How to read these listings
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.

Every Service Here Runs at Zero Cost
Title X funding drives the fee structure to zero across the entire menu: testing, PrEP prescriptions, DoxyPEP, mpox vaccine, HPV vaccine, hepatitis A and B vaccines, STI treatment. That floor applies to every service, not a selected subset, so no single line item carries a charge that others don't.
Spanish Spoken On-Site, Interpretation Beyond That
Spanish is a native clinical language at this Pasadena location, handled by staff rather than routed through an external service. For other languages, interpretation is available on-site, meaning the same zero-cost, full-panel care is accessible without language acting as a barrier to any service.
Title X Confidentiality Extends to Minors
As a Title X-funded clinic, Planned Parenthood Pasadena and San Gabriel Valley is legally required to keep family planning services, including STI testing and treatment, confidential for minors, independent of parental insurance or consent. That federal protection is structural, not discretionary, and applies to the full scope of Title X services offered.

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.

Los Angeles County HIV care continuum (2023)
Los Angeles County recorded 19.6 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Los Angeles County residents living with HIV, 91.6% know their status · 72.8% are in care · 65.2% 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.
Pregnant or planning to be?Congenital syphilis is the fastest-rising STI: what to test, and when
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 Los Angeles County tests for syphilis.

Chapman Woods sits at the quieter eastern edge of Sierra Madre, where wide lots and mature trees give the neighborhood a settled, almost unhurried feel. More than half of residents here own their homes, many of them families sharing households of three or more, and a majority of adults are married, which shapes a community that can look stable from the outside but still carries the full range of sexual health needs that any mixed-age population does. Rent runs well above fifteen hundred dollars a month for those who don't own, and with unemployment running meaningfully above the state's comfort zone, a co-pay or an unexpected lab bill can genuinely tip the decision not to get tested at all.
Young adults in their late teens and twenties make up a smaller slice of Sierra Madre than they do in denser cities nearby, but that age group nationally accounts for the overwhelming share of chlamydia and gonorrhea diagnoses, and Los Angeles County's STI rates make that worth taking seriously here too. For someone working one of the jobs that anchors the local labor force, carving out a weekday appointment takes real coordination, especially when the nearest options listed on this page may require a drive out along Foothill Boulevard or East Sierra Madre Boulevard toward Monrovia or beyond.
Sierra Vista Park sits close to the heart of town, and a clinic listed here that falls along that same eastern corridor is worth identifying now, before a lapse in coverage or a change in partners makes the question feel more urgent.

Confidentiality & consent in CaliforniaMinor consent and partner treatment (EPT) under state law, plus how to test privately
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).
Can a minor consent on their own?
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
Can my partner be treated too? (EPT)
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.
