Statement: Though I never attended college, I’ve had the great privilege of studying with such instructors as Doug Moston, Calvin Remsberg, Caitlin Adams, Wynn Handman and Joanna Gleason, among others, and at the Theatricum Botanicum in Los Angeles. However, my greater qualifications are my experience on stage, on camera and in the classroom and my genuine passion for teaching.
