Dentistry is a door to many unexpected opportunities. This was certainly the case for Dr. Sam Smiley of Dublin, Ohio. 13 years into his career, Dr. Smiley received a fateful call from the Columbus Zoo. A 350-pound western gorilla was not eating properly and was in obvious distress. Dr. Smiley was asked if he’d perform a dental exam during the gorilla’s routine physical. He agreed, and so began his career as a volunteer dentist for the Columbus Zoo.
