Planned Parenthood Mar Monte in Mountain View runs a full gonorrhea, chlamydia, syphilis, herpes, and rapid or conventional HIV panel on sliding-scale fees with no appointment required, same-visit treatment for bacterial infections included, and clinical staff communicate directly in Hindi, Spanish, and Tagalog.
Clinical staff at Planned Parenthood Mar Monte speak Hindi, Spanish, and Tagalog alongside English. Four languages total available for direct clinical conversation. That means medical history, treatment instructions, and prescription guidance are exchanged in the same language across the whole appointment, not relayed through a secondary channel.
As a Title X-funded clinic, Planned Parenthood Mar Monte is legally required to provide confidential family planning services to minors. The confidentiality isn't a clinic-level courtesy but a federal statutory protection. That distinction governs how records are handled and to whom information can be disclosed.
Many sexual health clinics test and treat but stop short of prescribing ongoing HIV prevention, PrEP requires follow-up labs and renewals that get handed off to a primary care provider. Planned Parenthood Mar Monte prescribes and manages both PrEP and PEP directly, including coverage for uninsured patients through dedicated program funding.

Stanford Children's Health in Mountain View brings STI testing through a pediatric and family health system, pairing gonorrhea, chlamydia, syphilis, and HIV screening with sliding-scale fees, same-visit bacterial treatment, and appointment-based access. With interpretation services in Spanish and other languages available throughout.
Stanford Children's Health offers Spanish-language services and broader interpretation support directly within the clinical encounter: meaning the conversation about symptoms, test results, and next steps happens in the language a patient uses, without routing communication through a separate layer.
Without PrEP and PEP available on-site, prevention becomes a separate referral chain. A second clinic, a new intake, a gap before medication starts. Stanford Children's Health in Mountain View manages both, keeping the prescription and the monitoring in the same practice where testing already happens.
Stanford Children's Health tests for seven infections (gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis A, hepatitis B, and hepatitis C) plus TB, giving clinicians a broader baseline from a single visit rather than requiring separate orders at outside labs.

STD stats & rates
How reported STI rates in Santa Clara County, the county that includes Los Altos Hills, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~15% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#36 of 58 California counties for chlamydia, a higher rate than 38% of the state
| Infection | Santa Clara County | California | United States |
|---|---|---|---|
| Chlamydia | 301.8 5,666 cases ▼ 39% | 491.1 | 492.2 |
| Gonorrhea | 110.9 2,083 cases ▼ 42% | 190.2 | 179.5 |
| Syphilis (P&S) | 8.4 157 cases ▼ 48% | 16.3 | 15.8 |
| Syphilis (early) | 10.4 196 cases ▼ 46% | 19.1 | 16 |
| Syphilis (late/unknown) | 29.1 546 cases ▼ 38% | 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 Santa Clara County, chlamydia has risen from 229.4 to 301.8 per 100,000 (32%), gonorrhea has fallen from 117.7 to 110.9 per 100,000 (6%), and P&S syphilis has fallen from 18.3 to 8.4 per 100,000 (54%).

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 Santa Clara County.
Local HIV snapshot
Santa Clara County HIV care continuum (2023)
Santa Clara County recorded 10.3 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Santa Clara County residents living with HIV, 77.4% are in care · 70.1% 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 Santa Clara County tests for syphilis.

Local resources & officials
Data & references
Local context
Foothill Expressway threads quietly past properties where ownership runs deep and long: the kind of town where people don't move often, and the community fabric reflects that stability. Los Altos Hills carries a settled character that shows up in its household structure too: most adults here are married, living in full households, and the labor-force participation rate reflects a community with a significant share of people outside traditional nine-to-five employment: retired professionals, stay-at-home parents, or those whose wealth allows flexibility in how they structure their days. That stability, though, can make the logistics of sexual health screening feel oddly out of step. Younger adults here (people in their late teens and twenties, the years when STI transmission is highest) represent a relatively small slice of the population, which can mean fewer peers normalizing routine testing.
When most of the community isn't cycling through the same life stage, the social cues that make screening feel ordinary elsewhere are quieter here. Meanwhile, high housing costs mean that even the renters who do live here carry real financial pressure, and for anyone balancing cost alongside an already thin peer culture around testing, scheduling can simply fall away. The clinics listed on this page include options reachable via I-280 and South San Antonio Road, offering range across schedules and fee structures, so the Paul Shoup House end of town and the Castro City corridor both have workable routes to care.

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.
