Rockland Pulmonary and Medical Associates is a combined lung-specialty and primary care practice in Rockland County, New York, with its main office at 2 Crosfield Avenue, Suite 318, in West Nyack and a second office at 257 Lafayette Avenue, Suite 340, in Suffern. Both offices share one appointment line: 845-353-5600. Weekday hours generally run from 8:00 a.m. to 5:00 p.m. (Monday to Thursday) and 8:00 a.m. to 4:00 p.m. on Friday, and the offices are closed on weekends.
The group has cared for Rockland County patients since the late 1970s. Today it is part of Bon Secours Medical Group, a member of the Westchester Medical Center Health Network (WMCHealth). That is why you will often see it listed under longer names such as “Bon Secours Medical Group Pulmonology Rockland Pulmonary Medical Associates.”
What makes the practice a little unusual is that it puts board-certified pulmonologists and internists under one roof. You can see a lung specialist for COPD, asthma or a sleep problem, and keep your primary care with an internist in the same suite. Below you will find the doctors, the services, both office locations, hours, and practical tips for your first visit.

A quick note on names: patients, insurers and online directories use several versions. “Rockland Pulmonary and Medical,” “Rockland Pulmonary & Medical Assoc., PC,” and “Rockland Pulmonary Medical Associates” all refer to the same group. If your referral or insurance card shows one of these, you are in the right place.

Doctors and Providers at Rockland Pulmonary and Medical Associates
The roster below reflects providers listed for the practice in WMCHealth’s directory and major physician directories as of October 2026. Staff change over time, so check with the front desk when you book.
Pulmonologists and Critical Care Physicians
| Physician | Specialties | Notes |
|---|---|---|
| Jonathan I. Berg, MD | Pulmonary disease, critical care, internal medicine | Board certified in pulmonary disease and critical care; sees patients in West Nyack and Suffern |
| Errold Reid, MD | Pulmonary disease, critical care, internal medicine | West Nyack office |
| Stephen M. Menitove, MD | Pulmonary disease | West Nyack and Suffern |

