Dr. Carol McGonigle D.D.S

I am writing this as we begin the brand-new year of 2021. It is certainly a good time to reflect on the blessings and plain-old good luck to have spent over 40 years practicing dentistry in Tucson. Moving here after graduating from the University of Washington in 1980, I never expected to be in a community or a profession that would provide me with so much fulfillment. I am so lucky to have the opportunity now to work two days a week in the practice I love with the people, both team members and patients, that I love. As the wrinkles peek out from under my mask, I am frequently asked when I am going to retire. My answer is “Never.” I enjoy what I do and I am able to do it. Why would I stop?


Along the way, I have raised two children and spoiled two grandchildren. I have divided almost 40 years of marriage between two husbands (looks like this one is going to stick.) I have learned that I need to be embraced each day by the unconditional love of two dogs. My husband and I have a beautiful RV that allows us to escape the Tucson heat with the aforementioned dogs.


This is not so much a biography (an accounting of the past years) but a summation of where I have come to in that time. It is a good place to be.
