Mary worked for Doerr Siding for 38 years before retiring in 2012 to take on the role she treasured most—being the best Mimi ever to her precious grandchildren, Hunter and Abby. In retirement, Mary also enjoyed spending her winters in Florida, where she made many wonderful memories with friends. She was never afraid to speak her mind, incredibly generous, and fiercely loyal to her family and those she loved. Mary was loved by many and will always be remembered for her unmistakable laugh, her fun-loving spirit, her style, and her ability to light up a room.
