Christina Snyder
President, PTA

Tina, owner of PMC, completed her Associates of Applied Science in Physical Therapy at Carroll Community College and completed her Bachelor’s degree at University of Maryland. She performed clinical field work at Kennedy Kreiger Institute outpatient pediatrics and Kernan Orthopedics and Rehabilitation Hospital spinal cord injury unit, which ignited her passion to work with the pediatric population. Tina has been working in the physical therapy field for over 8 years in multiple clinical settings including outpatient pediatrics, outpatient adult orthopedics, and home health. She has experience treating adult and pediatric neurological conditions, athletic injuries, and medically complex diagnoses.


In recent years, Tina peaked an interest researching sensory integration and the role physical therapy can take in the treatment of sensory processing and related disorders. This research, along with a growing desire to treat her patients in a sensory rich, state of the art, and comforting environment, compelled Tina to open PMC’s doors in March of 2017. “I’m very proud of what PMC has become, and our team of staff here makes PMC a family.”


When not treating patients or greeting new friends at PMC, you’ll likely find Tina researching new equipment, techniques, and strategies to add at PMC to help children succeed with their rehabilitative goals. Tina is passionate about providing families with support, and helping children overcome obstacles to achieve new milestones. “I love breaking through to our kiddos in therapy sessions; when they achieve a new skill or communicate in a new way, I celebrate each accomplishment with them and it inspires that passion yet again!” Tina’s most important motivation is her three young boys (Michael, Mason & Maddox) who you may see swinging around at PMC, and her husband, Brian. She loves spending time with her family hiking, swimming, and going on family vacations.
