Peter Whitelock

Head of Staff

Peter hails from San Diego, originally, and attended San Diego State University for a couple of years before transferring to the University of Colorado, Boulder. While at college, he felt a calling to serve the church, and seminary training took him to Fuller Theological Seminary  and Princeton Theological Seminary for three advanced degrees, all told. He often states that being a student for life would have been an attractive career option if it were an option!

Anne and Peter have three wonderful adult children: Colleen, Evan and Aaron. In his spare time, Peter likes to read, travel and ski. His favorite place to be on vacation is still the beach, and he confesses to being an analog soul in a digital world as is reflected in his hobby of restoring vintage audio equipment and collecting vinyl albums.
