Amy Finnegan

Amy Finnegan, PTA - Physical Therapist Assistant

Amy Finnegan is a 1994 Pennsylvania State University graduate with a Bachelor's degree in Rehabilitation Services Education. Wanting to continue with a more holistic career path, Amy returned to Central Penn College and attained an Associates degree as a Physical Therapy Assistant.

For 20 years, Amy has focused her professional and rehabilitation intervention primarily in the outpatient world of Physical Therapy. Having many great teachers and colleagues over the years, Amy has developed skills and interest in the realms of aquatic therapy, lymphedema, orthopedics, personal fitness and becoming an instructor to teach classes of Silver and Fit as well as Tai Chi.

Amy feels that the first and foremost ingredient for the best patient outcome is the need for a teach approach…collaborative efforts made between the patient, PT staff and the medical interdisciplinary team of professionals.

Part two of patient success is as follows: listening to the patient followed by establishing a rapport of trust and respect between all involved. Educating and empowering the patient is also critical to improve one’s status and self-confidence. Lastly, providing the patient with the correct formula of individualized, functional and an appropriate level of fitness activities to improve patient’s overall prognosis. Amy is grateful to witness that success here at Drevna PT Associates by not only herself, but also through all of her colleagues’ efforts.

Amy resides in Lancaster with her husband and 2 furry children.

“Be the reason someone smiles today, it will be healthy for all involved.” – Amy
