About Us

Professional Commitment
Mark Manfredi and Mitch Gottentag, Owners ADVANCE Orthopedic and Sports Therapy, P.C. was founded in 1988 by Mitchell Guttentag and Mark Manfredi, PT with the goal of providing the highest level of physical therapy care to the people of the Merrimack Valley. From the day we opened our first office, in a small 150 square foot room, inside a local health club, our objective was to provide service that exceeds every patients expectations. Providing excellent service, in combination with staying present with latest treatment techniques, and attending continuing education courses has allowed our practice to grow as we moved into our 600 Clark Road location and add additional skilled therapist to our rehabilitation team. All the therapist at ADVANCE, are posed to meet the ever changing challenges of health care reform while keeping their professional commitment to the patient, providing the best patient care and education and allowing each patient to achieve their rehabilitative goals.
