Rated 4.2 out of 5 from 15 reviews

AltaMed Medical Group in Anaheim is a full medical clinic where a positive gonorrhea or chlamydia result can be treated the same visit, no separate appointment, no delay. The standard panel covers HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis C, and TB on a sliding-scale fee, and every STI and HIV test is free.

Read full overview

Every Service Carries a Zero Balance

When a single unexpected bill is enough to delay follow-up care (the specialist visit, the hepatitis C treatment, the PrEP prescription) cost becomes its own medical risk. At AltaMed Anaheim, every service is provided at no fee, so a reactive hepatitis C result moves to on-site treatment without a financial barrier interrupting the chain.

Spanish Spoken Natively, Not Through a Workaround

Many clinics handle Spanish by routing communication through an add-on service, accurate enough for logistics, but flattening for anything nuanced. AltaMed Anaheim delivers care directly in Spanish, which means a conversation about PrEP adherence or a positive syphilis result happens in full, not in approximation.

PrEP and PEP Prescribed and Monitored On-Site

AltaMed Anaheim handles the full PrEP cycle internally: initial HIV and renal labs, prescription, and the every-three-month monitoring visits required to keep the prescription active. PEP is also available and managed by the same clinical staff, meaning neither prevention medication requires a separate prescriber or outside coordination.

Rated 3.6 out of 5 from 100 reviews

Planned Parenthood of Orange and San Bernardino Counties in Anaheim runs appointment-based STI care (rapid HIV, gonorrhea, chlamydia, syphilis, and herpes testing) on a sliding-scale fee accepted alongside Medicaid and insurance, with same-visit treatment for bacterial infections and Spanish-language and interpretation services on hand.

Read full overview

Spanish and Interpretation Serve Every Appointment

Planned Parenthood Anaheim holds Spanish-speaking staff and interpretation services as a standing part of every appointment, not an add-on to request. For anyone who navigates medical decisions more precisely in a language other than English, that capability means STI counseling, treatment decisions, and PrEP conversations all happen without a linguistic gap in the room.

Minor-Confidential Services Are Rarely This Complete

Few STI clinics carry Title X designation, which legally guarantees confidential family planning services for minors: meaning a young person's visit, results, and care decisions are not disclosed to a parent or guardian. Planned Parenthood Anaheim holds that designation, making it one of the few places a minor can access the full continuum from testing to treatment to contraception under a single protected visit.

DoxyPEP Alongside PrEP Expands the Prevention Toolkit

Doxycycline post-exposure prophylaxis, DoxyPEP, reduces bacterial STI risk when taken after a potential exposure, and Planned Parenthood Anaheim prescribes it alongside both PrEP and PEP. Having all three prevention medications available at one clinic means a patient's prevention strategy can be calibrated precisely, without splitting prescriptions across separate providers.

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.

Orange County recorded 9.7 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Orange County residents living with HIV, 80.3% know their status · 71.3% are in care · 64.8% 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 Orange County tests for syphilis.

Local context

About Placentia, CA

A trip to Old Town Placentia for coffee or errands brings you past neighbors' familiar houses and the same storefronts, the kind of place where people notice who's coming and going. That visibility, combined with the fact that many households span generations under one roof, can make seeking STI testing feel like something best handled away from the local gaze. The clinics and providers listed on this page serve Placentia and surrounding areas with the understanding that confidentiality isn't negotiable; what you discuss with a clinician stays confidential by law, regardless of how well-known you are around town. Young adults in Placentia (whether newly working, in school, or building their first household) often have sex lives that don't align with the pace of small-town social memory.

Routine screening catches infections early, before symptoms emerge, and gives you medical facts rather than worry. Testing is straightforward and usually quick. The providers available in and around Placentia include both walk-in clinics and appointment-based services; some offer rapid results, others mail them securely. Whether you've been with one partner or several, or simply want baseline peace of mind, you can arrange testing on your own timeline without explaining yourself to anyone in your orbit.

Confidentiality & consent in California Minor 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.
