Karen Rein is originally from Canada and attended the University of Virginia on a tennis scholarship where she received her Bachelor of Science. Her interest in physical therapy grew from her experience as a patient after seeking treatment for injuries sustained while playing high school and college sports.

Karen earned her Master of Science in Physical Therapy from the Medical College of Virginia and has over 25 years of experience as an orthopedic and sports physical therapist. She treats all types of musculoskeletal injuries and has a strong interest in shoulder rehab after spending 13 years at a shoulder specialty clinic in Scottsdale.

Following a foot injury several years ago, Karen began doing Pilates workouts and found that many of the principles aligned with her work as a therapist. She began incorporating more Pilates-based exercises into her treatments and was thrilled to find Tri Physical Therapy in 2019. Since then, she has been trained and certified as a Balanced Body® Pilates instructor. She has seen the reformers invaluable in helping patients improve balance, core strength, posture, and joint alignment.

Outside the office, Karen enjoys mountain biking, hiking, yoga, Pilates, pickleball, golf, skiing, and being a cool mom of two teenage boys.
