In Marin County, reported syphilis runs about 68% lower than the US average. If you've had a recent risk or simply test on a regular schedule around San Anselmo, California, you can weigh different options for STI testing: public clinics keep costs down, private labs prioritize speed, and at-home kits trade a clinic visit for convenience.
Available testing centers
9 testing options are listed for San Anselmo, CA. The nearest, Planned Parenthood Northern California, is about 1.8 miles away. Compare community and public clinics, private labs, and at-home kits below.
Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Planned Parenthood Northern California in San Rafael tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis B and C on a sliding-scale fee open to everyone; HPV and hepatitis B vaccines, PrEP, and PEP are also available. Appointments are required.
Spanish is available through on-site staff and a live interpretation service for other languages, not a phone handset passed across a desk. That means clinical nuance, dosing instructions, and follow-up plans are communicated directly in the exam room, in the language the conversation actually requires.
As a Title X-funded clinic, Planned Parenthood Northern California in San Rafael provides legally confidential family planning services to minors. Meaning parental notification is not a condition of care. That federal designation is what makes the confidentiality guarantee enforceable, not a policy preference.
Without PrEP or PEP available at the clinic managing your sexual health, you absorb the delay and cost of a separate provider. A gap that has real consequences for both ongoing prevention and time-sensitive treatment. Planned Parenthood Northern California prescribes and manages both here, keeping prevention continuous.

STD stats & rates
How reported STI rates in Marin County, the county that includes San Anselmo, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~16% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#38 of 58 California counties for chlamydia, a higher rate than 34% of the state
| Infection | Marin County | California | United States |
|---|---|---|---|
| Chlamydia | 294.4 749 cases ▼ 40% | 491.1 | 492.2 |
| Gonorrhea | 97.1 247 cases ▼ 49% | 190.2 | 179.5 |
| Syphilis (P&S) | 5.1 13 cases ▼ 69% | 16.3 | 15.8 |
| Syphilis (early) | 7.1 18 cases ▼ 63% | 19.1 | 16 |
| Syphilis (late/unknown) | 12.6 32 cases ▼ 73% | 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 Marin County, chlamydia has risen from 214.2 to 294.4 per 100,000 (37%), gonorrhea has risen from 50.7 to 97.1 per 100,000 (92%), and P&S syphilis has fallen from 6.9 to 5.1 per 100,000 (26%).

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 Marin County.
Local HIV snapshot
Marin County HIV care continuum (2023)
Marin County recorded 10.8 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Marin County residents living with HIV, 74.8% are in care · 71% 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 Marin County tests for syphilis.

Local resources & officials
Data & references
Local context
Sir Francis Drake Boulevard cuts through the heart of San Anselmo, and for the younger adults renting here amid median rents that stretch most budgets, the calculus of a weekday errand looks different than it does for the two-thirds of residents who own their homes. That ownership-heavy town, with its settled married households and families averaging nearly three people, still holds a meaningful share of people in their late teens and twenties navigating new relationships and the kind of health maintenance that tends to get crowded out by work and cost pressures alike.
Those younger residents face a particular version of that squeeze here. With nearly three in five households earning six figures, San Anselmo reads as prosperous, yet renters paying close to two thousand dollars a month carry a different set of priorities when discretionary spending comes up. Regular STI screening can feel like an afterthought when money is tight and scheduling is complicated, but the county STI picture makes the case for staying current even when life is busy.
Getting to the options listed on this page is mostly a car trip, typically out along Sir Francis Drake or Red Hill Avenue toward San Rafael or beyond. That drive is short enough that it rarely becomes a genuine obstacle, and for anyone near Lansdale Station Park or passing through Terra Linda on a weekday, folding a clinic visit into an existing trip out of town keeps the whole thing straightforward.
Getting there
San Anselmo scores 12.39/20 on the EPA walkability index, so many trips are walkable or a short ride, though a car still gives you the widest choice of testing centers.

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.
