Born and raised in Glendale, Aaron McGuinness is the founder and owner of Aspire Physical Therapy & Sports Performance. He specializes in orthopedic and sports physical therapy. He received his Bachelor of Science Degree from Gonzaga University, where he was a 4-year starting shortstop on the Bulldog baseball team. He completed his Doctorate in Physical Therapy from the University of Southern California in 2011 and was accepted into the university’s residency program, where he completed his Orthopedic Certified Specialist in 2011.

Aaron worked closely with many sports physicians, including a Dodger physician, Dr. John Itamura, the USC sports physician Dr. George Hatch, and the Lakers physician Dr. Dan Kharrazi with Kerlan and Jobe Orthopedics. Aaron works with a wide array of athletes, from adolescent to professional, by developing sport specific exercises, injury prevention programs, post-operative protocols, and strengthening programs to return to the prior level of function.

Aaron’s Vision: “I want to help athletes of all ages perform at the peak level with strength and body mechanics that will promote the athlete’s maximum ability while preventing injury. Many athletes are unaware of their faulty movement patterns and risk for injury until it is too late, and that’s where we can help. With proper training, treatment, and motivation, the athlete can get the most out of themselves. And remember, we are all athletes in our own way, so this approach is appropriate for all patient types.”
