Rebecca M. (Cook) Brimmer, 80, of Pine City, passed away on August 13, 2026 surrounded by her loving family.

She was born on October 15, 1945 in Elmira, the daughter of the late Arthur P. and Ruth (VanDemark) Cook.

In her spare time, Rebecca loved to work with silk flowers, making arrangements and wreaths. She loved crafting including making things with plastic canvas. Rebecca was an avid reader. Holidays were where memories were made. She loved to decorate her home, inside and out, for Christmas and her Christmas Village was legendary. Rebecca was a vegetable gardener and took excellent care of her hummingbirds. Her strawberry rhubarb pie was a summer staple for dessert. Rebecca spent many summers at Keuka Lake, making memories with her family. Above all, she will be remembered as a loving and devoted wife, mother and grandmother. She made sure everyone was well-fed and loved. She was "Dr. Grandma" to her grandchildren's toys, fixing them with careful precision. She was selfless, always worked on a project and usually gave that project to others. She lived for her family.

In addition to her parents, Rebecca was preceded in death by her son, Scott W. Brimmer on April 3, 2004; her sisters, Bettey Bowen, Mary Compton, and Shirley Cory and her brother, Kenneth Cook.
