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

Testimonials from patients of Dr. Fennell
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. Her calm and caring demeanor ensure no matter what’s going on we will be ok. She is so much more than a doctor. Gail is that… See more

Gayle was really a partner in saving my life. I have to yell… See more
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. When I fractured my knee over a holiday weekend, she spoke with the doctors at the emergency room and then… See more

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.

Dr. Fennell is extremely knowledgeable and very caring.. I am so grateful to have Dr. Fennell for my medical needs.
Dr. Fennell, Thank you for assessing my health and keeping me here on earth far longer than I ever expected. The medication you prescribed and the physical activities you suggested have been most helpful. Can't wait to see the new office. Gratefully, Marie B.
Our family has been under Dr. Fennell's care for years. We know we can count on her immediate care whenever needed.
