Throughout his career as a clinician, he treated a diverse range of individuals—from weekend warriors to collegiate and professional athletes—while working in various settings, including physician offices, outpatient orthopedic practices, and local universities. These experiences exposed him to the unique challenges athletes and active individuals face when trying to transition from injury recovery back to peak performance.

Driven by a desire to serve his patients better, Dr. Joyner pursued advanced certifications, becoming a Board Certified Orthopedic Clinical Specialist (OCS), a Certified Strength and Conditioning Specialist (CSCS), and a Performance Enhancement Specialist (PES). He also became a USA Weightlifting Level 1 Coach (USAW-1) and trained in advanced techniques such as Trigger Point Dry Needling, Cupping Therapy, and Manual Therapy. These tools allowed him to refine his approach to treating athletes and active individuals, blending rehabilitation with performance training.

In 2019, Dr. Joyner founded Apex Performance Therapy with a clear mission: to create a space where rehabilitation and athletic performance meet. He envisioned a clinic that not only helps patients recover from injury but also equips them with the tools to return stronger, more resilient, and ready to excel in their sport or active lifestyle. At Apex, training and rehab are seamlessly integrated to reduce injury risks and restore optimal performance, fulfilling the mission of truly “bridging the gap” between rehab and sports performance.
