Dr. Grover is a board-certified general surgeon with Focused Practice Distinction in Metabolic and Bariatric Surgery. He is the fellowship director of the Advanced GI MIS/Bariatric Surgery program at Gundersen Health System.  

Dr. Grover graduated from the University of Health Sciences – COM (now known as KCU), in Kansas City, Mo. He completed a surgery residency at Wright State University/Wright Patterson Air Force Base, in Dayton, Ohio.
