Dr. Bollman and Flint Hill Surgery Clinic
I just had surgery on 7/28 with Dr.Hachem at Flint Hills Surgical, and I have been SO impressed by him and the staff. (it's a big deal that I'm impressed, becasue I am a picky nurse myself.) I don't know as much about Dr. Bollman, but that he has been doing bariatric surgery for a LONG time, so I know he is very experienced. His son used to work there also, and did my friends RNY, and she has done fantastic with her surgery.
I had Dr. Bollman do my surgery and I can't say enough great things about him and his staff. My mother is a nurse and was very impressed by him as well. He even gave out his home number to call if I had problems right after surgery. I had to call him at home over the weekend one time and he was great. I think he really does go that extra mile and I have never felt rushed in my appointments with him - either with all my questions before surgery or after. I would highly recommend him.
