About John P. O'Connor, MD
I have been an internal medicine physician on the east end of Suffolk County, Long Island, for more than 15 years. My wonderful staff and I strive to provide more personalized and friendly care, with a touch of humor and even background music. My philosophy is founded on empathy, compassion and communication, along with implementing wellness resources provided with MDVIP.
As a primary care physician, I find that the more personalized doctor-patient relationship offered in my practice combined with results of the services included in the annual MDVIP Wellness Program can help in focusing on improving your health span (a concept referring to the number of healthier, disease-free years of life you could experience). My MDVIP-affiliated practice offers services, including comprehensive, advanced health screenings and diagnostic tests, that go far beyond those found in concierge medicine practices. And we offer conveniences, like same-day and next-day visit with minimal waiting, the ability to reach me after hours for more urgent needs and 30-minute routine or sick visits, as needed. Another benefit is care for members’ dependents ages 18-26 (minus the annual Wellness Program).
In my practice, I can also provide you with more individualized care and time together with a greater focus on prevention, as well as more in-depth discussions about your acute and chronic health concerns. As your personal doctor, I can practice medicine the way I have always aspired and work with you to develop an action plan to help you enjoy a healthier, more active lifestyle.
My practice is in Calverton, New York, and serves patients from many areas, such as Riverhead, Miller Place, Rocky Point, Sound Beach and neighboring towns throughout Long Island. Some of our areas of focus are diabetes, hypertension, elevated cholesterol, cardiovascular disease and vascular disease, in addition to prevention and primary care.
I am excited to have more time and focused energy aimed at helping you pursue improvement to your health and your life.

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.
