My Philosophy and Approach to Wellness...

I believe that every patient is unique and deserves individualized care. As a physician, it is my job to build a strong personal relationship with you so we can address your unique and individual needs. With my personal attention to your health, wellness and emotional concerns, we will strive to achieve and maintain your optimal health. I am honored that many of my patients consider me a close member of their family, and I welcome the opportunity to cultivate this type of caring relationship with others. My MDVIP-affiliated practice provides me with resources and tools and most importantly, it allows me the time needed to develop the close bond with my patients that is essential to helping them lead the healthiest lives possible.

from James in NY March 30, 2023 for Vasilios C. Kalonaros, MD

Dr Kalonaros strength starts with his experience and strong listening skills. This allows him to have a meaningful dialogue around any issue and bring a wholistic perspective to the conversation. His caring, commitment and level of engagement make him a valued partner in my health care.

from Mary in NY March 14, 2020 for Vasilios C. Kalonaros, MD

A patient should always be able to say that they have confidence, trust and respect in their physicians medical advice. A few years ago my mother, also a MDVIP member, celebrated her 90th birthday. We had a large party for her, and Dr. Kalonaros was invited. My Mother had a wonderful time and even danced with all the men, including Dr. Kalonaros, who attended. Two days later she had… See more

from Frederick JR in NY March 11, 2020 for Vasilios C. Kalonaros, MD

My family have been patients of DR Kalonaros since the early 80"s. He is very personable and never rushes you out of the office. Our families range in ages of 18 years to 83 years of age, with my Dad being the oldest. Dad was a heavy smoker and has had 2 bouts with lung cancer.

I was having severe palpitations and went for an office visit. Dr. Kalonaros took an EKG. He did not like the results. He immediately referred me to Dr. Balveen Singh a cardiologist.

When I moved to Long Island from Manhattan, I knew I would need to find a new doctor. Personality and a sense of caring was something i wanted in a new doctor. However, Doctor-shopping was not something I looked forward to. After all, how do you interview doctors? What questions do you ask when you want to determine is if you and your new doctor will get along? My friend suggested that i… See more

from Mark in NY February 28, 2020 for Vasilios C. Kalonaros, MD

Being north of 60 years old now, I have had my share of experiences with doctors, even going back to (when I was a child) where they made house calls.

Doctor Kalanorous was referred to me by a neighbor when I first moved to the area in 2001 ish. After changing jobs and insurance and him joining MDVIP, I moved to another practice, and then another. Although these were highly recommended… See more

from Richard in NY March 10, 2018 for Vasilios C. Kalonaros, MD

I have been a member of MDVIP for at least 15 years. It is such a great experience to be able to spend an hour with a doctor discussing your health and
life style. The doctor gets to know you and recommends other specialists to make sure your in good health. eyes, heart, melanoma, ---I highly recommend MDVIP if you can afford.

I was once 410#. I only would see a doctor in an emergency because my experience with the medical community was very degrading. Everything I sought treatment for was somehow caused by my weight. I was disrespected and considered myself to have been a person who suffered from supervised neglect. I met Dr Kalonaros after I had begun my gastric bypass journey. I finally had a physician who… See more
