About Us

Dr. Jennifer Payne McCartney, PT, DPT
Director/Chief Physical Therapist

Jen was raised in the Finger Lakes Region of Upstate New York. She decided at a young age that she wanted to be a physical therapist. When it came time to look for a college, she did not have to look far to find the rigorous program at Ithaca College where she attained her BS in Clinical Science and MS in Physical Therapy in 2004/2005 respectively. She completed her Doctorate in Physical Therapy from Mass General Hospital Institute of Health Professionals in January of 2015. She is certified in a unique method for rapid healing, rehabilitation and injury-free training and conditioning called the Burdenko Method (www.Burdenko.com). Along with her extensive training in the science and application of physical therapy techniques, she truly cares for her patients and she works for positive resolution of their pain and dysfunction. Jen promotes wellness to all of her patients encouraging them to live an active lifestyle especially upon completion of physical therapy.  When not found at Horizon, Jen enjoys spending time with her family and friends, sailing, snorkeling, SCUBA diving,  hiking, and traveling.
