Here she participated in internships with local outpatient Physical Therapy clinics, conducted research regarding the impacts of exercise on aging and brain health, and taught youth dance classes. She then continued her schooling at The George Washington University to pursue her Doctorate of Physical Therapy.
Katharine’s interest in movement science stemmed from a long history in dance and sport. She further became invested in Physical Therapy when volunteering at inpatient rehabilitation and skilled nursing facilities, where she saw the impact that a Physical Therapist can have on a wide variety of populations.
Katharine has completed a diverse range of clinical internships including outpatient settings with a variety of demographics and abilities, an inpatient rehabilitation hospital, and pediatric in/outpatient. She uses this experience with varying populations to best educate patients and to create plans of care that relate directly to each unique individuals needs and goals.
In her free time Katharine enjoys long walks and runs to find hidden gems around the city, reading, and feeding the people around her.
Elle McNeil, PT, DPT
Elle grew up in Richmond, Virginia, and earned her Bachelor of Science in Exercise Science with a minor in Dance from The George Washington University. She continued her education at George Washington, where she completed her Doctor of Physical Therapy degree.
Having trained in ballet at the pre-professional level, Elle was first introduced to physical therapy through her own experiences recovering from dance-related injuries. Her passion for the profession grew while working as a physical therapy technician at a clinic serving her local ballet company, as well as in a private outpatient orthopedic practice.
Throughout her clinical education, Elle gained experience across a variety of settings, including outpatient orthopedics, acute care, and a specialty performing arts rotation with Boston Ballet. Drawing from her experience across a variety of clinical settings, Elle works closely with each patient to develop individualized treatment plans that align with their goals, lifestyle, and movement needs. Her primary clinical interests are performing arts rehabilitation and sports/orthopedic medicine.
Outside of the clinic, Elle enjoys strength training, attending yoga classes, and exploring new neighborhoods/restaurants throughout the Washington, DC area.
