About Greg DeFilippo

Greg graduated with a Bachelor’s degree in Biology from the University of Notre Dame in 1989. His interest in warmer climates and the desire to avoid life in a microbiology lab led him to the University of Florida, where he completed a Master’s degree in Exercise Physiology in 1991. As a Gator, he went on to complete their Physical Therapy Program in 1993. While at the University of Florida, Greg was a Graduate Assistant in the Center for Exercise Science with a focus on the development of cervical, thoracic, and lumbar spinal strength utilizing equipment designed by MedX. His master’s thesis was titled the “Effect of Training Frequency on Cervical Rotation Strength.”

Once he completed his Physical Therapy degree, he had the opportunity to continue the research on a more clinical basis in San Diego, CA, at the UCSD Spine and Joint Conditioning Center. Greg had the honor of working with both Vert Mooney, MD, and Leonard Matheson, PhD, as part of a team performing research involving MedX Spinal Strengthening and Functional Capacity Evaluations. He worked with the group of MDs, PhDs, Chiropractors, PTs, PTAs, ATCs, and Exercise Physiologists in an outpatient clinic developing the clinical protocols that continue to be utilized in the clinics today at East Tennessee Spine & Sport. The spinal protocols evolved into a measurement driven phase system, with an emphasis on the transition from the movement directed care of the McKenzie Method to the isolated strengthening produced by MedX spine equipment.

Greg is certified in MedX Spinal Strengthening, the Cal FCP for Functional Capacity Evaluation, and Mechanical Diagnosis and Therapy (The McKenzie Method). He has also served as an instructor during certification courses involving both MedX and the Cal FCP. He has spoken at several conferences on topics such as the MDRS Clinical Phase System, the use of MedX protocols, and the use of PTAs, ATCs, and EP’s in the physical therapy clinic.

Greg was part of a group of clinicians who formed a company focused on promoting these protocols and the development of outpatient physical therapy clinics. The company was called Measurement Driven Rehabilitation Systems (MDRS). In 1995, Greg was asked to move to Knoxville to develop a location in East Tennessee. Although he spent several years traveling to and from California to help develop numerous clinics, Tennessee became his home. He is now the sole owner of East Tennessee Spine & Sport, dedicating all of his time to the continued development of our local network of clinics.

Greg is the father of three incredible young women. Although he struggles at times with their choice of schools, he is very proud of his two Tennessee Volunteers and his one Kentucky Wildcat. He enjoys hanging out with his daughters when they let him, which is always more enjoyable when that includes sports, some sun, and (of course) fishing.
