Meet Dr J.

Dedicated to Compassionate, Patient Centered, Care

Joseph Thomas, DO, MBA is a dedicated primary care physician proudly serving the communities of Hummelstown, Hershey, and Harrisburg in central Pennsylvania. Born and raised in the Harrisburg area, Dr. Thomas has a deep understanding of the region’s
healthcare needs and the challenges facing its residents.
With a strong commitment to compassionate, patient centered, and evidence-based care, Dr. Thomas is known for delivering high-quality, personalized treatment. His focus on primary prevention and chronic disease management led him to transition from large- scale primary care to independent practice—allowing him to prioritize meaningful long-term relationships with his patients. As both a patient advocate and a healthcare leader, Dr. Thomas works every day to make a difference in the lives of those he serves.

Philosophy of Care

Patients often share that their visits with Dr. Thomas are never rushed and consistently include thorough explanations, clear health guidance, and a well structured plan of care. Rather than making top-down decisions, Dr. Thomas emphasizes patient education empowering individuals to actively participate in their healthcare choices. A firm believer in “practicing what you preach,” Dr. Thomas applies this principle to his life, his family, and his practice. He recognizes that no two individuals are the same, and therefore, care should never be one-size-fits-all. “Understanding what makes each person unique is the key to discovering what will work best for them.”
— Dr. J

“Patients should not be lost in the healthcare system without physician guidance—especially in the face of growing demands, increasing populations, and pressures from large healthcare systems and insurance companies.”
— Dr. J

Residing in West Hanover with his wife and two children, Dr. Thomas is deeply committed to serving his local community. His diverse educational background and unwavering dedication reflect his commitment to providing comprehensive care and his continuous pursuit of knowledge in the healthcare field.

Shanda is particularly passionate about preventive healthcare through education and routine screenings, and her clinical interests include pediatric care, women’s health, minor wound care, and acute/urgent care.
