Meet Jonathan S. Lown, MD


As an Internist, I have developed a deep understanding of wellness and long-term healthcare. My approach focuses on helping patients live better and longer lives through both acute and preventive care. I give every patient personal advice and support in a relaxed and unrushed manner. I utilize the latest advancements in medicine and knowledge of the latest discoveries in medical research and wellness screenings to help identify risk for disease and prevent it or treat it early. It is also important to me to foster and promote optimism and good humor, which are also important elements in the healing process and staying well. 

I focus on primary care, internal medicine, cardiovascular health, preventive medicine and women’s health. In addition, I am board certified in sleep medicine and am able to treat sleep-related illnesses, such as obstructive sleep apnea and insomnia while providing guidance on CPAP management. By promoting physical and mental well-being and coaching healthier lifestyle choices, I help empower my patients to live the best life possible. I also offer conveniences, like same- or next-day appointments that start on time, which may be found in concierge medicine practices. 

My private primary care practice currently serves all of Long Island, New York. My office is conveniently located in Commack, which is easily accessible from Eastern Nassau County and Western Suffolk County. I am affiliated with St. Catherine of Siena Medical Center in Smithtown, New York. I speak fluent English and Spanish.

Frequently Asked Questions

Doctors who operate in the MDVIP models typically see far fewer patients than traditional primary care doctors. That gives them more time to develop deeper doctor-patient relationships that can lead to better outcomes. They can also offer conveniences that most primary care doctors can’t, including same- and next-day appointments. They’re available after hours for urgent matters. And they have time to focus on prevention. That focus begins with the MDVIP Wellness Program, which patients pay for with their annual membership fee.

Most MDVIP-affiliated primary care practices accept insurance (your physician can tell you whether they accept your specific insurance plan). Your annual fee pays for preventive care medical services that insurance usually doesn’t cover (e.g., advanced diagnostic testing and screenings). Your MDVIP-affiliated physician will continue to bill your insurance and charge copays, co-insurances and deductibles as he or she currently does for other medical services like sick visits.

MDVIP makes wellness and prevention easier by providing your physician with innovative tools and technology. MDVIP supports your physician’s practice and seeks to eliminate barriers to a positive healthcare experience. Your doctor will determine whether and how to incorporate these tools at his/her discretion.
