Patient Reviews
Apr 26, 2026
Dr. Andrew De Mar was excellent. I had internal scar tissue that had wrapped around my small intestine. He located my problem via x-ray and performed successful laparoscopic surgery. He kept me informed and relaxed through the process. He is very knowledgeable; answered my questions; professional attitude; excellent surgeon. He has a great team of surgical doctors and nurses. I'm glad he was my surgeon.
