The Board of Trustees for Developmental Disabilities Ministries has the ultimate authority over the organization – setting policy and directions, overseeing the finances, and hiring the President/CEO.

​

The board can have up to 15 members, all of whom are committed to DDM as a Christian ministry. It is self-perpetuating and uses a rotation system of five-year terms, with new members rotating on each year. The full Board meets four times a year with other committee meetings added as necessary.
