I sit in my chair for work approximately eight hours per day. I began to have sharp upper and lower back pain and John Kwon administered several therapeutic stretching techniques that alleviated the pain immediately and also provided valuable information to help me keep the back pain away. In addition, he challenged me to live a healthier lifestyle by sleeping earlier and waking up earlier and that has made an immense positive impact upon my health and my relationship with my wife and kids. I've known John for more than 15 years and he is one of the most honest, real, passionate people I know. He's the first person I would recommend to anyone I know in need of physical therapy.
