In 2000, it was back to Los Angeles to play Patrick’s brother, Dr. Ian Thornhart on Port Charles until the show’s run ended in 2003. He received two Emmy nominations for his role as the dedicated physician.

Back on the East Coast, Thorsten joined the cast of All My Children as Zach Slater from 2004 – 2011. He had a brief break to do Occupant and an a stint on Smash, before returning to AMC as Zach.

He added credits such as The Stafford Project, Animal, Falling Water, But Deliver Us From Evil and For Thine Is The Kingdom, while working on B&B and flying to the east coast to spend time with his family.
