Chris Gayler

I grew up in Castro Valley and attended UC Santa Barbara College and lived there for 5 years. I met and married my wife Natalie at Santa Barbara. After we married we moved back to the San Francisco Bay Area to start working for the family business.

I have been working side by side with my Dad for the last 8 years as General Manager and at some time in the future, I expect to become the 3rd generation owner. My wife Natalie initially worked for Gayler Construction too but has since become a full time mom taking care of our two boys Ethan and Zach. When I’m not working I enjoy water skiing, snow skiing, reading and being horrible at golf.
