He recently completed a six-year elected term as a member of the Executive Committee for the American Academy of Pediatrics Council on Sports Medicine and Fitness. Dr. Koutures has also authored over 25 published articles and served as co-editor for the textbook Pediatric Sports Medicine: Essentials for Office Evaluation published by SLACK Incorporated in 2013.

Dr. Christopher Lin grew up in Ohio earning a degree from the Massachusetts Institute of Technology (MIT) with a major in biology and a minor in psychology. He went on to obtain his medical degree from the University of Chicago Pritzker School of Medicine and has been practicing pediatrics for over 20 years. He has also worked in many Urgent Care facilities and in the CHOC emergency department.

Dr. Lin’s family consists of his wife Carol, a pediatric oncology doctor at CHOC, and his twin boys. When not in the office, he spends his free time taking his boys to their soccer games, tennis lessons, and art classes. He also plays tennis, rides bikes with his boys, attends church, and solves Rubix cubes. He loves anything to do with Star Wars, Disney, fantasy football, USA Soccer, and Ohio State University football.

His pediatric philosophy is very simple and straight forward. He treats and advises his patient families as if the children were his own and considers that when making any recommendations.
