I have been driving from Alton to do therapy with Mark for about 12 years. The drive is well worth it. Mark has helped me with many problems. Back, hands, wrists and a knee replacement. I trust him with my whole being!! I love exercising with him twice a week. I have osteoarthritis and rheumatoid and he is always looking out for me while exercising. I highly recommend him for his one and one caring techniques.
