Dexter Cast: Where Are They Now?
11. Geoff Pierson
The Role: Recurred as Tom Matthews throughout the series until joining the main cast for its final season.
Pierson, long a recognizable face in the world of television, didn't slow down one bit after Dexter's conclusion. In 2014, he turned up for spots on ABC's Suburgatory, Fox's Enlisted, TV Land's Kirstie and NBC's About a Boy, all of which have since been cancelled. He also reprised his recurring role on Castle, co-starred in the Hilary Swank-led You're Not You and appeared in the Scorsese-produced crime drama Revenge of the Green Dragons.
This year's been a little quieter, with guest spots on TV Land's The Exes and ABC's The Astronaut Wives Club. However, he was also a part of HBO's Jack Black series The Brink, which was renewed this past July for a second season next year and sees PIerson playing the United States Secretary of Defense as part of the show's main cast.
