Antonios Katsigiannis, MD

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, compared to a concierge medical practice, provides the level of care that can help make a happy, healthy future your reality.

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.
