Walk-ins are welcome for gonorrhea, chlamydia, syphilis, rapid and conventional HIV, herpes, hepatitis A, B, and C, and TB, with same-visit treatment for bacterial infections.

Northwell Health-GoHealth Urgent Care in Mineola tests for herpes alongside hepatitis A, B, and C, so a single visit can account for viral infections that a stripped-down panel would miss entirely.
For anyone whose primary language isn't English (navigating symptom descriptions, treatment instructions, or follow-up questions) Northwell Health-GoHealth Urgent Care in Mineola has interpretation services on hand. That standing capability means nothing important gets lost when the conversation turns clinical.

MS Family Medicine in Mineola runs STI testing and same-visit treatment for bacterial infections (gonorrhea, chlamydia, syphilis) through a family practice that accepts Medicaid, Medicare, and most insurance, with fees adjusted by income; appointments required; clinical care conducted in Spanish.
At MS Family Medicine, Spanish functions as a working clinical language: meaning history-taking, diagnosis, and treatment counseling happen directly in Spanish without relay. That operational fact shapes how prescriptions get explained, how follow-up instructions land, and how monitoring conversations actually run.
MS Family Medicine holds standing capacity to prescribe and manage both PrEP and PEP, useful for anyone without a regular provider who needs ongoing HIV prevention medication rather than a one-time test. PrEP requires consistent monitoring, and a family practice that handles it directly keeps that continuity intact.
The testing panel at MS Family Medicine covers hepatitis A, B, and C in addition to gonorrhea, chlamydia, syphilis, and HIV: six hepatitis-related data points across three distinct pathogens, each with different transmission routes and clinical implications. Hepatitis A and B vaccines are also available on-site.

Northwell Health in Manhasset brings hospital-system depth to STI care: HIV testing (rapid and conventional), same-visit treatment for bacterial infections, sliding-scale fees, and hepatitis B and C treatment, all by appointment and available in Spanish.
Spanish is a working clinical language at Northwell Health Manhasset: not limited to intake but available through counseling, medication adherence education, and ongoing HIV management. That continuity means nothing gets lost between a test result and the follow-up conversation about what comes next.
Many HIV-focused clinics end their commitment at a positive result, leaving patients to navigate treatment elsewhere. Ryan White funding at Northwell Health Manhasset keeps the same provider relationship intact from initial testing through ongoing HIV/AIDS medical care, with medication adherence support built into that continuum.
Northwell Health Manhasset prescribes both PrEP and PEP directly: a meaningful fact for anyone without a regular primary care provider or paying cash, since Ryan White and sliding-scale fees extend to PrEP for the uninsured, keeping the medication and the prescribing relationship in one place.

Catholic Health Physician Partners in East Hills accepts Medicaid, Medicare, and private insurance, with a separate PrEP program for uninsured patients. Appointments cover gonorrhea, chlamydia, syphilis, herpes, HIV, hepatitis B and C, and TB, with same-visit treatment for bacterial STIs.
Chasing PrEP or PEP across multiple providers means gaps, in coverage, in timing, in follow-through. Catholic Health Physician Partners prescribes both prevention medications directly, so the clinical relationship that started with a test doesn't have to fragment the moment prevention becomes the next step.
Catholic Health Physician Partners carries hepatitis C treatment on-site, direct-acting antivirals managed within the same practice that ran the hepatitis C antibody and confirmatory RNA testing. Keeping treatment in-house means monitoring and dosing adjustments happen without handing the patient off to a separate specialist.
Catholic Health Physician Partners tests for herpes and both hepatitis B and C in addition to gonorrhea, chlamydia, syphilis, and HIV, which means infections that a shorter panel would miss are caught at the same appointment, opening the door to treatment before they progress silently.

STD stats & rates
How reported STI rates in Nassau County, the county that includes Williston Park, 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.
#22 of 62 New York counties for chlamydia, a higher rate than 65% of the state
| Infection | Nassau County | New York | United States |
|---|---|---|---|
| Chlamydia | 328.3 4,536 cases ▼ 41% | 558.4 | 492.2 |
| Gonorrhea | 70.1 968 cases ▼ 70% | 235.6 | 179.5 |
| Syphilis (P&S) | 7.7 107 cases ▼ 48% | 14.8 | 15.8 |
| Syphilis (early) | 10.9 150 cases ▼ 53% | 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 Nassau County, chlamydia has risen from 299 to 328.3 per 100,000 (10%), gonorrhea has risen from 67 to 70.1 per 100,000 (5%), and P&S syphilis has risen from 3.6 to 7.7 per 100,000 (114%).

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 Nassau County.
Local HIV snapshot
Nassau County HIV care continuum (2023)
Nassau County recorded 6.9 new HIV diagnoses per 100,000 (2023), against 14.1 statewide and 13.7 nationally. Among Nassau County residents living with HIV, 78.4% are in care · 74.2% 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 Nassau County tests for syphilis.

Data & references
Local context
Hillside Avenue on a weekday morning moves at its own deliberate pace: the kind of commute rhythm that makes a clinic errand feel like one more thing to fit in, yet most of the listed options here are reachable in under fifteen minutes along NY 25B or Jericho Turnpike without ever touching a highway on-ramp. That accessibility matters more than it might first appear in a place where nearly three in five households are high earners and well over three-quarters of residents own their homes, stability that can make routine health maintenance feel deferrable precisely because nothing feels urgent. The community skews toward established households: large family units, a majority of adults who are married, and strong labor-force participation that fills weekday calendars fast.
For the younger adults here, people in their late teens and twenties who represent a meaningful slice of the population and face the steepest risk of an undetected STI, a clinic that fits between a morning meeting and school pickup is the version that actually gets used. Cost pressure is less the obstacle than schedule density; even with $1,880 typical rents shaping how renters budget, the bigger barrier for most is carved-out time rather than the fee itself. A quiet advantage in a village where parking a few blocks from the Clark Botanic Garden is sometimes faster than driving across town to find a spot closer to the door.

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.
