Richard Gresham was a male Human Starfleet ensign who served aboard Deep Space 9 in the 24th century.
In 2383, Ensign Gresham helped to evacuate civilians from Deep Space 9 to Bajor aboard the USS Rio Grande when Andorian explosives were found in the fusion core of the station. After detecting the later attack on Deep Space 9 by the Typhon Pact, Gresham transported Ro Laren, Cenn Desca, Jefferson Blackmer, John Candlewood and Zivan Slaine out of Ops before Deep Space 9 exploded.
