Dr. Katsigiannis

Meet 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.

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. K.
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.

I’ve been a patient of Dr. K’s for many years, and think highly of his knowledge and expertise. He keeps on top of current medical research which is apparent to me since I’ve been his patient for many years. He also has an extraordinary dr./patient relationship and personality.

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.

Dr. K is caring, compassionate and wants the best for his patients. He's younger but reminds me of the doctor in a Norman Rockwell picture. He will do a home visit if necessary. I love the fact that during business hours either Maria or Imani will actually answer the phone! They are helpful and help get you into the office I'd needed. Dr. K and the girls are the true meaning of health care!

For Dr. Antonio Katsigiannis

from Mary Ann in CT • March 18, 2024
I am so glad to have this fabulous doctor in my life. I was taken to the hospital in November by ambulance with severe chest pains.

He is so careful, thoughtful, professional in caring for his patients.

My wonderful husband was dying. The care he received, from Dr. Katsigianis, as well as myself and my children, was outstanding. Dr. Katsigianis is not only a superb diagnostician, but a fine human being. So caring, so calm, so understanding. He will have me as a patient forever!

THE BEST DOCTOR!!

from Teaetta in CT • February 22, 2024
My husband had double lung transplant and kidney transplant on August 27, 2023. I do not know how we would have made it without Dr. Katsigiannis. After leaving NYU Langone we needed that support person to report back to NYU Staff and do daily/weekly follow ups as needed. After being transferred to the fist rehab facility my husband took sick. With the help of Dr. Katsigiannis he was taken to Read more...

from Marjolijn in CT • February 13, 2024
We have been patients of Dr. Antonios Katsigiannis for more than 25 years, so there are too many stories to tell.
Suffice it to say that we would NEVER dream of changing physicians as long as he has his practice!
