Ben Warren was an anesthesiologist at Grey Sloan before he decided that he wanted to become a surgeon. He went through his residency again before deciding that he wanted to pursue another avenue of saving lives after some controversial choices she made as a doctor.

He eventually became a firefighter, which took him to Station 19. He also often serves as a paramedic because of his medical background.

He got a medal of honor for his heroic save of individuals in a rehab house fire.

He may reconsider his job again in order to honor the agreement he made with his late colleague Dean Miller's parents when he settled with them for custody of Dean's daughter, Prue.

Ben Warren is married to Miranda Bailey, the chief at Grey Sloan Memorial.
