MEET THE Medici PHYSICAL THERAPY Team
Our team's 40 years of combined experience and their dedication to each individual patient's condition and recovery is what sets us apart from other local physical therapy clinics:
Bill Tjaden - Physical Therapist
Bill brings a wealth of knowledge and career experience to his practice of physical therapy. He has been a practitioner for 21 years since graduating from the University of Nebraska Medical Center in 2000.
The first 10 years of his career were spent as the senior therapist and clinical education coordinator for Endurance Rehabilitation in Scottsdale, Arizona. Here he practiced sports medicine, learned and practiced myofascial release, prescribed and fit custom orthotics, and treated patients from recreational to professional in all major sports.
Bill also was the Senior Manager of Physical Therapy for Barrow Neurosurgical Associates in Phoenix Arizona which was at the time the largest neurosurgical firm in the world. He developed their physical therapy practice, hired, and managed staff to care for the most challenging orthopedic spine cases for this prestigious practice.
It was at these two jobs that Bill began to clearly see and develop a practice model for the body as a whole.
Moving to Atlanta in 2012, Bill sought to learn more about treating the body from a holistic perspective. While working for an outpatient physical therapy practice, he became a certified colonic hydrotherapist, kinesiologist, and began practicing craniosacral therapy.
In 2019, Bill joined Medici Spine & Pain and brings his unique whole-body practice philosophy to the state-of-the art Medici rehabilitation facility.
