Available testing centers
12 testing options are listed for Windsor, CO. The nearest, Sunrise Community Health, is about 0.7 miles away. Compare community and public clinics, private labs, and at-home kits below.
Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Sunrise Community Health in Windsor tests for gonorrhea, chlamydia, syphilis, herpes, hepatitis B and C, and HIV. With same-visit treatment for bacterial infections on a sliding-scale fee open to all. Appointments are required, and Spanish-language care is available throughout.
Spanish at Sunrise Community Health is not limited to check-in paperwork: it carries through counseling, test results, and treatment planning. That continuity means a patient's understanding of a diagnosis, a drug regimen, or a prevention option isn't filtered through translation gaps at any point in the visit.
Beyond the core four, Sunrise tests for herpes, hepatitis B, and hepatitis C. Meaning infections that often surface without obvious symptoms get caught in the same appointment. For hepatitis B in particular, that result feeds directly into the clinic's vaccination program if immunity isn't present.

UCHealth in Loveland runs on appointments and covers gonorrhea, chlamydia, syphilis, hepatitis B and C, and HIV, with same-visit treatment for bacterial infections, on a fee structure that accepts Medicaid, Medicare, and private insurance.
Sexual health clinics that stop at testing leave patients to seek prevention prescriptions elsewhere. UCHealth prescribes both PrEP and PEP on-site in Loveland, keeping the path from testing to ongoing prevention contained within a single clinical relationship.
UCHealth treats hepatitis C on-site in Loveland rather than stopping at diagnosis, which means a positive result doesn't reset the clock while a patient waits to establish care with a separate specialist.
UCHealth's panel in Loveland folds hepatitis B and C testing alongside the core bacterial and HIV screen, so infections that often go undetected surface during the same visit rather than requiring a separate appointment.

North Loveland Community Health Center, in Loveland, anchors its STI care in a sliding-scale fee structure tied to income. No one is turned away for inability to pay. Walk-ins are welcome for screening that covers syphilis, gonorrhea, and chlamydia under its federally qualified health center standing.

Larimer County Department of Health and Environment in Loveland runs entirely on a no-cost model (every service, every time) while covering gonorrhea, chlamydia, syphilis, and HIV on a sliding scale with Medicaid accepted. Appointments are required.
Plenty of public health clinics post a sliding scale and leave certain services outside it, a vaccine here, a treatment visit there, priced separately. At Larimer County Department of Health and Environment, the fee structure is flat: nothing costs anything, full stop, across testing, treatment, vaccines, and counseling alike.
When a clinic lacks Spanish-language capacity, the real cost isn't inconvenience. It's a delayed diagnosis, an untreated infection, a treatment plan that never quite landed. Larimer County Department of Health and Environment delivers STI care, counseling, and treatment directly in Spanish, keeping the entire clinical conversation inside this office.

South Loveland Community Health Center in Loveland welcomes walk-ins for STI screening, no appointment needed.

Planned Parenthood of the Rocky Mountains in Greeley runs on a sliding-scale fee structure and accepts Medicaid and private insurance, covering gonorrhea, chlamydia, syphilis, herpes, and rapid and conventional HIV testing. Appointment required, with same-visit treatment for bacterial infections.
Plenty of clinics test for gonorrhea, chlamydia, syphilis, and HIV and leave it there: herpes requires a separate trip, a separate provider, or simply goes untested. Planned Parenthood of the Rocky Mountains in Greeley includes herpes in its panel, closing that gap in a single appointment.
Title X designation gives Planned Parenthood of the Rocky Mountains in Greeley the standing to provide legally confidential services to minors, no parental billing trail, no insurance disclosure. For a young person without a regular provider or paying out of pocket, that legal protection is the difference between getting tested and not.
When Spanish isn't available in the exam room itself, the care suffers: nuances in symptoms get lost, questions go unasked, and follow-through drops. At Planned Parenthood of the Rocky Mountains in Greeley, Spanish-language care and broader interpretation services are part of the clinical encounter, not a workaround bolted onto it.

