Dr. Mark S. Williams is a board-certified Orthopaedic surgeon and the founder of
Susquehanna Valley Medical Specialties—one of Pennsylvania’s last independently
owned and operated healthcare facilities. A lifelong resident of Bloomsburg, Dr. Williams
graduated from Central Columbia High School before earning his B.S. in Biology from
Bloomsburg University. He went on to complete his medical degree at the Philadelphia
College of Osteopathic Medicine. He completed his internship and Orthopaedic Surgery
Residency at the Community General Osteopathic Hospital in Harrisburg, PA.
In 1997, upon completion of his residency, Dr. Williams launched Susquehanna Valley
Medical Specialties with a mission to provide high-quality, affordable healthcare to the
Susquehanna Valley. His commitment to innovation led him to become one of the first
surgeons in Pennsylvania to perform microinvasive, ultrasound-guided carpal tunnel
surgery, expanding access to advanced, minimally invasive care for local patients. He
also was one of the first in the region to perform out-patient total knee and total hip
replacements in his free-standing, ambulatory surgery center.
Dr. Williams is known for his team-oriented, patient-centered approach, prioritizing clear
communication, personalized treatment plans, and continuity of care for every patient
he serves.
He lives in Bloomsburg with his wife, Nicole, and his six children—Evan, Blaise, Chase,
Cael, Cooper, and Calista.
