Leadership Team
CCHS Staff
David Stegman, Executive Director
David is the Executive Director for the Contra Costa Humane Society joining CCHS in 2009. He has dedicated years of service to helping animals and their caregivers. Before joining CCHS, David was Executive Director of Valley Humane Society in Pleasanton and prior to that he was Executive Director of Tony LaRussa’s Animal Rescue Foundation (ARF) in Walnut Creek.
He is currently expanding the programs and services offered by CCHS to include the AniMeals Programs providing pet food for the companion animals of financially impacted families through the Contra Costa Food Bank and Kitty Corner, housing Contra Costa County Animal Services’ often overlooked adult cats until they can be adopted.
David has been an officer for various community organizations including Leadership San Ramon Valley, Danville Chamber of Commerce, San Ramon Valley Kiwanis Club and the San Ramon Valley Area Planning Commission. He was named Citizen of the Year by the Danville Community Services. David currently lives in Danville with his wife Jeri and their rescued dogs Mugs and Sparky.
Chrissy Wilberg, Adoption and Office Manager
Chrissy has been with CCHS since February of 2005 and manages the agency’s Adoption and Foster Programs, Kitty Corner and the Emergency Medical Fund. She says it is the best of both worlds – office time mixed with hands-on time with the animals. Her love for the job stems from her passion for finding permanent homes for needy animals.
Chrissy graduated from Sonoma State University in 2002 with a Bachelor of Arts degree in Biology with a concentration in Zoology. After graduating she was a front-office manager for a companion animal veterinary practice. On weekends she often worked as an animal keeper for a wildlife rescue center and volunteered working with a wide variety of wildlife at the Oakland Zoo.
Chrissy and her husband live in the west county and are owned by a playful Pitbull mix and an energetic young cat. Her interests include hiking, waterskiing, yoga, traveling and spending plenty of time with her friends, family, husband and animals.
