      Dr. Spadafora serves as a Musculoskeletal Professor in the Doctor of Physical Therapy Program at LMU-Knoxville. His Bachelor of Science was completed in Kinesiology from The University of Tennessee in Knoxville (1994) where he was also a graduate assistant athletic trainer with the football team (1994-96) and became certified in athletic training (1997). His Master’s in Physical Therapy (PT) was completed at Shenandoah University, just outside of Washington, DC (2000). After graduating from PT school, he earned his specialist certification in Orthopedics (2004) and then completed a yearlong manual therapy residency through the Ola Grimsby Institute (2005). He’s always worked as a clinician in outpatient orthopedic settings, and except for one year, in private practice.  Beginning in 2008, he started teaching in the South College Physical Therapy Assistant program, first as an adjunct and then transitioned to full time in 2010 to the present with a goal of bringing more manual therapy, medical exercise prescription, and clinical reasoning into that part of the profession. Additional motivations in teaching include helping students re-frame material and to put information into terms, stories, and experiences that shorten learning curves for greater understanding, familiarity, application, and fun. He also enjoys helping students develop a skill and passion for learning. He continued to practice in the clinic while teaching and started his own turn-key and concierge cash-based clinic in July of 2017. During the fall of the same year he earned a certification in manual physical therapy through the North American Institute of Orthopedic Manual Therapy. His clinical focus and research agenda are on prevention and returning to play for competitive and recreational athletes as well as addressing recalcitrant and persistent conditions of all patients that also need thorough and effective biomechanical investigation and treatment with patient empowerment. Lastly, he completed a terminal Doctoral degree in the Science of Physical Therapy from Andrews University (2020).  Professional memberships include the Tennessee and American Physical Therapy Associations.

      He lives in Knoxville, Tennessee with his wife of more than 20 years, who is a physical therapist in pediatrics, and their three adolescent children. As a family, he enjoys solid movie nights and physically active games as well as getting away to the mountains for hiking, biking, and camping in between supporting his kid’s various and numerous activities. He also likes do-it-yourself projects, especially those involving woodworking, and is big on prevention and staying ahead of things, including with what he eats and high intensity exercise of running, weight training, and swimming. A good nonfiction book as it relates to incredible individuals, the human body, truth, and family are always around as well.
