James Boyle
Medical Coordinator

James Boyle received his bachelor’s degree in science from St. John’s University in New York. He holds his Physician Assistant degree from Bayley Seton in Staten Island, New York. He completed a postgraduate surgical residency at St Vincent’s Medical Center. He has been a Denver resident and colleague of Dr. Douglas A. Dennis for more than ten years.

As the Medical Coordinator for Operation Walk Denver, James puts in many hours painstakingly planning for each mission. James first accompanied Dr. Dennis on a mission trip with the Operation Walk California team. The experience profoundly changed his life. According to James, “the smile and hug I receive after taking care of a patient on an Operation Walk Mission trip can be equated to the smile and hug I receive after putting a band aid on my three-year-old daughter’s bruise. Pure, sincere appreciation.”
