Greg Zillmer
Camp Director

Greg returns for his eleventh summer as Camp Galileo Sunnyvale’s Camp Director. Twelve years ago, his love of working with children became a career during his first summer with Galileo as a Lead Outdoors Instructor. After earning his master's degree from the University of San Francisco, he went on to teach second grade in Los Altos and Cupertino. Three years ago, he made the move to Cupertino Middle School and now teaches many of his former campers as a sixth grade science teacher. Greg also has Galileo to thank for his recent wedding to a former Camp Galileo Camp Director.