| Jack Horng, MD | Pulmonary disease, critical care, sleep medicine | Also provides primary care |
| Leon Scott Harris, MD | Pulmonary disease, internal medicine | Longtime member of the group; West Nyack and Suffern |
Several of these physicians are also intensivists who care for patients in the ICU at the affiliated hospitals. In practice, that means the doctor you see in the office may be the same one who follows you if a COPD flare or pneumonia puts you in the hospital.
Internal Medicine (Primary Care) Physicians
- Kirithika Mohanathaas, MD – Internal medicine; board certified; joined in 2024 and accepting new patients in West Nyack
- Lisa A. Ferrara, MD – Internal medicine
- Parag Shah, MD – Internal medicine (board certified)
- Dean Miller, MD – Internal medicine; Suffern office
- Diane R. Deschino, MD – Internal medicine
- Sakina Khan, MD – Internal medicine
Cardiology
- Richard Cantor, MD – Cardiovascular disease, nuclear cardiology and echocardiography. Having a cardiologist in the same practice helps when breathlessness could be coming from the heart, the lungs, or both.
Nurse Practitioners
- Eui Kim, FNP
- Rachel Miller, FNP
- Patricia Underwood, Adult Health NP
- Annemarie McDermott, DNP
- Kathleen Begley Pritzker, ACNP
- Michele Muldoon, APRN
Nurse practitioners often handle follow-up visits, medication checks and same-week sick appointments, which can be a faster way in when a physician’s schedule is booked out.
Services Offered
Because the practice blends lung care and primary care, the list of services is broader than at a typical pulmonary office.
Pulmonary (Lung) Care
According to Cleveland Clinic’s overview of what a pulmonologist does, lung specialists diagnose and manage conditions of the airways, air sacs and lung blood vessels. At this practice, that typically includes:
- COPD and emphysema – diagnosis, inhaler plans, flare prevention and oxygen assessment
- Asthma – including difficult-to-control and adult-onset asthma
- Chronic cough and shortness of breath – working out whether the cause is in the lungs, heart or elsewhere
- Abnormal chest X-rays or CT scans – including lung nodule follow-up
- Interstitial lung disease and sarcoidosis
- Bronchiectasis and recurrent chest infections
- Pulmonary hypertension screening – especially when it is linked to lung disease or low oxygen, often called Group 3 pulmonary hypertension
- Follow-up after blood clots in the lungs, such as after treatment for a pulmonary embolism
Breathing Tests
Pulmonary function testing is central to almost every lung workup. As StatPearls explains in its review of pulmonary function tests, these tests do not give a diagnosis on their own, but they measure how well your lungs move air and transfer oxygen, grade severity and track response to treatment.
| Test | What it measures | Typical “normal” marker |
|---|---|---|
| Spirometry | How much air you can blow out, and how fast (FEV1, FVC) | FEV1/FVC ratio above 0.70; FEV1 and FVC above 80% predicted |
| Lung volumes | Total lung capacity (TLC) and trapped air | TLC above 80% predicted (below 80% suggests restriction) |
| Diffusion capacity (DLCO) | How well oxygen crosses from air sacs into blood | Above 75% predicted |
| Bronchodilator response | Whether airflow improves after an inhaler | A clear rise in FEV1 or FVC suggests reversible narrowing, as in asthma |
| Six-minute walk test | Exercise capacity and oxygen levels on walking | Compared with your own past results and predicted values |
If you want the background on why diffusion matters, our guide to gas exchange between the alveoli and pulmonary capillaries walks through it step by step.
Sleep Medicine
Two of the group’s pulmonologists list sleep medicine as a specialty, and the practice has a sleep coordinator on staff to arrange testing. The most common reason for referral is suspected obstructive sleep apnea. Mayo Clinic lists the classic signs: loud snoring, pauses in breathing that a partner notices, gasping at night, morning headaches and heavy daytime sleepiness. Ask whether your study would be done at home or in a sleep lab, since that depends on your symptoms and insurance.
Critical Care and Hospital Care
Many of the pulmonologists are also board-certified intensivists who round at the affiliated hospitals. This continuity is useful for people with advanced COPD, pulmonary fibrosis or frequent pneumonias, where hospital stays can happen.
Primary Care and Internal Medicine
The internists provide adult primary care: annual physicals, screenings, blood pressure, diabetes and cholesterol management, vaccinations, and electrocardiograms (ECGs). Having your primary doctor and lung specialist in one practice makes it easier to share test results and keep medication lists in sync.
Telehealth and Patient Portal
Some providers offer telehealth follow-ups. Test results, refill requests and secure messages run through the WMCHealth patient portal, which many patients find easier than waiting on hold.
What to Expect at Your First Visit
- Book by phone. Call 845-353-5600. Say whether you need pulmonology or primary care, and ask for the office (West Nyack or Suffern) that suits you.
- Check your referral. Many HMO and managed Medicare plans need a referral before a specialist visit. Ask your primary care doctor’s office to send it ahead of time.
- Gather your records. Bring recent chest X-ray or CT reports (or the disc), prior breathing test results, and a full list of medicines, including inhalers.
- Prepare your story. Cleveland Clinic suggests jotting down how long symptoms have lasted, what triggers them, your smoking or vaping history, and any work or home exposures such as dust, chemicals or birds.
- Ask about inhalers before testing. If breathing tests are planned, the office may ask you to hold certain inhalers beforehand. Do not stop any medicine unless the staff tells you to.
- Arrive early. New patient paperwork and insurance checks take time, so plan to arrive 15 to 20 minutes early.
- Leave with a plan. Expect a history and exam, possibly breathing tests that day or later, and a follow-up visit to go over results.
Insurance and Billing
As part of Bon Secours Medical Group and WMCHealth, the practice works with many commercial plans, Medicare and Medicaid managed care plans. Plan networks change every year, though, so call both your insurer and the office to confirm the practice and the specific physician are in network. Billing questions go through WMCHealth’s billing and financial assistance channels.
What Patients Say
Public reviews are mixed. Patients frequently praise individual doctors for being thorough, caring and good at explaining results. The most common complaint is about phone access: with one shared number for many providers, getting through or getting a call back can be slow. A few practical workarounds help:
- Use the patient portal for refills, results and non-urgent questions.
- Call early in the morning, when lines tend to be less busy.
- Ask for a nurse practitioner visit if your physician’s next opening is weeks away.
- For anything urgent, such as chest pain or sudden severe breathlessness, call 911 rather than the office.
When to See a Pulmonologist
Your primary care doctor may refer you to Rockland Pulmonary and Medical Associates, or you may decide to book yourself if your plan allows it. Common reasons include:
- A cough that lasts more than 8 weeks
- Shortness of breath with stairs or everyday activity
- Wheezing or chest tightness that keeps coming back
- An abnormal chest X-ray or CT scan, including a lung nodule
- Loud snoring with daytime sleepiness
- Unexplained low oxygen readings on a pulse oximeter
- Ongoing breathlessness after a blood clot in the lungs
Breathlessness that does not have a clear lung cause sometimes points to the lung’s blood vessels. Our guides on how pulmonary hypertension is diagnosed, how it is measured and its common causes explain why a lung specialist may order an echocardiogram alongside breathing tests. If you are unsure how this differs from ordinary high blood pressure, see hypertension vs. pulmonary hypertension.
Go to the emergency room instead if you have sudden shortness of breath, chest pain that worsens with breathing, coughing up blood, or a swollen painful leg. These can be signs of a pulmonary embolism. Learn how to know if you have a pulmonary embolism and how doctors confirm one.
