Johann  had a sleeve with Dr C and says “Surgery had many beneficial health impacts including diabetes reversal,reduced arthritic pain and swelling and led to a beautiful baby after 12 years of trying”


Caren Chandler, a Dr C patient says “Dr C is very approachable and very experienced and he changed my life”

Caren Chandler

Dr C is a very professional and skilled surgeon. I felt like I was in safe hands for my entire hospital visit. In addition to the multitude of tests they do pre-op, to make sure you’re healthy enough for surgery, they explain everything thoroughly. I had no complications afterwards and was happy with the tool I had been given. I would recommend either Dr C or Dr H to anyone who is thinking of getting wls. Their cv and reviews from patients speak volumes about how knowledgeable and professional they both are in this area of surgery. I had a revision surgery with Dr H, to help fix a reflux problem. He is very kind and has an excellent bedside manner. I have had no complications from my surgery with him either. I’m happy with my decision and would make the same choice 100 times over. With either surgeon, you will be in safe and professional hands, who have performed this surgery thousands of times.
