210-735-4022 x325

Position: ​Director of Enrollment Management

Education: ​BA in Sociology from University of Southern California

What did you do before you came to Keystone: ​I’ve been in admissions for 14 years but all in California. Before I relocated to San Antonio in July I was the Director of Admissions at a progressive Mandarin immersion school in San Francisco.

Why do you like working here: ​The minute I set foot onto Keystone’s campus it just felt like home. The warmth that is exuded on a daily basis only makes my job that much easier when talking to prospective families.

Hobbies/pastimes: ​Dance, dance, dance. When I lived in CA, along with doing admissions, I was also a part-time dance instructor. I taught a dance cardio class at an all female (and female owned) studio in Oakland.

Something (personal or professional) you’re proud of: ​I’ve never lived anywhere except CA. The biggest move I ever made in my life was from Southern California to Northern California (ha ha). The fact that I’m living in a part of the country I never imagined is quite astonishing. The fact that I really like it and am thriving is even more astonishing!!!!

Favorite/inspirational book: I’m the type of person who doesn’t have a favorite because there are just too many good things and experiences out there. However, one book that has stuck with me and I think about quite often is “A Little Life” by Hanya Yanagihara. ​

Favorite quote: ​”Every woman is a rebel, and usually in wild revolt against herself.” – Oscar Wilde

Something (personal or professional) you’re proud of: Personally, I’m proudest of my wife, children and grand-children. They remind me every day that life is a gift. Professionally, I’m proud that I’ve balanced my work as a teacher and theatre artist. In 2007, My wife and I founded the Classic Theatre of San Antonio. We worked with 4 other local artists and 1 patron of the arts to create a classical repertory company that would produce high quality professional productions of great dramatic literature. The Classic is still going strong, and I’m proud to have been a part of starting something that continues to enhance the quality of life in San Antonio.

Favorite/inspirational book: The Alchemist by Paolo Coelho. It’s a simple fable about following your dreams. If you tell the universe your dreams; the universe will conspire to make them come true.
