Founders Family Medicine and Urgent Care in Castle Rock tests for gonorrhea, chlamydia, HIV, and hepatitis A, B, and C, treating any bacterial STI the same visit: with sliding-scale fees that apply to everyone, and all services available at no fee.
For anyone paying out of pocket (no insurance, no regular provider, no employer coverage) Founders Family Medicine and Urgent Care covers the full cost of every service it offers. Testing, vaccination, and treatment are each available at no charge, with sliding-scale fees as the floor and zero as the ceiling.
Clinics running a standard STI panel typically stop at HIV, gonorrhea, chlamydia, and syphilis. Leaving hepatitis for a separate appointment elsewhere. Founders tests for hepatitis A, B, and C alongside conventional HIV testing, so a single visit covers infections that share transmission routes but rarely share a testing room.

Planned Parenthood of the Rocky Mountains in Greenwood Village takes walk-ins for STI testing (HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis A, B, and C) with same-visit treatment for bacterial infections, sliding-scale fees, and staff who communicate in American Sign Language and Spanish.
Planned Parenthood of the Rocky Mountains in Greenwood Village has staff who communicate in American Sign Language and Spanish, with interpretation available for other languages, which means Deaf patients and non-English speakers get clinical conversations conducted in their own language, not mediated through workarounds.
Many family planning providers leave minors reliant on a parent's coverage and the privacy exposure that comes with it. As a Title X clinic, Planned Parenthood of the Rocky Mountains in Greenwood Village provides legally confidential services to minors: meaning the visit, the test, and any treatment stay off a guardian's insurance explanation of benefits by law.
Planned Parenthood of the Rocky Mountains in Greenwood Village prescribes PrEP, PEP, and DoxyPEP directly, so patients leave with an actual prevention regimen rather than a name to look up, and PrEP is available at no cost for those without insurance.

University of Colorado in Aurora operates on a sliding-scale fee structure and accepts Medicaid, Medicare, and private insurance, making its full panel (gonorrhea, chlamydia, syphilis, conventional HIV, and hepatitis C) available at appointment-based visits with same-visit treatment for bacterial STIs.
University of Colorado carries both PrEP and PEP as standing clinical services, which means prevention medication can be initiated and managed without routing through a separate provider. That continuity keeps the gap between a conversation and an actual prescription as short as possible.
For anyone without a regular primary care provider, or paying on the sliding scale and consolidating visits where they can, University of Colorado tests hepatitis C alongside gonorrhea, chlamydia, syphilis, and HIV in a single appointment. That breadth means a more complete picture of blood-borne and sexually transmitted risk from one place.

UCHealth in Aurora pairs bacterial STI testing (gonorrhea, chlamydia, syphilis) with same-visit treatment when results call for it, all on a fee schedule that accepts Medicaid, Medicare, and private insurance. Appointments are required, and care is available in Spanish.
When a language gap means a question goes unasked or an instruction goes ununderstood, the downstream cost is a missed dose, a delayed diagnosis, or a partner not notified. At UCHealth Aurora, Spanish-language care is built into the clinical encounter itself, not sourced afterward, so nothing critical waits on a workaround.
UCHealth Aurora prescribes both PrEP and PEP directly, which means a patient who qualifies can leave with an active prevention plan rather than a name to look up elsewhere. That continuity keeps adherence, and therefore effectiveness, grounded in an established clinical relationship.
For anyone without a regular provider, or paying out of pocket and wanting answers in a single visit, UCHealth Aurora's panel extends to herpes, hepatitis A, B, and C alongside the core bacterial and HIV tests, eliminating the need to piece together screening across multiple appointments.

Arapahoe County Public Health in Englewood tests for HIV, hepatitis C, syphilis, gonorrhea, and chlamydia (all at no charge, on a sliding scale) with same-visit treatment for bacterial infections and appointments required for scheduled care.
Fee-waived STI testing is common enough, but many clinics apply charges the moment care moves beyond the test itself. A vaccine, a treatment visit, a counseling session. At Arapahoe County Public Health, the no-fee policy holds across the board: testing, treatment, vaccines, and prevention services alike.
Arapahoe County Public Health maintains on-staff Spanish-language capability alongside broader interpretation services: meaning a conversation about PrEP, medication adherence, or a new diagnosis unfolds with full fluency rather than pauses and workarounds. That standing capacity is what makes follow-through on treatment plans realistic.
The clinic prescribes and manages all three preventive regimens (daily PrEP for HIV, PEP for post-exposure HIV prevention, and DoxyPEP for bacterial STI prevention) with medication adherence education built into the visit rather than handed off. Ongoing monitoring for PrEP, including required labs, is handled within the same clinical relationship.

STD stats & rates
How reported STI rates in Douglas County, the county that includes Castle Pines, compare with Colorado and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~22% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#43 of 64 Colorado counties for chlamydia, a higher rate than 33% of the state
| Infection | Douglas County | Colorado | United States |
|---|---|---|---|
| Chlamydia | 186.8 717 cases ▼ 57% | 435.1 | 492.2 |
| Gonorrhea | 39.9 153 cases ▼ 69% | 128.7 | 179.5 |
| Syphilis (P&S) | 4.2 16 cases ▼ 74% | 16 | 15.8 |
| Syphilis (early) | 1.8 7 cases ▼ 83% | 10.4 | 16 |

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 Douglas County, chlamydia has fallen from 210.9 to 186.8 per 100,000 (11%), gonorrhea has fallen from 43.6 to 39.9 per 100,000 (8%), and P&S syphilis has risen from 3.9 to 4.2 per 100,000 (8%).

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 Douglas County.
Local HIV snapshot
Douglas County HIV care continuum (2023)
Douglas County recorded 3.4 new HIV diagnoses per 100,000 (2023), against 9.6 statewide and 13.7 nationally. Among Douglas County residents living with HIV, 81% are in care · 76.3% 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 Douglas County tests for syphilis.

Data & references
Local context
Happy Canyon Ranches sits at the comfortable end of Castle Pines, where the lots are generous and nearly nine in ten households own their home outright. That deep ownership stake, paired with the fact that nearly three-quarters of households here earn well above six figures, shapes how residents think about health costs: most carry coverage, most have a regular doctor, and routine care rarely feels out of reach in the abstract. But the young adults in their late teens and twenties who live here, whether they're renting one of the relatively scarce apartments near Silver Heights or still living at home in a large family household, often defer screening simply because it requires a deliberate trip, not because it's unaffordable.
That trip matters in Castle Pines specifically. The city sits away from the clinical corridors of the Denver metro, so the options listed on this page involve a real drive rather than a quick errand on the way home from work. With the labor-force participation rate reflecting a community where most adults are working full schedules, carving out a weekday window takes actual planning, and weekend or extended-hours slots at the listed sites make the difference for working adults.
Douglas County's STI trends are visible on this page, and the under-35 population here, modest in share but concentrated in active social years, is the group those trends most directly concern. Knowing which listed site has Saturday hours before you need one is the practical move Castle Pines' schedule tends to reward.
Getting there

Two things that actually depend on Colorado 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 Colorado, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Colorado 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.
