My Philosophy and Approach to Wellness...

In order to live each day to the fullest, no one can take their health for granted. It is my job to support and encourage my patients in every aspect of their lives. As an MDVIP-affiliated physician, I strive to provide excellence in health care by developing close and personal relationships with my patients in order to easily and effectively diagnose and treat. The following quote summarizes my beliefs as a physician, "Excellence is the result of caring more than others think is wise, risking more than others think is safe, dreaming more than others think is practical and expecting more than others think is possible."

Testimonials from patients of Dr. Fennell

from Regina in CT March 25, 2020 for Gail M. Fennell, MD

I am certain that Dr. Gail Fennell's thoroughness and concern is the reason my lung cancer was caught in its earliest stage, which saved my life! She is always the voice of reason and wisdom, and sometimes even has to display some "tough love" when I wanted to put things off. My annual physicals are so comprehensive that I don't think I have ever know so much about my own body and health. I… See more

from Angela in CT March 12, 2020 for Gail M. Fennell, MD

We have been Dr. Fennell’s patient for twenty years and no matter when we call her, she is always there for us. We have called at midnight from the hospital ER and she has organized the best care providers available, or called just to be reassured about test results.

Gayle was really a partner in saving my life. I have to yell… See more

from Kathleen in CT March 10, 2020 for Gail M. Fennell, MD

Dr. Fennell is amazing. She is very detail oriented and spends so much of her valuable time going over every aspect of your blood work, etc., during your physical. She recommended a gluten free diet for me and it works. Not only have I lost weight, but my numbers improved greatly.

I am so I appreciative of Dr Fennell and the time she spends with me when I have small to large issues with my health. Sometimes I know that I struggle with problems and she never fails to help me understand what is going on and try to help me solve the problem. I also like that she is on Facebook which gives a feeling of being a friend and has fun like the rest of us.
