I have been going to William street sports&spine for almost a year due to chronic lower back pain issues. This is a great office that offer chiropractic, physical therapy, massage therapy, Accupuncture. It also has different massage beds that are quite ‘soothing’ the pain. The doctors, therapists all are knowledgeable and very friendly. Highly recommend!
