St. Elsewhere is an American medical drama television series created by Joshua Brand and John Falsey, that originally ran on NBC from October 26, 1982, to May 25, 1988. The series stars Ed Flanders, Norman Lloyd, and William Daniels as teaching doctors at an aging, rundown Boston hospital who give interns a promising future in making critical medical and life decisions. The series was produced by MTM Enterprises, which had success with a similar NBC series, the police drama Hill Street Blues, during that same time. The series were often compared to each other for their use of ensemble casts and overlapping serialized storylines.
