Chief petty officer Brossmer was a transporter chief aboard the USS Enterprise-D in 2368. Brossmer was on duty in transporter room 3 when the Enterprise-D came to the aid of a damaged Romulan science vessel late in 2368. When Brossmer transported Lieutenant Commander Geordi La Forge and Ensign Ro Laren back to the ship with a graviton field generator, their patterns became unstable. Despite Brossmer's best efforts to abort the transport, the two officers were believed killed when their patterns disappeared. Brossmer was played by Shelby Leverington.
