UCSF Health-GoHealth Urgent Care in Mill Valley tests for gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis, and TB, treating bacterial STIs the same visit, on a fee-based sliding scale with insurance and Medicaid accepted; no appointment needed.
For anyone whose primary language isn't English (whether navigating a new diagnosis, asking about treatment options, or weighing prevention) interpretation services are available at UCSF Health-GoHealth Urgent Care without rerouting the visit. That standing capability means the clinical conversation happens in real time, with the provider, not as an afterthought.
PrEP at UCSF Health-GoHealth Urgent Care involves the full clinical loop: initial HIV testing to confirm eligibility, a prescription for daily oral medication, and the follow-up labs, typically HIV and kidney function, required to continue it safely. PEP is likewise prescribed on-site, meaning the course of antiretroviral medication starts without handoffs to another provider.
For anyone without a regular primary care provider, or paying out of pocket and trying to do a genuinely complete workup, UCSF Health-GoHealth Urgent Care's panel extends to herpes simplex, hepatitis A, hepatitis B, and hepatitis C alongside the core bacterial and HIV tests. That matters when a single visit needs to cover ground a basic panel won't.

Marin Community Clinics in San Rafael tests for gonorrhea, chlamydia, syphilis, herpes, HIV, hepatitis A, B, and C, and TB, treating bacterial STIs at the same visit, on a sliding-scale fee open to everyone, with appointments required. Spanish and Vietnamese spoken on staff.
Many clinics route non-English speakers through interpretation services that sit outside the exam room, a setup that works, but loses something when the conversation turns clinical. At Marin Community Clinics, Spanish and Vietnamese are spoken directly by staff, so the exchange between patient and provider stays intact.
Marin Community Clinics prescribes both PrEP and PEP on-site, which means ongoing HIV prevention is managed within the same care relationship: no separate specialist, no gap between testing and the medication that acts on what testing finds.
Skipping herpes or hepatitis from a panel means a gap that only shows up later, when symptoms surface or a partner discloses, and by then the path to diagnosis runs through a second clinic visit. Marin Community Clinics tests for herpes and hepatitis A, B, and C alongside the standard bacterial infections, closing that gap at the first appointment.

LifeLong Medical Care in Richmond runs by appointment, so scheduling ahead is the trade-off: what that appointment covers is gonorrhea, chlamydia, syphilis, herpes, hepatitis B and C, TB, and rapid or conventional HIV testing, with same-visit treatment for bacterial infections, on a sliding-scale fee, all services free.
Skip one lab fee and the follow-up often gets skipped too, cost is the most reliable gap in a treatment chain. At LifeLong Medical Care, testing, treatment, PrEP, PEP, and HIV/AIDS medical management carry no fee, so nothing in the care sequence gets quietly dropped because of what it costs.
Walk into most clinics speaking Mandarin or Korean and you're handed a workaround, a hotline, a scheduling delay, a staff member who speaks neither. LifeLong Medical Care in Richmond maintains on-site capacity in Chinese, Korean, and Spanish, plus interpretation coverage for additional languages, so clinical conversations happen in the room.
Ryan White Program funding at LifeLong Medical Care underwrites the complete continuum, from a rapid HIV test to ongoing HIV/AIDS medical treatment and medication adherence counseling, which means a positive result doesn't end at diagnosis; the same program that detected it continues managing it.

North East Medical Services in San Francisco runs on sliding-scale fees with Medicaid, Medicare, and private insurance accepted, covering gonorrhea, chlamydia, syphilis, HIV, TB, and hepatitis A, B, and C testing. With same-visit treatment for bacterial STIs and appointments required. Staff deliver care in Chinese, Korean, and Vietnamese.
North East Medical Services employs clinicians and support staff who work in Chinese, Korean, and Vietnamese: meaning prescriptions are explained, dosing is confirmed, and follow-up instructions are given in those languages by the people actually managing your care, not routed through an outside service.
A hepatitis C antibody-positive result at North East Medical Services leads directly into treatment managed within the same practice: antiviral therapy prescribed and monitored on-site in San Francisco, so the gap between confirmed diagnosis and an active treatment plan stays narrow.
Beyond gonorrhea, chlamydia, syphilis, and HIV, North East Medical Services screens for hepatitis A, B, and C in the same appointment: each test ordered, drawn, and tracked through the clinic's own records, with hepatitis A and B vaccines and hepatitis B and C treatment available without leaving the practice.

STD stats & rates
How reported STI rates in Marin County, the county that includes Tiburon, 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.

Data & references
Local context
Seen from the Lone Sailor Monument on a clear afternoon, Tiburon looks as settled and unhurried as any town on the Bay. That impression shapes how residents think about health care, too, including the kind of routine screening that benefits from being easy rather than heroic.
Most households here own their homes, and nearly two-thirds of adults are married, which can create a quiet assumption that sexual health testing is a concern for some other, more transient community. But the young adults in their late teens and twenties who do live here face the same exposure windows that define that life stage everywhere, and low-barrier access to testing is as relevant to a stable, long-established household as to any other. The options listed on this page serve Tiburon and the surrounding Marin corridor, including residents along Shoreline Highway and those closer to the Almonte and Sausalito sides of the county.
The practical complication is that Tiburon's workforce profile runs toward full engagement with low unemployment, meaning a large share of residents are carrying genuine professional schedules. With nearly two in three households in the higher-income tier, out-of-pocket fees at several of the listed clinics are workable, and a number of those options offer extended or weekend hours, so a lab visit doesn't have to wait for a weekday gap that may never open.
Getting there
Tiburon scores 11.51/20 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.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
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.
