After taking a brief break from acting, Maher came back to TV in 2009 as a guest star in Lifetime Television's pilot episode of Drop Dead Diva, followed by 2010 guest appearances in the second season of The Mentalist (CBS), the first season of Human Target (FOX) and the second season of Warehouse 13 (on Syfy).

In 2011 Maher landed a role in the television series The Playboy Club. He played Sean, a closeted gay man who is in a sham marriage with a closeted lesbian Playboy Bunny.
