About Me

Joseph Thomas, DO, MBA is a proud Pennsylvania native who returned to his home city of Harrisburg in 2017 to join the esteemed residency program at PinnacleHealth, and later joined UPMC Primary Care Good Hope. Most recently, he embarked on a new journey as a solo practitioner.

Our Journey

Dr. Thomas is honored to carry forward the legacy of John E. Muscalus DO, Family Practice, which will now be known as Dr. J Thomas Family Practice. Dr. Muscalus, a cherished friend and mentor, has wholeheartedly embraced this transition after an impressive 39-year tenure as a solo practitioner.

A Legacy of Care

We extend a warm and heartfelt welcome to all who choose to become part of our extended family.

Our unwavering commitment to exceptional patient care will continue to drive us forward. Together, we will continue to uphold the principles that have guided us for generations.

Please join us on this journey as we build upon the strong foundation laid and strive to make a positive impact on the health and lives of our valued patients.
