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.

Dr Kalonaros is a caring, wonderful doctor with an outstanding bedside manner with his patients. He listens carefully and attentively to all my medical concerns. He is never quick to complete his analysis and, never too busy to make me feel comfortable with his medical treatment.
He has always been a doctor I can trust and rely on for my medical needs. He has always shown kindness and compassion for my medical needs.
I feel very lucky to have Dr Vasilios Kalonaros for my doctor- Thank you, MDVIP!!

Dr. Kalonros is fantastic, he takes the time to listen and really get to know you along with the health issues or concerns you have. This is my first concierge physician and I will never go back to a general practice. The benefits that come along with the concierge service and the caring staff at Dr. Kalonaros office is well worth it, even for someone that does not visit the Doctor often.

Dr. Kalonaros is a very attentive physician who truly cares about the well being of his patients. In my personal experience, he was my advocate while hospitalized in a facility he was not affiliated with, and they partnered to get me the best care during my recovery. He is reachable 24/7, probably not to the delight of his lovely wife, but he takes his oath seriously. A straight shooter when giving you information, Dr. Kalonaros is a compassionate and caring physician. It's why I've been with his practice for over 26 years. I highly recommend him to anyone seeking a new practice.

I am a brand new patient from a family referral but he treats everyone like it’s his own family. I had a complex acute medical issue and he was the first professional who looked at the whole picture and broke it down for my husband and I so we could finally move forward in my recovery.

He is very understanding and knowledgeable. He may be the only primary I’ve had who knows about a variety of conditions and is spot on with them (the man knows his stuff about migraines where previously only neurologists could advise me when I was under the care of my old PCPs)

For what it’s worth: I do work in direct patient care and after one visit I can attest: this man is truly an incredible doctor. You’d be lucky to have him, I know I am.

from Arlene in NY • March 10, 2024
I was dealing with ( and still am ) a breathing issue that required me to invest in a nebulizer. I knew i had to get one real soon and Dr Kalonaros
had one in the office and gave it to me. I offered to either pay for it or replace it but he said it wasn't necessary. At that time he was a new doctor for
me and i was so surprised that he did that and so grateful.
