Elinor Ann (Callahan) Diamond, affectionately known as “Ellie,” 89, a longtime resident of Chelmsford, Massachusetts, passed away peacefully on November 6, 2026, surrounded by love. She was the daughter of the late T. Bradley Callahan and Alice (Agrodnia) Callahan.
Ellie was a woman with an unmistakable sense of style, a spirited personality, and just the right amount of sass. A true fashionista at heart, she loved shopping, beautiful clothes, and always looking her best.
A graduate of the University of New Hampshire, where she met her future husband, Douglas, Ellie began her career teaching physical education in Rome, New York. She later taught swimming lessons in the family’s backyard pool and worked as a substitute teacher in the Chelmsford Public Schools. She eventually found her professional calling in real estate, enjoying a long and successful career serving families throughout the Merrimack Valley.
Ellie shared many wonderful years with her beloved husband, the late Douglas H. Diamond Sr. Together, they enjoyed annual trips to Aruba and countless days boating and spending time with family on Lake Winnipesaukee, creating memories that would be cherished for generations.
Above all, Ellie’s greatest joy was her family, especially her grandchildren. Being “Mimi” meant the world to her, and the special bond she shared with them was one of the greatest treasures of her life.
In addition to her parents, Ellie was predeceased by her beloved husband, Douglas H. Diamond Sr.; her brothers, Edward Callahan and John Callahan; and her favorite son-in-law, James T. Ravanis.
She is survived by her loving children, Christopher J. Diamond and his longtime partner, Lori Krohner; Kerry Ann (Diamond) Ravanis; and Douglas H. Diamond Jr. and his fiancée, Rosana De Oliveira Lopes. She also leaves behind her cherished grandchildren, Nicholas T. Ravanis and his wife, Kaitlyn, and their son, Julian; Lucas J. Ravanis; and Rachel E. Ravanis and her fiancé, Christian Lucchesi; her sister, Margaret (Callahan) Jarvis, and her husband, William; along with many nieces and nephews.
Ellie will be remembered for her love of family, her independent spirit, and the special sparkle she brought to the lives of those who knew and loved her.
Rest in sweet eternal peace. You were so loved. And heaven, look out — you’re in for quite a ride!
A celebration of Ellie’s life will be held at a future date.
