• An Alabama resident since childhood, Dr. Stahl attended Auburn University where he graduated with highest honors and a BS in biology. He received his M.D. degree from The University of Alabama at Birmingham School of Medicine, and completed his internship and surgery residency at Carraway Methodist Medical Center in Birmingham. He entered private practice in 1994, ultimately forming Cahaba Valley Surgical Group, and practiced a full range of general surgery including gastrointestinal, breast, thyroid, and parathyroid diseases. However, he gradually focused most of his attention on bariatric surgery. Initially performing the open gastric bypass procedure, Dr. Stahl was one of only a few surgeons in the state offering this operation. Following the footsteps of Drs. Henry Laws and Ronnie Clements, Dr. Stahl became one of the first Alabama surgeons to offer laparoscopic gastric bypass. As his bariatric practice grew, so did his interest in weight loss surgery and the metabolic effects of such surgery. Recruited from private practice and into academic medicine, he joined the faculty at UAB in 2010 as the medical director of bariatric surgery.

    Dr. Stahl is married to Dr. Elizabeth Stahl, an endocrinologist, and has three children.
