William G. Koshinskie, PT, DPT

Facility Director / Physical Therapist

“I strive to ensure that first and foremost, all patients under my care receive an exceptional customer service experience.  I believe in active listening along with delivering a personalized/individualized treatment approach. I want patients to see the value that I can provide them in their rehabilitation process and what separates me, as a therapist, from the competition.

Furthermore, I seek to provide my patients with high-quality care while creating a laid-back and comforting atmosphere. I believe in assisting patients to obtain their optimal therapy results effectively and efficiently, and I enjoy doing so in a relaxed environment.”


William joined the PHOENIX team in 2018 and presently serves as the facility director and lead physical therapist for PHOENIX’s outpatient facility in Georgetown, DE. William has 19 years of clinical experience chiefly in the field of outpatient orthopedic care. His clinical expertise includes generalized orthopedic care, post-surgical care, McKenzie spine treatment, vestibular rehabilitation, concussion management, sports rehabilitation, work-related injuries, TMJ care, and geriatric fall prevention programs. William will be an integral part of the growth and development of the facility in the immediate and surrounding communities.

William resides in Rehoboth Beach, DE with his Bichon dog.  He is an avid college and professional football fan and enjoys a broad spectrum of activities that include cycling, boating, weight training, home improvement, golfing, spending time at the beach and traveling both domestic and abroad.
