My Philosophy and Approach to Wellness...

Practicing good medicine includes a partnership between doctor and patient - a partnership based on mutual trust and respect that is earned, not given. As an MDVIP-affiliated primary care physician, I have more time to develop close relationships with my patients, carefully review records and perform comprehensive exams. Being your private doctor, we can work as a team to formulate a wellness plan that will help you achieve your health goals. There are no short cuts to being healthy and no simple formulas or “one-size-fits-all” approaches when it comes to the well-being of my patients. My personalized primary care practice provides care that can help make a happy, healthy future your reality. Similar to conveniences often associated with concierge medicine practices, I also offer same- or next-day appointments that start on time. 

With over 20 years of practicing in the community, I have relationships with many specialists to help you with your unique needs. I may be your internal medicine doctor, but I also have interests in cardiovascular disease, diabetes, hypertension, pulmonary diseases, arthritis and stroke, among others. I see patients from Lower Fairfield County, Westchester, Stamford, Greenwich, New Haven, Norwalk and other surrounding communities. I am affiliated with Greenwich Hospital and make social rounds at Stamford Hospital and Greenwich Hospital. In addition, for those patients who are unable to come to my office, I will make house calls as needed. I am fluent in English and Greek and have staff members who speak Spanish, Swedish, and some German.

Testimonials from patients of Dr. Katsigiannis

from Sondra in CT March 12, 2020 for Antonios Katsigiannis, MD

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… See more

I met Dr. Katsigiannis 20 years ago when I was in the hospital near deaths door. My doctor at the time was retiring and Dr. Katsigiannis took over my old doctor's practice. If it wasn't for Dr. Katsigiannis I wouldn't be alive today after just giving birth to my first daughter he saved my life. He knew there was a problem from the moment he met me and knew what to do get me… See more
