Dr. Schlenker has participated in other various sports including football, basketball, wrestling, track/field, and triathlon. Currently Dr. Schlenker is an avid runner and has participated in several long distance relay races including Hood to Coast, Rainier to Pacific and Cascade Lakes.

His experience and interest in sports has led Dr. Schlenker to specialize in this specific area of medicine. While his goal is to prevent sports related injuries, Dr. Schlenker’s unique approach emphasizes patient participation and ultimately decreases overall recovery time.
