Thank you for your interest in volunteering at COTS

Hundreds of volunteers give over 40,000 hours a year of their precious time to our work — the equivalent of about 21 full-time employees. We look forward to getting to know you, learning about your talents and interests, and matching you to just the right volunteer opportunity.

See below for the volunteer opportunities we have available at COTS.
