Character Bio

Mike Callahan photo
Diego Klattenhoff plays Mike Callahan on "Mercy." Klattenhoff was born outside of New Glasgow in Nova Scotia and moved to Toronto to pursue acting at the age of 19. He studied in theatre workshops for a number of years, while bussing tables, bartending, and adapting to life in Toronto.

Klattenhoff studied with some of Canada's most respected acting coaches, including David Rotenberg, Bruce Clayton and Rae Ellen Bodie, and eventually his dedication and persistence paid off. His first big break was in "Mean Girls," starring Lindsey Lohan and Rachel McAdams. Mark Waters directed this cult favorite.

Additional credits include guest starring roles on numerous films, movies of the week, and television series such as "Smallville," "Psych," and "Supernatural," as well as recurring roles on "Men in Trees" and "24." Klattenhoff also appeared as a series regular on Canada's CTV's "Whistler" and starred in JJ Abrams' pilot, "Hope Against Hope."

Before acting, Klattenhoff's dream was to become a professional baseball player. When time permits, he still loves to play on the diamond as well as indulge in golf, football, hockey and swimming.

Klattenhoff divides his time between Toronto, Vancouver, and his new home in Los Angeles
