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 Ramon tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis B and C on a sliding-scale fee, with appointments required; bacterial STIs are treated the same visit, and Spanish-language care plus interpretation services are available throughout.
Planned Parenthood Northern California in San Ramon provides Spanish-language services and interpretation for other languages as a standing part of care: meaning anyone navigating testing, treatment decisions, or PrEP conversations has direct, fluent support from the first question to the final prescription.
Without Title X status, a minor seeking confidential STI testing or family planning often faces a gap: a provider who must loop in a guardian, or a gap in coverage that stalls treatment. Planned Parenthood Northern California in San Ramon is a Title X clinic, so legally confidential services for minors are part of what this location actually delivers, not a workaround it can't offer.
Planned Parenthood Northern California in San Ramon prescribes both PrEP for ongoing HIV prevention and PEP when prevention needs to be immediate, which means a single provider relationship covers the full range of HIV prevention options, and coverage for uninsured PrEP patients is part of the program.

Axis Community Health in Pleasanton tests for gonorrhea, chlamydia, syphilis, HIV, herpes, and hepatitis A, B, and C on a sliding-scale fee open to anyone; appointments are required, and bacterial infections can be treated the same visit, with staff fluent in Hindi, Spanish, and Tagalog.
Axis Community Health conducts appointments in Hindi, Spanish, and Tagalog, which means test results, treatment instructions, and prevention conversations happen directly between patient and clinician. No relay, no lag in comprehension when the details matter most.
As a Title X-funded clinic, Axis Community Health provides family planning and STI services to minors with legal confidentiality protections built into the program: meaning a young person's visit, results, and treatment are not shared without their consent.
Axis Community Health's panel extends to herpes and hepatitis A, B, and C in addition to gonorrhea, chlamydia, syphilis, and HIV. Eight infections testable in a single appointment, so gaps in a standard four-test workup don't require a separate visit elsewhere.

La Clinica in Concord tests for HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B, and hepatitis C: the full panel runs on a sliding scale, with every service ultimately provided at no fee; bacterial infections are treated same-visit, and appointments are required.
Beyond gonorrhea, chlamydia, syphilis, and HIV, La Clinica's panel includes herpes simplex, hepatitis B, and hepatitis C. All ordered and resulted within the same clinical encounter. That reach means hepatitis C infection, which can progress silently for years, gets caught and managed here rather than surfaced only if a provider elsewhere thinks to look.
Spanish-language care at La Clinica runs through clinicians and staff who work in the language directly: histories are taken, results explained, and treatment plans laid out in Spanish without relay through a secondary service. That operational staffing keeps clinical nuance intact at every step of the encounter.
La Clinica accepts Medicaid, Medicare, and private insurance, and runs a sliding-scale fee for everyone else: the structure is built so that the final amount owed, regardless of payer or income, comes to nothing. No service on the panel carries a residual charge once that calculation runs.

LifeLong Medical Care in Oakland requires an appointment and covers HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis B and C, and TB testing on a sliding-scale fee: with free HIV and STI testing available, same-visit treatment for bacterial infections, and HPV and hepatitis A vaccines on site.
LifeLong Medical Care charges nothing for any service it provides: testing, treatment, vaccines, PrEP, and PEP all fall under that same zero-dollar line. That breadth means a single visit can move from an HIV test through a gonorrhea treatment to a PrEP initiation without a cost appearing at any step.
Spanish-language care at LifeLong Medical Care is delivered by staff, meaning clinical conversations (medication adherence counseling, STI prevention education, HIV test counseling) happen directly in Spanish without a relay. That staffing extends across both medical and counseling functions, not just intake.
Plenty of testing sites end their prevention work at the result. LifeLong Medical Care prescribes and manages both PrEP, the daily HIV prevention medication, and PEP, keeping the full prevention continuum within the same clinical relationship rather than splitting it across providers.

STD stats & rates
How reported STI rates in Contra Costa County, the county that includes Danville, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~18% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#19 of 58 California counties for chlamydia, a higher rate than 67% of the state
| Infection | Contra Costa County | California | United States |
|---|---|---|---|
| Chlamydia | 427.7 4,940 cases ▼ 13% | 491.1 | 492.2 |
| Gonorrhea | 127.9 1,477 cases ▼ 33% | 190.2 | 179.5 |
| Syphilis (P&S) | 13.2 153 cases ▼ 19% | 16.3 | 15.8 |
| Syphilis (early) | 9 104 cases ▼ 53% | 19.1 | 16 |
| Syphilis (late/unknown) | 22.3 257 cases ▼ 52% | 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 Contra Costa County, chlamydia has risen from 386.3 to 427.7 per 100,000 (11%), gonorrhea has fallen from 177.7 to 127.9 per 100,000 (28%), and P&S syphilis has fallen from 15.5 to 13.2 per 100,000 (15%).

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 Contra Costa County.
Local HIV snapshot
Contra Costa County HIV care continuum (2023)
Contra Costa County recorded 12.7 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Contra Costa County residents living with HIV, 80.2% are in care · 73.4% 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 Contra Costa County tests for syphilis.

Local resources & officials
Data & references
Local context
Eugene O'Neill National Historic Site sits quietly at Danville's western edge, the kind of landmark that reminds you this town moves at its own deliberate pace. That pace shapes everything, including how residents think about healthcare: most people here own their homes, many have lived on the same street for years, and the social fabric runs through schools, neighborhoods like Alamo Oaks, and commutes up and down I-680 toward the Bay.
What that stability can obscure is that a meaningful share of residents are young adults, people in their late teens and twenties for whom routine STI screening is simply part of staying healthy through the years when new relationships are most common. Danville skews toward long-married households with children at home, which can make sexual health feel like someone else's concern, but younger adults living here or returning after college are navigating those same years regardless of their zip code. With the vast majority of households earning well above six figures, cost alone is rarely the barrier, though the options listed on this page include fee structures that accommodate anyone.
The more practical reality is scheduling. More than six in ten adults are in the workforce, and Contra Costa commutes via I-680 are not short. Several of the options listed here offer extended or flexible hours, so a resident coming off the highway through San Ramon can fit a visit around a commute rather than carving out a separate trip entirely.
Getting there
At 7.18/20 on the EPA walkability index, day-to-day errands in Danville generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
