In 2012, with his right leg effectively useless, Dr. Tait landed back in his practice on a Monday morning to confront reality – that he may need a third surgery on his back. The injury was the result of a 30+ mile, single-day hike for a great cause (and, also from a very stubborn “athlete mind”).

This injury, and the path he found to lead his body back to full strength, without surgery, he believes happened for him, not to him. Without it he would not have discovered the collective power of Functional, Integrative, and Regenerative Medicine to rejuvenate the body and heal the root cause of pain and injuries. His journey became the origin of a philosophic shift in the way he treats orthopedic injuries and pain. This became the launching point for his new practice, Rejuv Medical Southwest.

Almost a decade later, we continue to refine our unique, regenerative and integrative orthopedic procedures. Our proprietary process combines ancient, timeless health best practices with modern, leading-edge technology and lab diagnostics to optimize health effectively and treat the root cause of orthopedic injuries without surgery.

Dr. John Tait - Founder

Chief Health Strategist

Originally from Michigan, since 2010 Dr. Tait has called Tucson home, with his wife Lisa and their two young boys. A pivotal injury in 2012 changed his personal path and his entire practice philosophy. From one of managing pain to a comprehensive approach to create freedom from pain, so that he could return to an active lifestyle. That experience focused his future training and ongoing mentorship in the growing fields of Regenerative Medicine, Integrative Orthopedics, and Functional Medicine. Beyond the practice, Dr. Tait has authored three books and has created two courses on his Integrative Regenerative approach to Orthopedic care and optimal health.
