COTS staff collaborates between case management, medical care, and community resources to ensure clients have access to the care they need, whether they are staying in short-term shelter or are in one of our long-term housing programs. All of our services are designed to give clients a chance at finding and keeping housing.

Case Management

Every client in our shelter or housing programs is matched with a Case Manager or Housing Navigator who helps them identify and address their individual barriers to housing. That can include helping clients work towards long-term independence and stability, or matching clients with disabilities access permanent supportive housing and care. As part of this service, we also offer income development assistance, which helps people find jobs, increase their wages, and apply for a range of earned benefits so that when they find housing, they are able to keep it.

Mary’s Table

COTS provides an average of 7,000 healthy meals per month from our kitchen at the Mary Isaak Center to anyone experiencing hunger or poverty, and the need is growing. We serve three hot meals each day to our shelter residents and lunch is currently open to any person struggling to make ends meet. In July 2019, we opened Mary’s Table to the public for dinner, too – expanding our services and reaching even more of those facing hunger in our community.

At COTS, we believe that good nutrition is a human right. By serving our clients and neighbors the best possible meals, we allow them to focus on building resilience, nourishing their families, and achieving their goals for long-term stability and housing. Generous funding from a grant partner has increased and improved the quality of our food services by allowing us to procure and use more fresh vegetables and fruits, including organic options whenever possible.

If you need long-term support with food, we encourage you to contact the Redwood Empire Food BankSonoma County 211, or your healthcare provider.

Healthcare & Wellness

The Petaluma Health Center has an onsite clinic at the Mary Isaak Center, accessible to clients residing in the Emergency Shelter and to members of the public. Nursing interns provide enrollment in primary care and referral to primary care providers. Services include short-term therapy for stress, depression, crisis, or mental illness. Referrals are also available for longer-term care.

In the years to come, COTS hopes to expand our portfolio of available housing for clients while increasing the number of people served by our Diversion and Rapid Re-Housing programs. We continue to use evidence-based strategies rooted in the expertise of our dedicated staff, and the results of our programs speak for themselves. At our last audit, 85% of our Rapid Re-Housing clients remain stably housed a year after exiting our program. With the support of our community, we believe we can end homelessness in Sonoma County within our lifetimes.


COTS Outreach program focuses on connecting those living in encampments, streets, and vehicles with much-needed supports including shelter, meals, legal advocacy, medical care, and substance abuse treatment.

Our team of Outreach Specialists connects with individuals experiencing homelessness and offers them the COTS programs and supportive services most appropriate for their needs. Outreach Specialists may transport unsheltered individuals to medical or legal appointments, may serve as advocates at Homeless Court, and can refer individuals directly into County detox and/or rehab programs and provide additional support during and after treatment. Outreach Specialists work collaboratively with the Petaluma Police Department to ensure safe and trauma-informed engagements with unsheltered individuals.

COTS’ Outreach Specialists also serve as a resource for businesses in Petaluma. Outreach Specialists are available to present to hospital staff or other business leaders about the presence of unsheltered individuals in our City and what strategies can be used to address concerning behaviors.
