Treasurer-Elect: Francisco Valencia, MD

Francisco Valencia, MDI, Dr. Francisco Valencia, had the great fortune of being born and raised in Nogales, Arizona, a small town on the U.S.-Mexico border. This environment instilled in me an appreciation for multiculturalism. However, it was a twist of fate that as a teenager I met an American orthopedic surgeon who was volunteering at St. Andrew’s Children’s Clinic, a non-profit clinic serving indigent Mexican children with physical disabilities. This sparked my interest in orthopedics and, specifically, children with disabilities. After completing my pediatric orthopedic fellowship at the Children’s Hospital in San Diego, I returned to southern Arizona, initially as a full-time faculty member at the University of Arizona. For the last 20 years, I have run a successful private practice in Tucson, Arizona.

I have thoroughly enjoyed being a member of the AACPDM and have developed great professional and personal relationships through participation in various academic and service roles. I have had the pleasure to have been a member of the International Affairs and Education Committees and honored to serve as chair for both. I served on the Nominating Committee once, the Strategic Planning Committee twice, and the Scientific Committee three times. I am the Scientific Committee co-chair for the 2019 annual meeting.

I have had the opportunity to volunteer and participate in educational programs in Asia, Africa, Europe, and South and North America. However, I am most proud of my over forty years of ongoing monthly volunteer work at St. Andrew’s Children’s Clinic in Nogales, Arizona.

My wife, Marty, and I have been married for 26 years and have two daughters and one puppy!
