Her practice philosophy is patient centered and based on individualized care. She believes successful outcomes typically result from a combination of manual therapy, exercise, neuromuscular reeducation, patient education, and collaborative problem solving. She has worked with a diverse population ranging from kids, student athletes, patients with work injuries, pregnant women, and with geriatric patients.  She cares about education and has experience teaching in a cardiac rehab program, a back education and injury prevention program, body mechanics and transfer training for nursing staff, and currently is faculty for the University of St. Augustine’s Doctor of Physical Therapy Program. ​
