Dr. Hornbostel received his medical degree from the University of Southern California in Los Angeles and received his surgery training at the University of Missouri – Kansas City School of Medicine. In 2002, he performed the first laparoscopic gastric bypass surgery between St. Louis and Denver.

“I’m interested in things like diabetes and high blood pressure and sleep apnea and cholesterol issues,” says Dr. Hornbostel. “We know that bariatric surgery is the best treatment for all of those problems.”
