Key points

  • Dr. Shershow evaluates and treats adults 18 and older with ADHD and holds New York and New Jersey licenses; follow-up visits are held by secure video.
  • A video visit taken on Staten Island is a visit in New York: as of October 2026 New York follows federal DEA telemedicine rules, which run through December 31, 2026.
  • New York pharmacies cannot refill Schedule II stimulants; the usual limit is 30 days, with up to three months allowed for attention deficit disorder.
  • Richmond University Medical Center's CPEP at 355 Bard Avenue is listed by the state as open 24/7 for psychiatric emergencies on Staten Island.
  • The Staten Island Ferry is free and takes about 25 minutes each way between St. George and Whitehall.

Staten Island is one of the five boroughs, so adults who live or work there are covered by New York State rules and by a few New York City laws that stop at the city line. It also has its own hospitals, colleges and public services, and a commute that often runs by water. This page covers what is specific to the Island: which rules apply to a video visit taken there, how to fill an ADHD prescription locally, and the public resources on Staten Island that are separate from Dr. Shershow's practice.

Who on Staten Island looks for adult ADHD care

Three groups on the Island tend to have specific practical questions about adult ADHD care.

  • College students. The College of Staten Island (part of CUNY) and Wagner College both have disability offices that arrange academic accommodations (details below). Students often need a current evaluation to use them.
  • Ferry commuters. The Staten Island Ferry is free and takes about 25 minutes each way between St. George and Whitehall in Lower Manhattan. For a commuter, a long day can leave little room for appointments, which is one reason people ask about video follow-up.
  • People who work off the Island. Some Staten Islanders work in Manhattan or Brooklyn, others in New Jersey. Where you sit during a video visit matters, as the next section explains.

None of these is a reason by itself to suspect ADHD. If trouble with focus, organization or restlessness has been present since childhood and is causing problems now, that is worth discussing with a clinician. The adult ADHD self-test is a starting point, not a diagnosis.

Which rules apply to a video visit from Staten Island

A clinician must be licensed in the state where the patient is physically located during the visit. New York State Education Department guidance says a practitioner must hold a New York license when providing services to a patient located in New York. Dr. Shershow is licensed in New York and New Jersey, and for any video visit you must be physically in one of those two states.

Where you are during the visitRules that apply
At home on Staten Island, or at work in Manhattan or BrooklynNew York's. As of October 2026, New York sets no in-person requirement of its own for telehealth stimulant prescribing and follows federal DEA rules, whose telemedicine flexibilities run through December 31, 2026.
At work in New JerseyNew Jersey's. Under P.L.2026, c.40, an adult on a Schedule II stimulant who starts by telehealth needs an in-person visit within 30 days, a contact every three months, and an in-person visit at least once a year.
On a trip to another stateA video visit cannot take place. Reschedule, or plan the visit for a day you are in New York or New Jersey.

If you split time between Staten Island and a job in New Jersey, decide where you will be for visits and tell the office. The office will explain how visits are arranged for patients located in New Jersey. The cross-border details are in living in New Jersey, getting ADHD care in New York (or the reverse).

Filling an ADHD prescription on Staten Island

Pharmacies on the Island follow New York's controlled-substance rules, the same as anywhere else in the state.

  • A Schedule II prescription, which covers most stimulants, cannot be refilled. Each fill needs a new prescription.
  • The usual limit is a 30-day supply. New York allows one prescription for up to a three-month supply when it is written for attention deficit disorder and marked with the condition or its code. Whether a longer supply fits is a decision for the prescriber.
  • Electronic prescriptions go to one pharmacy. Before a new prescription is sent, call the pharmacy you plan to use and ask whether it has the medication and strength in stock.

If a pharmacy is out of stock, practical steps are in the ADHD medication shortage in New York, and the full rules are in New York's rules for ADHD stimulant prescriptions.

Staten Island resources that are not the practice

These services are run by hospitals, colleges, the state and nonprofits. None of them is connected to Dr. Shershow's practice, and crisis and peer services do not evaluate for ADHD or prescribe.

CHADD, the national ADHD nonprofit, lists no chapter in New York City as of October 2026. The nearest chapters, in Nassau, Suffolk and Westchester-Putnam, hold many meetings on Zoom. Whether Staten Island University Hospital offers an adult ADHD service could not be confirmed; ask its psychiatry department directly. Other local options are in adult ADHD care in New York City.

Work and insurance questions for Staten Islanders

Two city laws matter if you work in the five boroughs. The NYC Human Rights Law applies to employers with four or more people and requires a good-faith cooperative dialogue when someone asks for a workplace accommodation. The city's Earned Safe and Sick Time Act gives most employees 40 or 56 hours of paid protected time off a year, which can be used for medical appointments. Your human resources office can confirm how either law applies to your job.

For insurance, New York's behavioral health protections apply to policies issued in New York, not to self-funded employer plans or policies issued in another state. Plans regulated by New York must be able to offer a first outpatient behavioral health appointment within 10 business days, through a complaint process if needed. The office can tell you the current fees and how insurance works with the practice. For background, see does insurance cover adult ADHD care in New York?

  3. Collect what you have: old report cards, any earlier evaluation, a list of current medications, and records from past prescribers. If you have no childhood records, the evaluation can still go ahead; see ADHD evaluation without childhood records.

What to expect at the first visit is on the new patients page.

Questions

Can I get an adult ADHD evaluation from Staten Island by video?

Video care is possible when you are physically in New York or New Jersey during the visit, and a visit from home on Staten Island is a visit in New York. Whether the first visit is in person or by video is something to ask the office when you call. Follow-up visits with Dr. Shershow are held by secure video.

Is there an office on Staten Island?

This page is for Staten Island residents and does not describe an office on the Island. Call the office to ask how visits are arranged.

Do I need a referral to see an ADHD psychiatrist?

Many people book directly. Some insurance plans require a referral or prior approval for specialist visits, so check with your plan. The office can tell you how insurance works with the practice.

Is ADHD testing the same as a psychiatric evaluation?

Not quite. A psychiatric evaluation is a clinical assessment based on a detailed history, symptoms across your life and other possible explanations, and it is the standard route to an adult diagnosis. Neuropsychological testing is a separate battery done by psychologists, which Dr. Shershow does not provide. See the guide's comparison of the two.

I work in New Jersey. Can I take my video visit from my office there?

Dr. Shershow is licensed in New Jersey as well, but a visit taken from New Jersey falls under New Jersey law, including its in-person visit rules for adults starting a stimulant by telehealth. Tell the office where you will be, and it will explain how visits are arranged.

What should I do in a mental health crisis on Staten Island?

Call or text 988, or call 911 in an emergency. Richmond University Medical Center's psychiatric emergency program at 355 Bard Avenue is listed by the state as open 24/7 for walk-in care.
