COTS benefits from over 50,000 hours of volunteer service each year - that is equivalent to 24 full-time staff positions!

Many thanks to our valued volunteers!


COTS
is strongly supported by the people of Sonoma County and works cooperatively with numerous social service providers in our region. We provide initial training and on-going volunteer support.
