I tore my ACL in March 2017 and had a hamstring graft at HSS a month later. Worked with Dave for the last 6 months to rehab my knee. As a very active person, Dave was great in ensuring an aggressive program for me but also making sure I didn't push myself beyond my limits. Could not be happier - excellent service, great people, flexible with scheduling and super responsive (all around including reception and accounting). Unlike some of the larger physical therapists in New York, they have such incredible attention to detail and really develop a great personal relationship with you.
