Thomas Joseph De Marco, 82, of Chesterland, Ohio, and Naples, Florida, passed away on February 6, 2025. A devoted husband, father, stepfather, grandfather, and brother, he is lovingly survived by his wife, Bonna, with whom he shared 40 wonderful years, and his children: Todd (Heather) De Marco, Kristin (Derek Mansfield) De Marco, Lisa (Sam) Tyree, and Bonna’s daughters, Joelle (Pete) Snavely and Dana Kelly. Tom is also survived by his youngest brother, Ray, and his beloved grandchildren: Max, Mia, Rex, Merin, Sylvia, Jack, Jess, Paige, and Ruby.
Tom attended the University of Pittsburgh before launching a distinguished career in dentistry. In 1976, he became the youngest dental school dean in the nation at Case Western Reserve School of Dental Medicine. A dedicated educator and mentor, he shaped the careers of generations of students. Tom practiced periodontics for 56 years until retiring at age 80.
Tom and Bonna split their time between Ohio and Florida, traveling the world, enjoying great food, and making lifelong friends. He found his greatest joy in gathering with family, sharing good wine, lively conversation, and laughter. A natural storyteller, he delighted in collecting and sharing jokes, bringing good humor to all who knew him.
Tom’s legacy is one of generosity, dedication, and a zest for life. He taught us to find humor in life and never miss a good meal with loved ones. Though he is deeply missed, his spirit lives on in the hearts of those he touched.
A private celebration of life will be held in the spring. In lieu of flowers, the family asks that donations be made to a charity of your choice.

Dear Bonna and Family. I had the pleasure of meeting Tom on the pickleball courts. We had some great times on the Court and interesting conversations after our games. I have a copy of his joke book and can picture his laughter. I know he lived a full and active life. He will be dearly missed by all that had the pleasure of meeting him. Larry and Rose Bernstein

Dear Bonna and all that loved him
I am shocked and sad. Although we have not seen each other for a while I have always credited him for my success. Without his support and urging my life would have been much different. Our travels together opened us to new adventures. It would not have happened without both of you. Coffee with him at McDonalds were often fun and informative
If I can do anything to ease the pain please let me know

Dear Todd, Kristin, and Lisa. Aunt Leslie, Christopher and I are sorry that you lost your Dad. I have some pleasant memories of Tom, including a nice visit with him when he was in DC making a presentation to a group of Dentists. I remember Tom coming over to the EEOC Headquarters, walking around the tidal basin with the cherry blossoms in full bloom and going to dinner. Aunt Leslie was at graduate school in Pittsburgh at the time. Over time Tom gave me some good stock tips and when I required some dental surgery, Tom did it for me as a favor. Aunt Leslie, Chris and I offer our profound condolences. Love, Uncle Eddie
