Mark is currently working on projects with both Hat Trick and The Forge. He has also recently written on the second series of Call The Midwife and E4 drama Youngers.
Mark has consulted on the BBC's BAFTA award winning series Casualty and led the core story team as well as writing multiple episodes of the show. His personal credits include the two-parter that kicked off the relaunch of the show as well as Episode 25, Sex And Death, of which the The Times said that "the plotting was comparable to ER at its best." He was also on the core writing team for long-running BBC series Eastenders.
Following this, Eggbox, created by Mark and Tom Bidwell was commissioned for a pilot for BBC Three with Jamie Thraves as director and produced by Hat Trick.
Mark also writes for the stage. His plays Crap Dad, Scuffer and Sunbeam Terrace, and Sherlock Holmes- The Best Kept Secret were produced at West Yorkshire Playhouse. In 2012 West Yorkshire Playhouse produced Mark's critically acclaimed adaptation of Louise Rennison's Angus, Thongs and Even More Snogging. Mark has also worked with young playwrights' groups as a tutor and mentor.
