Stony Brook Adolescent Medicine in Lake Grove covers the full bacterial and viral panel (gonorrhea, chlamydia, syphilis, hepatitis A, B, and C, herpes, TB, and HIV) treats bacterial infections the same visit, and runs everything on a sliding scale, by appointment.
A co-pay that stops someone from picking up a prescription, a lab bill that follows a visit weeks later. Those gaps let treatable conditions go untreated. At Stony Brook Adolescent Medicine, no service at this clinic generates a charge, so cost never becomes the reason care stalls.
Stony Brook Adolescent Medicine provides clinical care entirely in Spanish, not a support function layered on top, but the actual medical conversation. For someone navigating PrEP adherence, hepatitis B treatment, or an ongoing HIV regimen without a regular English-speaking provider, that fluency shapes whether a care plan actually holds.
Ryan White funding at Stony Brook Adolescent Medicine supports the full arc of HIV care (rapid and conventional testing, medical treatment, and medication adherence counseling) which means a patient's relationship with this clinic doesn't reset each time the clinical need deepens.

Stony Brook Medicine in Stony Brook runs STI care by appointment, with each visit covering gonorrhea, chlamydia, syphilis, herpes, hepatitis A, B, and C, TB, and rapid or conventional HIV testing on a sliding-scale fee, bacterial infections treated the same day, with care available in Spanish.
Plenty of STI clinics run a hepatitis C antibody test and leave the next step to the patient to sort out independently. Stony Brook Medicine treats hepatitis C on-site, so a confirmed diagnosis moves directly into a treatment plan, managed by the same clinical team that caught it.
PrEP at Stony Brook Medicine means a prescription for daily antiretroviral medication paired with scheduled follow-up visits for HIV testing, kidney function monitoring, and adherence support. Not a one-time handoff. PEP is similarly prescribed and clinically tracked through the full course of treatment.
Without Spanish-language clinical care, a patient navigates diagnosis, treatment decisions, and medication instructions across a language barrier, and the resulting gaps can leave infections untreated or poorly managed. Stony Brook Medicine delivers that care directly in Spanish, keeping every step of the clinical conversation in the room.

STD stats & rates
How reported STI rates in Suffolk County, the county that includes Head of the Harbor, compare with New York 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.
#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 |

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%).

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
Stony Brook Grist Mill sits at the kind of corner that makes Head Of The Harbor feel as though it has barely moved in decades, owner-occupied homes lining the roads off NY 25A, households that have largely settled in rather than passing through. That stability shapes the community in real ways: with nearly three in four households above the six-figure income threshold and a majority of adults partnered and living in larger family units, the social texture here leans toward the established rather than the transient. Yet quieter places can make routine health maintenance feel like an afterthought, and the roughly one-in-five residents in their late teens and twenties, precisely the years when STI exposure is most common and least expected, are navigating that reality without much infrastructure nearby.
For the smaller share of households renting at rates near the area median, already a significant monthly commitment on Long Island, sliding-scale or low-cost appointments aren't a minor detail; they're what makes testing realistic rather than theoretical. That cost question sharpens further for any resident whose employment status has shifted: someone currently outside the labor force or between jobs here faces both the drive and a fee structure that can vary considerably between sites listed on this page.

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 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.
