She graduated cum laude from Virginia Tech in 2004, majoring in Human Nutrition, Food, and Exercise after which she received her Doctorate in Physical Therapy from the University of Maryland, Baltimore.

Dr. Sladek enjoys all areas of physical therapy, but her primary interests are in orthopedic sports medicine, manual therapy, vestibular rehabilitation, and balance training/fall prevention. Sabrina authored a research paper on rehabilitation for Tommy John Surgery in a baseball pitcher and another on Yoga and Low Back Pain. While working at St. Joseph’s hospital in the orthopedic rehab clinic, Sabrina watched a total knee replacement surgery and says it gave her a whole new understanding for those who undergo a joint replacement.

As a former competing athlete, Sabrina brings not only a wealth of expertise based on her schooling, but also invaluable insight gained from her personal experience as an athlete. She competed in soccer and basketball, but readily admits that she enjoys playing all sports. Sabrina has run the Marine Corps Marathon, a number of half marathons, and played basketball in the wheelchair basketball tournament against the wheelchair basketball team of Baltimore Maryland (Ravens). She shares that being an athlete allows her to relate to the emotional component as well as the physical and rehabilitative components of therapy.

Her patients have described Sabrina and her treatment as providing “a true concern for my well-being”, “a program that was challenging and expedited my recovery”, “a customer first approach”, “providing knowledge and guidance”, and describe her as “professional, knowledgeable, caring, and personable”.

Danielle Gross, PT, DPT – Doctor of Physical Therapy

Danielle received her Bachelor’s degree in Healthcare Management and her Doctorate of Physical Therapy from Misericordia University in Dallas, Pennsylvania. While at Misericordia, she played Division III Lacrosse, remained on the dean’s list, was inducted to the Sigma Beta Delta International Honor Society for Business, Management, and Administration, and initiated/coached a local high school varsity Lacrosse team for two years.

While on clinical during completion of her doctorate, Danielle found what she is truly passionate about. Helping people resolve their symptoms of vertigo, dizziness, and imbalance is something that she finds extremely interesting, rewarding, and important. When Danielle was learning about the balance system, inner ear disorders, and more about the people suffering from them, she realized that this was a problem that hit very close to home. She recognized that her twin uncles had been suffering from an inner ear disease for years without knowing it. Seeing how greatly inner ear/balance disorders can affect a person’s life only added fuel to her passion.

Outside of the clinic, you can find Danielle remaining active through running and hiking. She also sometimes travels on weekends to help with triathlons as a handler to parathletes, or as a classifier to USA Paratriathlon.
