Street outreach services (SOS)


Beth Rittenhouse-Dhesi, Director of Community Services

Beth joined SFCCC in 2004, after stints as a case manager, program manager, and mental health policy advocate, including 5 years in HIV and homeless services at an SFCCC member clinic. Favorite parts of her job include oversight of Street Outreach Services (SOS) and its Veterinary Street Outreach Services (Vet SOS) project.
