He was perhaps best known for his role as Lieutenant Tom Donnelly in the long-running television drama Love Is a Many Splendored Thing from 1969 through the show's end in 1973. Fellow Star Trek alumni Bibi Besch, Leon Russom, and Michael Zaslow were also regulars on this series. Stratton went on to co-star with Sharon Acker and Monte Markham on the short-lived series, The New Perry Mason. This was followed by guest appearances on Petrocelli (where he worked with Logan Ramsey and series regulars Susan Howard and David Huddleston), Mannix, Wonder Woman (with Kenneth Tigar), and The Fantastic Journey (with Jason Evers). Stratton also co-starred with John Glover and Kelsey Grammer in the 1983 mini-series Kennedy.
