Commander Clarissa Glenn was a 24th century Human woman who served Starfleet as the commanding officer of the Federation starship USS Galen. She was an intelligent, articulate, and eminently professional officer. She had completed both her medical training and a command track. She was young and quite attractive, a few inches taller than the Doctor and in excellent physical condition. Her hair was long and reddish blonde, usually kept neatly braided when on duty. Her eyes were an unusual shade of light green. Reginald Barclay developed a crush on her shortly after being assigned to the Galen. (VOY novel: Unworthy)
