Mountain Family Health Centers in Glenwood Springs runs STI care on a sliding-scale fee open to everyone, accepting Medicaid, Medicare, and private insurance. The family practice tests for gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis A and B, and TB, by appointment, with same-visit treatment for bacterial infections and PrEP and PEP on-site.
Mountain Family Health Centers prescribes both PrEP and PEP from within the same family practice setting where patients manage everything else: meaning prevention doesn't require a separate specialty referral, and staying consistent with a PrEP regimen gets folded into routine care.
Many clinics cap their panel at gonorrhea, chlamydia, syphilis, and HIV and leave herpes and hepatitis testing for elsewhere. Mountain Family Health Centers tests for herpes, hepatitis A, and hepatitis B alongside the core panel, so a single appointment covers infections that often go unexamined.

STD stats & rates
How reported STI rates in Garfield County, the county that includes New Castle, compare with Colorado and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~23% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#10 of 64 Colorado counties for chlamydia, a higher rate than 84% of the state
| Infection | Garfield County | Colorado | United States |
|---|---|---|---|
| Chlamydia | 413 259 cases ▼ 5% | 435.1 | 492.2 |
| Gonorrhea | 41.5 26 cases ▼ 68% | 128.7 | 179.5 |
| Syphilis (P&S) | 8 5 cases ▼ 50% | 16 | 15.8 |
| Syphilis (early) | 8 5 cases ▼ 23% | 10.4 | 16 |
| Syphilis (late/unknown) | 11.2 7 cases ▼ 61% | 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 Garfield County, chlamydia has risen from 282.1 to 413 per 100,000 (46%), gonorrhea has fallen from 81.1 to 41.5 per 100,000 (49%), and P&S syphilis has risen from 3.2 to 8 per 100,000 (150%).

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 Garfield County.
Local HIV snapshot
Garfield County HIV care continuum (2021)
Garfield County recorded 9.8 new HIV diagnoses per 100,000 (2021), against 9.6 statewide and 13.7 nationally. Among Garfield County residents living with HIV, 72.8% are in care · 64.2% 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 Garfield County tests for syphilis.

Data & references
Local context
New Castle wears a settled look (high homeownership, most households built around families) but the logistics of getting a routine STI screen here are genuinely less convenient than that stability suggests. That planning matters most for younger residents, people in their late teens and twenties who are statistically at the sharpest end of STI risk. With nearly half of New Castle households clearing six figures and labor-force participation running high, the challenge here isn't usually cost awareness; it's the compressed schedule that comes with full employment and larger-than-average households. When both partners work and kids are in the picture, carving out time to drive somewhere along West Main Street and back is the real obstacle, not the intention to go.
The testing options listed on this page exist precisely for that kind of calendar. Some offer hours outside the standard workday; others serve patients on a sliding scale for the roughly one-in-four households that aren't in that higher-earning tier. Knowing which clinic sits closest to your end of US 6, and whether it takes walk-ins on a Thursday evening, is the kind of detail that actually changes whether the appointment gets made before summer at Bear Dance Park turns into a busy fall.
Getting there
At 6.42/20 on the EPA walkability index, day-to-day errands in New Castle generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
