Posted January 11, 2017 · Report post My doctor highly recommended that I go to Peak Performance to help me in my recovery from PTTD (Posterior Tibial Tendon Dysfunction). There was significant discomfort and weakness in my ankle and the arch of my foot, making it a painful challenge to walk or stand for any period of time. Andrew and Peak Performance came through for me with flying colors. Andrew provided many helpful exercises and techniques that strengthen my ankle and significantly improve my mobility. My doctor was also pleasantly surprised over the progress made in such a short time. THANK YOU! Bonnie S. December 22, 2016 Share this post Link to post Share on other sites
