Experienced, kind, professional, and most important -- effective. MPT has helped me and my son recover from injuries that required surgery. When Mark told me that I was ready to "graduate" from my four plus months of physical therapy, I was a little bit sad. It was an amazing experience. My recovery was tough, but Mark knew how to help me not only physically but also psychologically. He motivated me to push through the pain, and he was right every step of the way. He has done the same with my son, who is soon ready to return to playing soccer after six plus months of physical therapy. We are so delighted with his recovery. Plus the office staff is great - always friendly and responsive, ready to help....especially Jaimie. Thank you!
