The volunteer-based leadership of Harmony consists of a board of directors led by an executive team. All are elected positions.

The executive team includes the president, two vice presidents, treasurer and secretary; each role is elected based upon a one-year term. The board is comprised of up to 15 members, each of which serves in a staggered two-year term format so that continuity is maintained on an ongoing basis. The most recent past president of Harmony may serve on the board in a non-voting, ex-officio capacity.
