Clark Atlanta University President Ronald A. Johnson submitted his resignation Friday after a meeting with his board of trustees.

Johnson was named president of Clark Atlanta on March 31, 2015. The historically black college celebrated its 30th anniversary as a stand-alone institution on July 1, the same day that Johnson marked his third year as CAU’s president. In 1988, Clark Atlanta was formed as a result of a merger between Atlanta University, founded in 1988, and Clark College, founded in 1869.
