Sun River Health in Greenport tests for HIV, gonorrhea, chlamydia, syphilis, herpes, hepatitis A, B, and C, and TB. With same-visit treatment for bacterial infections. Fees slide to income, and appointments are required. Staff communicate directly in ASL and Spanish.
Many clinics rely entirely on outside interpretation services, leaving patients to navigate sensitive conversations through a third layer of communication. Sun River Health carries ASL and Spanish fluency within the practice itself, and extends interpretation access to other languages, so the conversation about your sexual health stays direct and complete.
Sun River Health prescribes and manages both PrEP and PEP on-site, which means prevention isn't a separate errand across town: your testing, your risk conversation, and your prescription happen within the same clinical relationship.
For anyone without a regular specialist, or paying out of pocket, the distance between a hepatitis C diagnosis and actual antiviral treatment can stretch into months. Sun River Health closes that gap: diagnosis and on-site treatment are both available, so the medication follow-through doesn't require finding a separate provider.

Northwell Health-GoHealth Urgent Care in Bridgehampton takes walk-ins for a full STI panel (HIV, syphilis, gonorrhea, chlamydia, herpes, hepatitis A, B, and C, plus TB) with same-visit treatment for bacterial infections, HPV and hepatitis vaccines, and sliding-scale fees accepted alongside insurance and Medicaid.
The panel at Northwell Health-GoHealth Urgent Care extends to herpes simplex and all three hepatitis strains (A, B, and C) alongside the standard bacterial and HIV tests. That range means a single visit produces answers on infections that a narrower panel would leave unaddressed entirely.
Interpretation services for non-English languages are available at this Bridgehampton clinic, which means results, treatment instructions, and prevention guidance reach patients in the language they actually use to make decisions about their care.

STD stats & rates
How reported STI rates in Suffolk County, the county that includes Dering Harbor, compare with New York and U.S. averages, based on the most recent 2023 surveillance data.
#19 of 62 New York counties for chlamydia, a higher rate than 69% of the state
| Infection | Suffolk County | New York | United States |
|---|---|---|---|
| Chlamydia | 342.5 5,217 cases ▼ 39% | 558.4 | 492.2 |
| Gonorrhea | 70.5 1,074 cases ▼ 70% | 235.6 | 179.5 |
| Syphilis (P&S) | 5.8 89 cases ▼ 61% | 14.8 | 15.8 |
| Syphilis (early) | 11 167 cases ▼ 52% | 23.1 | 16 |
| Syphilis (late/unknown) | 10.4 159 cases ▼ 59% | 25.2 | 29.5 |
Rates per 100,000 population, 2023. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis). Population figures: U.S. Census Bureau ACS. These figures are the latest available surveillance estimates. Bars are scaled to the highest rate shown.
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 Suffolk County, chlamydia has risen from 314.4 to 342.5 per 100,000 (9%), gonorrhea has risen from 69.3 to 70.5 per 100,000 (2%), and P&S syphilis has risen from 3.9 to 5.8 per 100,000 (49%).
The 2020 dip reflects reduced pandemic-era screening, not lower transmission. Source: CDC NCHHSTP AtlasPlus (county, state & U.S., all-ages basis).
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 Suffolk County.
Local HIV snapshot
Suffolk County HIV care continuum (2023)
Suffolk County recorded 6.2 new HIV diagnoses per 100,000 (2023), against 14.1 statewide and 13.7 nationally. Among Suffolk County residents living with HIV, 82.4% are in care · 77.3% 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 Suffolk County tests for syphilis.

Data & references
Local context
A weekday trip to pick up groceries or mail often means crossing paths with neighbors on Clinton Avenue or near Shelter Island's ferry routes, the kind of visibility that makes private health decisions feel more complicated than they should. STI testing in and around Dering Harbor reflects that reality: people here need screening that doesn't broadcast itself, and the clinics listed on this page understand why discretion matters in a place where word travels fast. Young adults in their late teens through thirties make up a meaningful part of Dering Harbor's year-round and seasonal population. For this group, routine confidential screening is straightforward medical sense, not a crisis response.
Testing happens without fanfare: results are yours alone, and no one at the clinic phones ahead or leaves traces on a shared family insurance statement if you arrange it differently. The testing available in and around Dering Harbor covers the full range of what people need to know about their sexual health. Whether you're establishing baseline status, following up after a partner's diagnosis, or screening as part of regular care, the providers here handle these visits as routine. Finding a time that fits your schedule, whether that's a weekday morning before work or a quieter afternoon, keeps the whole process low-key and yours to manage.
Getting there

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