No Fee Applies to Every Service Here
For anyone without a regular provider, paying out of pocket, or simply stretched thin, the Free Clinic of Simi Valley's zero-fee model covers the full visit (testing, diagnosis, and treatment) without a bill at the end. Donations are welcome but never required.
Spanish Spoken Directly, Not Routed Through a Line
Many clinics handle Spanish speakers through a remote service rather than staff who work in the language directly. At Free Clinic of Simi Valley, Spanish-language care is delivered on-site, so the conversation about symptoms, treatment, and follow-up happens without an intermediary in the room.

Clinicas del Camino Real in Simi Valley requires an appointment and covers gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis C, and TB in a single visit, with same-visit treatment for bacterial infections, sliding-scale fees accepted by all, and HPV, hepatitis A, and hepatitis B vaccines on-site. With full services in Spanish.

Herpes and Hepatitis C Diagnosed Here, Not Later
Leaving herpes or hepatitis C off a panel means a second appointment elsewhere, another fee, and a gap before treatment begins. Clinicas del Camino Real tests for both on the same visit as the core bacterial panel, so a complete picture, and a path to managing hepatitis C, comes from one appointment, not two.
Spanish-Language Care Without a Workaround
Spanish-speaking patients navigating STI care without a regular provider often absorb extra friction, appointments delayed by language barriers, details lost in translation mid-visit. Clinicas del Camino Real delivers the full appointment, counseling, and treatment conversation in Spanish as a standing clinical capability, not a patched-in accommodation.

Carbon Health in Moorpark is a walk-in urgent and primary care clinic that folds STI testing (gonorrhea, chlamydia, HIV, hepatitis, herpes, and TB) into its standard visit model, with insurance accepted and same-visit bacterial treatment available. PrEP and PEP are both prescribed on-site.

Prevention Prescriptions Written Here, Not Forwarded
Walk-in STI clinics routinely handle testing but stop short of writing HIV prevention prescriptions, leaving patients to track down a separate provider. Carbon Health closes that gap, both PrEP for ongoing prevention and PEP are prescribed and managed directly by its clinical team in Moorpark.
Herpes and Hepatitis Testing Alongside the Core Panel
Carbon Health runs blood and swab work for herpes simplex and all three hepatitis strains (A, B, and C) in addition to gonorrhea, chlamydia, and HIV. That means a single visit in Moorpark can generate results across infections that would otherwise require separate orders at separate facilities.

Moorpark Family Medical Clinic in Moorpark welcomes patients without an appointment, so a single walk-in visit can cover sliding-scale STI screening for syphilis, gonorrhea, and chlamydia.

Spanish Is a Working Clinical Language Here
Spanish is a full clinical language at Carbon Health: not a supplemental accommodation but the language in which providers explain dosing instructions, PrEP adherence schedules, and hepatitis treatment plans. For patients who navigate medical decisions in Spanish, that means nothing is lost between the exam room and the prescription.
PrEP, PEP, and DoxyPEP Prescribed from One Practice
Carbon Health carries standing prescribing capability for PrEP, PEP, and DoxyPEP. The full current toolkit for HIV and bacterial STI prevention. Someone without a dedicated infectious-disease provider, or paying out of pocket without an established specialist, can access all three here without coordinating across multiple practices.
Hepatitis C Antiviral Treatment Managed On-Site
Carbon Health prescribes and monitors direct-acting antiviral therapy for hepatitis C internally: meaning the provider ordering the confirmatory RNA test is also the one initiating treatment and tracking viral-load response across the cure course, rather than handing that management to a separate gastroenterology or hepatology referral.
Optum in West Hills runs by appointment, so scheduling ahead unlocks a visit that covers the standard panel (HIV, syphilis, gonorrhea, chlamydia) plus hepatitis A, B, and C testing, with bacterial STIs treated same-day and fees scaled to income. PrEP and PEP are prescribed on-site.
Read full overviewShow less
PrEP and PEP Prescribed at the Same Visit
Optum writes PrEP and PEP prescriptions directly, so a prevention plan comes out of the same appointment as testing. That means ongoing PrEP follow-up (labs, refills, monitoring) stays with one clinical team rather than splitting across providers.
Hepatitis C Treated Here, Not Handed Off
When a hepatitis C diagnosis goes unmanaged, the gap between a positive antibody result and actual treatment can stretch into months of delays, extra specialist appointments, and additional costs. Optum closes that gap by treating hepatitis C on-site, diagnosis and antiviral management handled by the same clinic.
Hepatitis Screening Included in the Standing Panel
For anyone without a regular primary care provider, or paying out of pocket and wanting to consolidate visits, Optum's panel covers hepatitis A, B, and C alongside the core bacterial and viral STI tests, meaning one appointment accounts for infections that a narrower clinic would require a separate lab order to catch.

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.

Among Ventura County residents living with HIV, 76.6% are in care · 63.7% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.

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 Ventura County tests for syphilis.

Simi Valley's name echoes the Chumash word "Simiji," a nod to the valley's indigenous past before it became the bedroom community it is today. A place where families plant themselves for decades. The town's stability attracts homeowners who build lives here across generations, and that rootedness extends to how residents approach their health. STI testing in and around Simi Valley reflects the practical needs of a population that values discretion alongside access: screening happens quietly, results stay confidential, and the clinics listed on this page understand that people testing here often juggle work, school, and household responsibilities. Young adults across Simi Valley, from the Greek Tract neighborhoods to areas near Rancho Tapo Community Park, benefit from straightforward testing that fits into busy schedules.
Routine screening matters most in your twenties and thirties, when many people are navigating new relationships or simply want baseline peace of mind. The testing sites available locally do not flag results to employers, schools, or family members; what you learn stays between you and your provider. Testing is not a rare event in Simi Valley; it is a normal part of how thoughtful residents care for themselves. Whether you grew up here or moved to plant roots, the clinics and urgent care facilities listed on this page offer the same confidentiality and straightforward service they provide to thousands of others in the valley each year.

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.
