Damian Family Care Centers in Ronkonkoma runs STI care through a family practice model, pairing the standard panel (HIV, syphilis, gonorrhea, chlamydia) with sliding-scale fees and same-visit bacterial treatment; appointments are required, and PrEP and PEP are available for prevention.
Gonorrhea, chlamydia, syphilis, and HIV are what most clinics stop at: Damian Family Care Centers adds hepatitis A, B, and C to the same visit, catching infections that a narrower panel would simply miss until symptoms forced the issue.
A positive hepatitis C result that sends you elsewhere means a second intake, a second wait, and real time lost before treatment starts. A gap that allows liver damage to continue unchecked. Damian Family Care Centers treats hepatitis C on-site, so the path from diagnosis to managed care doesn't stall between providers.
Damian Family Care Centers prescribes both PrEP and PEP directly, which means ongoing HIV prevention is woven into the same relationship as testing: no separate clinic, no gap between where you're seen and where you're protected.

Stony Brook Medicine in Smithtown brings academic medical infrastructure to STI care: the standard panel, sliding-scale fees accepted through Medicaid, Medicare, and insurance, with appointments required and same-visit treatment available for bacterial infections like gonorrhea and chlamydia. Prevention extends to PrEP and PEP.
When prevention requires a prescription, PrEP for ongoing protection or PEP after exposure, a second appointment at a separate facility means a gap in coverage that costs time and, often, adherence. Stony Brook Medicine in Smithtown prescribes and manages both directly, keeping the clinical relationship continuous.
The panel at Stony Brook Medicine in Smithtown runs to six: gonorrhea, chlamydia, syphilis, HIV, herpes, hepatitis B, and hepatitis C. Infections with distinct transmission routes and distinct clinical consequences. Hepatitis C, in particular, carries treatment implications that a narrower panel would leave undetected.

Stony Brook Adolescent Medicine in Smithtown runs by appointment, so booking ahead is the move, and a single visit covers gonorrhea, chlamydia, syphilis, HIV, herpes, and hepatitis A, B, and C on a sliding-scale fee, with same-visit treatment for bacterial infections and hepatitis vaccines on-site.
Stony Brook Adolescent Medicine prescribes and manages both PrEP and PEP in-house, and carries a dedicated pathway for uninsured patients seeking PrEP. Meaning someone without a regular provider or without coverage has a direct clinical relationship here, not a forwarding address.
Hepatitis C treatment is delivered on-site at Stony Brook Adolescent Medicine in Smithtown, not handled elsewhere after a positive result, which means a patient's care relationship stays intact through the full treatment course rather than fragmenting across providers.
The testing panel at Stony Brook Adolescent Medicine extends to herpes simplex and all three hepatitis types (A, B, and C) alongside the standard four, bringing the count to seven distinct pathogens; that breadth means a single appointment can resolve diagnostic questions that a narrower panel would leave open.

STD stats & rates
How reported STI rates in Suffolk County, the county that includes Islandia, compare with New York and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~30% 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 |
| Syphilis (late/unknown) | 10.4 159 cases ▼ 59% | 25.2 | 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 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
The neighborhoods around Lakeland County Park reflect Islandia's character: families who have planted themselves here for decades, houses filled with multiple generations, routines that revolve around work and school and the steady rhythm of staying put. That stability also means people know the value of privacy when health questions arise. Young adults in Hauppauge and Smithtown, those in their late teens through their thirties, often face the practical gap between wanting a screening and finding time to arrange one without drawing attention in a place where faces repeat. STI testing in and around Islandia strips away the complications.
The clinics and providers listed on this page operate with the understanding that confidentiality isn't theater; it's baseline. A person can walk in, get tested, receive results, and leave without their employer, their household, or their social circle knowing anything happened. That boundary matters differently in a community where people stay, where reputation and daily life intertwine. Screening for chlamydia, gonorrhea, HIV, syphilis, and other infections is available through urgent care facilities, primary care offices, and dedicated sexual health clinics within reach.
Many offer same-day or rapid results. Whether someone is between jobs, managing a packed schedule, or simply wants to know their status quietly, the testing infrastructure here accommodates that need without requiring elaborate explanation.
Getting there
At 9.1/20 on the EPA walkability index, day-to-day errands in Islandia 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 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.
