What Members Are Saying

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. It finally in the hospital for five days diagnosed with gallbladder problems. That doctor called my husband and daughter three to four times a day. He is so careful, thoughtful, professional in caring for his patients.

Patient of Antonios Katsigiannis, MD

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!

Sheila

Patient of Antonios Katsigiannis, MD

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 Greenwich Hospital and was admitted this would have been a total disaster without him. Because my husband was a transplant patient he needed a private room he took care of that as well and my husband takes over 38 medications per day. From there my husband was transferred to a new rehab facility in Norwalk and Dr. Katsigiannis continued to follow him and make sure all medications, schedules all transportation to and from NYU, testing, weekly bloodwork etc., Another thing he would always call me with any changes or updates as they arises. I think of Dr. Katsigiannis not as our doctor but he’s part of our family.

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.Katsigiannis

from Marguerite in CT • January 25, 2024

I have been with Dr. K. for msny years, that I gofget how many. I have always found him to be kind, helpful in many ways. He has been more than a Dr. many times, sometimes a friend, advisor and helpful when needed. He once drove me directly to Greenwich Hospital instead of waiting for an ambulance during which time, Maria, in his office was arranging everything. They took me the instant he Read more...

Solved my problem and saved me $$$$

from Sondra in CT • March 12, 2020

After cataract surgery, it was discovered I had very dry eyes. All the post surgery drops were really irritating. And my eyes weren’t healing. My eye doctor prescribed another drop, one that was specifically for generating tears. It would take weeks and might not work. And as I was on Medicare, not eligible for coupons, it cost me $600 per month. I was distraught, in pain and trapped in a bad Read more...

from Sharon in CT • March 10, 2020

Thursday, New Years Day, my husband landed in the ER where he was diagnosed with cancer.

By the time we saw him on Friday morning, he had assembled a phenomenally qualified team of doctors at Greenwhich hospital/Yale New Haven. They got to work immediately to determine an apppropriate Read more...
