About Antonios Katsigiannis, MD
My internal medicine practice is in Stamford, Connecticut. I have been a primary care doctor for more than 20 years. As a personal physician, I realize it takes more time to really get to the bottom of an answer when asking a patient, “How are you doing?” As an MDVIP-affiliated physician, I have more time to listen and review concerns on a deeper level. My goal is more personalized, integrated care focused on you and your individual health needs.
I have a smaller practice size, which allows, phone calls to be answered by a person and, most importantly, visits that are relaxed and not rushed. My patients can come in for same- or next-day appointments and they can call me after hours for more urgent matters.
My MDVIP-affiliated practice offers services, including comprehensive, advanced health screenings and diagnostic tests, that go far beyond those found in traditional medicine practices. Those services are part of the annual MDVIP Wellness Program. The results can help provide a deeper picture of your health, and with this information, we can develop a customized action plan.
I am affiliated with Greenwich Hospital and make social rounds at Stamford Hospital. In addition, for those patients who are unable to come to my office, I can make house calls as needed. I am also fluent in Greek.
I am excited to have time and more focused energy aimed at helping to pursue improved health and quality of life.

Reviews from the web



Has been an exceptionally smart and effective Doctor and has saved my life twice. I have the highest regard for him and his expertise. Maria and current staff are very kind and helpful always.




While I am not a fan of concierge medical practices because of the expense and “elitist” aspect of it, I made the exception to stay with Dr. K. because he is the best physician I’ve ever had. He was also my mother’s physician for many years before she died at 90 yrs of age.

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.