Weld County Department of Public Health and Environment in Greeley tests for HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis C, and TB, treating bacterial infections the same visit. Sliding-scale fees apply, and all services are provided at no fee.
For anyone paying cash, without a regular provider, or stretching a tight budget, Weld County Public Health's standing policy is straightforward: every service (testing, treatment, vaccines, PrEP) is provided at no fee. That coverage extends to the full visit, not a selected tier of it.
Many clinics handle non-English speakers reactively, with whatever workaround is available that day. Weld County Public Health in Greeley offers Spanish-language services and interpretation for other languages as a built-in appointment feature, so clinical conversations don't get compressed or lost in the middle.
Weld County Public Health carries both PrEP and PEP, and PrEP costs are explicitly covered for uninsured patients. Meaning the medication, not just the counseling, is financially accessible. That makes ongoing HIV prevention sustainable rather than dependent on finding outside coverage.

Colorado Health Network in Fort Collins runs appointments for rapid HIV, hepatitis C, gonorrhea, and chlamydia testing, with same-visit treatment for bacterial infections, on a sliding scale that extends to fully covered care for those who qualify.
Colorado Health Network draws on Medicaid billing, insurance reimbursement, and grant-funded coverage to zero out the cost for patients who qualify. Meaning the sliding scale bottoms out at nothing, sustained by actual payer relationships rather than a waived line item.
Care at Colorado Health Network in Fort Collins is available fully in Spanish, which means a patient's results, risk conversation, and any prescription are handled in Spanish directly. Not reconstructed afterward.
Many prevention-focused clinics prescribe PrEP and leave it there; Colorado Health Network in Fort Collins also prescribes DoxyPEP, the post-exposure antibiotic protocol for bacterial STI prevention, giving patients access to three distinct prevention tools from a single clinical relationship.

STD stats & rates
How reported STI rates in Weld County, the county that includes Windsor, 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.
#17 of 64 Colorado counties for chlamydia, a higher rate than 73% of the state
| Infection | Weld County | Colorado | United States |
|---|---|---|---|
| Chlamydia | 343.3 1,234 cases ▼ 21% | 435.1 | 492.2 |
| Gonorrhea | 66.5 239 cases ▼ 48% | 128.7 | 179.5 |
| Syphilis (P&S) | 6.1 22 cases ▼ 62% | 16 | 15.8 |
| Syphilis (early) | 3.9 14 cases ▼ 62% | 10.4 | 16 |
| Syphilis (late/unknown) | 10.9 39 cases ▼ 62% | 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 Weld County, chlamydia has fallen from 417 to 343.3 per 100,000 (18%), gonorrhea has fallen from 126.5 to 66.5 per 100,000 (47%), and P&S syphilis has risen from 4 to 6.1 per 100,000 (52%).

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 Weld County.
Local HIV snapshot
Weld County HIV care continuum (2023)
Weld County recorded 5.8 new HIV diagnoses per 100,000 (2023), against 9.6 statewide and 13.7 nationally. Among Weld County residents living with HIV, 77.2% are in care · 70.5% 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 Weld County tests for syphilis.

Data & references
Local context
Covenant Park sits near the center of Windsor in the kind of settled quiet that comes from a town where most households own their homes and nearly two-thirds of adults are married, raising families that average more than three people each. That stability shapes daily life here in real ways, including how people schedule the things they keep meaning to get around to, like STI screening.
The logistics underneath that calm take some planning. CO 392 carries Windsor residents toward the nearest testing options listed on this page, and depending on where you live, that trip through Weld County is a genuine commitment of time, not a quick errand. For the younger adults in their late teens and twenties who make up a meaningful slice of Windsor's population, and who face the years when chlamydia and gonorrhea rates climb, a multi-step trip on a weekday is easier to postpone than to make. Knowing exactly which options listed here keep evening or weekend hours before you need them removes at least one reason to wait.
Cost is its own consideration. Close to half of Windsor households earn six figures, but that share also means a real portion of residents do not, and rent averaging over twelve hundred dollars a month leaves less cushion than home values suggest. For a renting family in Highland Hills without employer-sponsored coverage, the sliding-scale or no-cost options listed on this page are the ones worth calling first.
Getting there
At 7.85/20 on the EPA walkability index, day-to-day errands in Windsor generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
