A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

West County Health Centers in Sebastopol tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis B and C on a sliding-scale fee structure open to everyone, with same-visit treatment for bacterial infections; care is delivered in Spanish, and appointments are required.
West County tests for herpes simplex and both hepatitis B and C alongside the core bacterial infections, meaning a single visit can surface conditions that a narrower panel would leave undetected and unaddressed.
Many STI clinics hand off prevention medication management entirely. West County Health Centers prescribes both PrEP and PEP on-site, keeping the clinical relationship continuous rather than fragmenting prevention from diagnosis.
Spanish is a full working language at West County Health Centers in Sebastopol, not a triage accommodation, which means counseling, medication education, and PrEP management all proceed in Spanish without narrowing the scope of what gets addressed.

STD stats & rates
How reported STI rates in Sonoma County, the county that includes Sebastopol, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~22% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#25 of 58 California counties for chlamydia, a higher rate than 57% of the state
| Infection | Sonoma County | California | United States |
|---|---|---|---|
| Chlamydia | 362.6 1,747 cases ▼ 26% | 491.1 | 492.2 |
| Gonorrhea | 103.4 498 cases ▼ 46% | 190.2 | 179.5 |
| Syphilis (P&S) | 14.9 72 cases ▼ 9% | 16.3 | 15.8 |
| Syphilis (early) | 15.8 76 cases ▼ 17% | 19.1 | 16 |
| Syphilis (late/unknown) | 13.5 65 cases ▼ 71% | 46.7 | 29.5 |

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.
Between 2020 and 2023 in Sonoma County, chlamydia has risen from 269.2 to 362.6 per 100,000 (35%), gonorrhea has fallen from 131.5 to 103.4 per 100,000 (21%), and P&S syphilis has risen from 13.1 to 14.9 per 100,000 (14%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in Sonoma County.
Local HIV snapshot
Sonoma County HIV care continuum (2023)
Sonoma County recorded 9.1 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Sonoma County residents living with HIV, 86.8% are in care · 83.4% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Sonoma County tests for syphilis.

Data & references
Local context
CA 116 threads through Sebastopol as both South Main Street and McKinley Avenue, and the clinic options listed on this page sit anywhere from a short hop to a twenty-minute drive along those corridors, depending on where you live near Ragle Ranch Park or out toward English Hill. That distance is worth thinking about alongside the town's cost reality: with roughly half of residents renting at around fourteen hundred dollars a month and home values well above half a million, discretionary time and money carry real weight here, and a clinic visit that requires rearranging a workday can quietly become one that never happens.
The labor picture sharpens that point. More than two in three residents participate in the workforce, and unemployment runs at a level that leaves a meaningful share of households watching every expense, even among the four in ten earning six figures. Young adults in their late teens and twenties, who face the highest rates of chlamydia and gonorrhea infection, are often balancing shift work or hourly schedules that make mid-week appointments genuinely difficult to keep.
Sebastopol households average nearly three people, and just under half of adults are married, meaning sexual health decisions ripple outward from individuals to partners and families. The options listed here reflect that full range of circumstances, from the renter stretching a tight budget to the coupled homeowner navigating a shared schedule on Bodega Avenue.
Getting there
At 8.27/20 on the EPA walkability index, day-to-day errands in Sebastopol generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

Two things that actually depend on California law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
California permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
