Long Island’s Award-Winning Multi-Specialty Medical Group

Personalized care across primary care, cardiology, and more — now accepting new patients.

Here At Heart and Health Medical, We Put Our Heart Into Your Health

Award-Winning Medical Group

Heart and Health Medical has been serving Nassau and Suffolk County since 2005.

Our board-certified physicians and specialists cover thirteen clinical disciplines – including Cardiology, Allergy & Immunology, Endocrinology, Internal Medicine, Physical Therapy, and Podiatry – operating across five Long Island offices. The group has received formal recognition from the Town of Babylon, the Town of Oyster Bay, and New York State and county legislators for sustained excellence in community healthcare.

Medical Care As Unique As Our Patients

Heart and Health is the only independent, physician-owned multi-specialty group in Long Island, which means that your care is guided by the doctors, not by a hospital system or a corporate organization. The providers are board certified in their respective specialties and communicate directly across departments, thus a patient with a cardiac issue and diabetes, say, will not need to refer to a cardiologist and endocrinologist at separate locations, causing unnecessary delays.

Appointments are available for both new and established patients, with same-day slots offered through our EXPRESS Care service. Most major insurance plans are accepted, including Medicare and Medicaid.

Early Detection & Prevention Specialists

Preventive care is a core focus across all Heart and Health specialties. Our onsite diagnostic capabilities include EKG, echocardiography, vascular ultrasound, nuclear cardiology imaging, pulmonary function testing, allergy skin testing, and on-site blood draw – reducing the need to visit separate facilities for routine workups. Annual physicals consist of blood pressure assessment, full blood panel, body oxygen saturation, and vaccination services.

Among our practices, hypertension, coronary artery disease, asthma, allergic rhinitis, diabetes and thyroid disorders, peripheral vascular disease, chronic wounds, and musculoskeletal injury are common conditions that are managed. Our vascular laboratory is accredited for non-invasive vascular testing. Our cardiology team includes physicians board-certified in both Cardiovascular Diseases and Nuclear Cardiology.

High Quality Care Made Affordable

As a private, physician-owned practice, Heart and Health is not affiliated with a hospital network – which means shorter wait times, consistent provider relationships, and decisions made at the practice level.

We accept most commercial insurance plans, Medicare, and Medicaid, and our billing team can confirm coverage before your appointment.

Our five offices – in Massapequa, Coram, Plainview, North Babylon, and Levittown are distributed across Nassau and Suffolk County, with extended-hour availability at select locations. For patients unable to travel, our Mobile Medical Unit serves communities throughout Long Island directly.

Long Island's Best Doctors

Our Doctors Proudly Serve Long Island

Heart and Health has grown from a single location into a five-office, multi-specialty group over two decades of practice on Long Island. Our team includes board-certified cardiologists, allergists, internists, family medicine doctors, an endocrinologist, a vascular surgeon and physical therapists – supported by certified nurse practitioners and physician assistants across all sites.

Patients have access to both in-person appointments and telemedicine visits through our patient portal and mobile app, with the ability to request prescription refills and view test results online. Our EXPRESS Care service is designed for patients who need timely access without an ER visit – handling acute, non-emergency concerns across our network.
