Shaun credits his family with helping him stay grounded. "In my family it's like you come from a family of plumbers and go into plumbing. Not such a big deal," he says. "Fortunately, all the plumbers in my family had kind of paved the way. So if I had any questions about how to manage something or if I was afraid of something or didn't quite know where to turn, they were there."

Still, Shaun says his family never pressured him to go into show business. "Actually, I think that they hoped that we wouldn't be in it," he says. "I know my younger brothers, Patrick and Ryan, obviously felt a great deal of pressure after David had done it and then I had done it. But, ultimately, you have to find your own path."
