Dr. William Campion joined Performance’s Warren location as a physical therapist in 2018. Dr. Campion earned his Bachelor’s degree in Criminal Justice in 2005 and his Doctor of Physical Therapy in 2011 both from Utica College. In 2010 he completed the United Cerebral Palsy Strength & Conditioning 7-week pilot program in Utica, NY. Dr. Campion then went on to complete the Medical Personnel training at Marine Corps Marathon in Washington, D.C. and the Red Cross Emergency Medical Responder both in 2013. Dr. Campion had the opportunity to volunteer for United Cerebral Palsy in 2010 to help develop strengthening and agility exercises for children with cerebral palsy. In 2014, Dr. Campion became a certified USA Weightlifting Olympic Lifting Coach level 1, (CFSC) Certified Functional Strength Coach through Mike Boyle in 2015, USA Power Lifting Certified Lifting Coach Level 1 in 2016, and Rock Blade IASTM Certified 2018. With his training, Dr. Campion has gone on to specialize in sports performance, orthopedics, post-surgical, gait/running analysis, footwear, custom inserts/ orthotics, Olympic lifting, power lifting, cross fit, golf, and functional movement. Dr. Campion began working in a running specialty store in high school and became an avid runner while finishing up his undergraduate degree in criminal justice. After working as in an investigator for the district attorney's office for 2 years, Dr. Campion realized he wanted to pursue a career in fitness since it had become such a huge part of his life over the years. While working at the running store he learned how to analyze gait analysis and became familiar with foot and ankle biomechanics which helped him through multiple basketball injuries. All this training pushed him towards pursuing a career in physical therapy to help expand his knowledge in this area to help other athletes battle their injuries. When he’s not in the clinic, you can catch Dr. Campion sailing, running, hiking, lifting, playing basketball, brewing beer, cooking, and hanging out with his lovely wife and 2 handsome dogs.
