Director of Rehabilitation, CSI Longevity & Human Performance
Shaun Johnson joined the CSI team in June 2026 as Director of Rehabilitation, bringing a diverse background in athletic training, performance care, and evidence-based rehabilitation. She is dedicated to helping patients return to activity safely and efficiently through individualized, high-quality care.
Prior to joining CSI, Shaun served as an Associate Athletic Trainer at California State University, Northridge, where she worked closely with the Matadors’ men’s volleyball and men’s and women’s track & field programs. Her clinical experience also includes working with elite athletes at the University of California, Santa Barbara (men’s soccer and softball), as well as national-level competitors through USA Volleyball and USA Beach.
Shaun earned her Master of Science in Athletic Training from California State University, Long Beach in 2023. During her graduate studies, she conducted research on the impact of mental health support on injury recovery timelines, earning recognition as the Outstanding Graduate Student in the Department of Kinesiology.
Before transitioning into healthcare, Shaun competed as a professional volleyball player internationally, spending two years playing in Hungary and the Faroe Islands. This firsthand experience as an athlete informs her empathetic, performance-driven approach to rehabilitation.
