After completing her Bachelor’s degree in Biology with an emphasis on Pre-Med studies, Dr. Ashenfelter obtained certification in Applied Behavioral Analysis from the Center for Autism and Related Disorders. She discovered that Physical Therapy was her true calling as it would allow her to combine her passions for physical activity and intellectual development in order to make a measurable difference in the quality of life of those she treated. 

In the graduate program at Franklin Pierce University, Dr. Ashenfelter worked in a diverse variety of patient clinical settings including home health care, outpatient rehab, outpatient sports PT, inpatient acute rehab, and even an animal rehab clinic, in order to maximize her exposure to many different disorders of the neurological and musculoskeletal systems and treatment methodologies.  She graduated with her Doctorate in Physical Therapy, and is licensed in the state of New Hampshire. Additionally, Dr. Ashenfelter is certified as a clinician for LSVT-BIG, the gold standard treatment for patients with Parkinson’s Disease. 

Recently, Dr. Ashenfelter was fortunate enough to give birth to a daughter of her own, and as a result, has opted to specialize in perinatal, neonatal, and early childhood services.
