The Society of Diplomates

In 1946, Harrisburg area physicians established an organization with the following goals:

  • Improve the quality of medical services.
  • Promote the mutual interests of Board-certified physicians in the area.
  • Become better acquainted with fellow members.
These charter members established that "a formal dinner meeting will be held annually, at which time the membership will be addressed by a speaker of outstanding reputation". For over seventy-five years, medical professionals from the Harrisburg area have come together for an evening of fellowship and learning. Membership is open to any board-certified physician in Central Pennsylvania, and new members are always welcome.
