Rebecca Wykle, PT, DPT, SCS
Rebecca is a Board-Certified Clinical Specialist in Sports Physical Therapy who graduated from the University of North Carolina at Chapel Hill (GO HEELS!) and East Carolina University, where she obtained a Bachelor’s degree in physical education (BS) and Master’s degree in Physical Therapy (MPT). She moved to Chattanooga with her husband in the Spring of 2001 and begin working in the field of outpatient orthopedics. Early in her career, she witnessed a corporate push for increased revenues, patient numbers, and therapist productivity, and therefore, she observed many shortcomings in typical patient care models in the area. She desired to give her patients more time with a one-on-one approach. She met and worked closely with Keri Todd who shared the same feelings and vision. Together, they created Peak Fitness and Physical Therapy in 2011. After Keri moved away from Chattanooga, Rebecca continued to push for a new set of standards in patient care in the Chattanooga community as a sole proprietor of the business.
As Peak grew, so did Rebecca’s continued desire to learn. She completed her certification for Pilates for Rehabilitation through Polestar in 2014 to become a certified Pilates Instructor. In 2020, she earned her doctorate in physical therapy (DPT), and later that same year, she became a board certified sports physical therapy clinical specialist (SCS).
Rebecca and her family (husband, Chad and children, Gabe and Nora) felt a pull back home to the mountains and foothills of North Carolina and made the difficult decision to move back there in 2021. She asked her long-time friend and colleague, Marie Howell, to join her as a partner in business. Despite the 4.5 hour drive, Rebecca continues to be an integral part of Peak Fitness and Physical Therapy and will frequently treat patients in the clinic!
