one he did we had problems with the insurance which I don’t understand because it was supposed to be 100% free and they sent me an estimate of $580. Patient responsibility at that point I had to cancel don’t know why.or if they coded it right or the price of the colonoscopy is more than the insurance covers not sure, but we had to cancel
