Born in Cardiff, Peter trained as a doctor at Brasenose College, Oxford and St. Bartholomew's Hospital Medical College, but chose an acting career just prior to graduation. Peter caught the acting bug as a teenager at the National Youth Theatre in Wales and his drama training was at the Guildhall School of Music and Drama in London. On leaving drama school in 1990, Peter made his television debut in Beeban Kidron's Screen Two production of "Antonia and Jane" before going on to play lead roles in three television drama series: "Alex" in Granada TV's Medics; "Lt. Nick Pasco" in "Soldier Soldier" for Central TV; and "Tom Walton" in "The Men's Room" (1991), a five-part series directed by Antonia Bird for BBC TV. For the next few years, Peter worked steadily in the UK doing several noteworthy productions, such as Pirandello's "Six Characters in Search of an Author", "Alun Lewis" in "Alun Lewis: Death and Beauty" for the BBC Wales and "Martin Chuzzlewit" for the BBC, as well as the movie "Uncovered", directed by Jim McBride. In 1995, Peter did a guest shot on "Highlander the Series" playing Methos, a 5000 year old Immortal, which led to a recurring role on the series and changed the theater of his work from the UK to America. He moved to Canada during the filming of "Highlander", then returned to the UK to play Tom Kirby in the Granada Television series "Noah's Ark." Back in Canada, he did two seasons of "Cold Squad" as Inspector Simon Ross and had roles in "X-Men 2- X-Men United" and "Catwoman". He received a Gemini Award nomination and a Christian TV Excellence nomination for best actor for his work in "The Miracle of the Cards". In 2006, Peter appeared on the BBC series, "Dalziel and Pascoe." Peter and his family relocated to Los Angeles in the fall of 2005 where he did guest shots on the series "Charmed," and "Medium" as well as "The Collector" for CTV in Canada. He revisited the character of Methos for the new Highlander movie, "The Source" and also played the title role in "The Last Sin Eater" directed by Michael Landon Jr. for Fox Faith Pictures. In the summer of 2006, Peter returned to the UK to join the cast of the popular medical drama "Holby City" for at least one year as Medical Consultant Daniel Clifford. Peter holds an Advanced Level Stage fighting certificate, is a former National Trampoline Champion and his personal best time for running the London Marathon is 3 hours exactly. Peter is married and he and his wife have a son. As of August, 2011, Peter has returned to medical school, attending the University of Vermont, to become a doctor. He graduated in May 2015.
