It was my first New York audition. I'm not a dynamic auditioner. In fact, it was how I got my agent. They almost didn't hire me because they thought I didn't sing well enough. I can say that Gillian Lynne (Associate Director and Choreographer) told me that of all the people she worked with, Steve Barton and I were the best Munkustraps. I do feel that I did master that role. As difficult as that show was, it was a great experience.

  • "I also love the immediate gratification I get from a live audience. For me, the best thing about what I do is being able to make people feel good and maybe go away with some sort of message."
  • "Every actor wants to be in the hot new thing, and it's easy to get into that toxic mindset of `What's this doing for my career? Who cares about this show that's been open for 15 years?' I take a breath and remind myself that I have a great job. I've grown as an artist doing Cats, and that's all that matters."
  • "For me, success is defined by the wonderful moment you learn something about yourself or you realize you did something you didn't think you could do before."
  • "In retrospect, my life has been fairly easy and the transitions relatively easy as well. I am no big overnight success but instead I've worked my way up. I always try to reinvent myself with each role I get."
