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.

STD stats & rates
How reported STI rates in Arapahoe County, the county that includes Centennial, 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.
#4 of 64 Colorado counties for chlamydia, a higher rate than 94% of the state
| Infection | Arapahoe County | Colorado | United States |
|---|---|---|---|
| Chlamydia | 528.2 3,465 cases ▲ 21% | 435.1 | 492.2 |
| Gonorrhea | 159.7 1,048 cases ▲ 24% | 128.7 | 179.5 |
| Syphilis (P&S) | 21.2 139 cases ▲ 32% | 16 | 15.8 |
| Syphilis (early) | 12.7 83 cases ▲ 22% | 10.4 | 16 |
| Syphilis (late/unknown) | 29.3 192 cases ▲ 3% | 28.4 | 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 Arapahoe County, chlamydia has fallen from 537.7 to 528.2 per 100,000 (2%), gonorrhea has fallen from 231.7 to 159.7 per 100,000 (31%), and P&S syphilis has risen from 11.1 to 21.2 per 100,000 (91%).

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 Arapahoe County.
Local HIV snapshot
Arapahoe County HIV care continuum (2023)
Arapahoe County recorded 15.3 new HIV diagnoses per 100,000 (2023), against 9.6 statewide and 13.7 nationally. Among Arapahoe County residents living with HIV, 72.9% are in care · 66.8% 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.
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 Arapahoe County tests for syphilis.

Data & references
Local context
Centennial's working families tend to stay put, mortgages, school districts, the kind of stability that builds a neighborhood over decades. That commitment to roots extends to health habits too. Routine STI screening fits naturally into the preventive care that residents already prioritize, whether they're managing young families or building careers. Testing in and around Centennial listed on this page includes walk-in and appointment-based clinics that understand the value of getting results without disruption to a full schedule.
For the young adults moving into or already settled in Centennial, a demographic present across the town's family-centered neighborhoods, confidential screening remains straightforward and accessible. The clinics and urgent-care facilities serving the area treat testing as routine checkup material, not an event requiring elaborate planning or explanation. Results are held securely, and follow-up happens only between you and your provider. Centennial's proximity to both George M.
Wallace Park and the neighborhoods around Palomino Park Resort means that residents rarely need to venture far for care. Whether someone is new to the area or has lived here for years, the testing sites available locally fit the practical rhythm of a community where people manage work, family, and wellness side by side.

Source: Medicare Clinical Laboratory Fee Schedule, CMS, 2025 rates (data.cms.gov). Reference rate for the lab assay only: a clinic visit, sample collection, or a bundled multi-test panel may cost more. Medicaid and most insurers cover STD screening at no out-of-pocket cost.
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.
