Phoenix, AZ – Maureen Elizabeth McCarthy, known affectionately as “Mo,” passed away on September 10, 2025, at the age of 71 due to a ruptured aneurysm. Her sudden death has left a profound impact on her family, friends, and the community she served during her long career at the Mayo Clinic.
Born on July 22, 1954, in Detroit, Michigan, Mo was the daughter of Charles W. Farrell and Loretta E. Farrell. She was remembered as a cheerful, faithful, and hardworking wife and mother, dedicated to her family and her Catholic faith. Mo met her husband, Thomas K. McCarthy, while he was pursuing graduate studies at the University of Michigan in Ann Arbor. The couple married on August 7, 1982, and went on to have five children together: Brian, Molly, Thomas, John, and Eileen.
Throughout her life, Mo embraced a role that was diverse and dynamic, moving her family across several states, including Arkansas, Texas, Florida, New Hampshire, and Arizona. Known for her meticulous organization, she was unwavering in her commitments and was invariably punctual when it came to her children’s school drop-offs, sports practices, and music lessons. Mo often selected employment based on family benefits, including health insurance and orthodontic discounts, aligning her career choices with her family’s needs.
Mo devoted 16 years of her professional life to the Mayo Clinic in Phoenix, where she worked as an administrative assistant in the Intensive Care Unit. Tragically, she passed away on the same floor where she spent her career, a testament to her dedication and pride in her role at the renowned healthcare facility. After retiring in 2022, she focused on serving her parish and enjoying quality time with her ten grandchildren.
In addition to her immediate family, she is survived by her brothers and sisters: David Farrell, John Farrell, Joan Byrne, Sheila Volweider, Marianne Farrell, Loretta Hill, and Janet Monahan. She was predeceased by her brother Charles Farrell. Mo leaves behind a loving legacy, including ten grandchildren: Stephen, Katherine, James, Daniel McCarthy; Gabriel Carvalho; Lola, Leo McCarthy; Nolan, Levi McCarthy; and Elsie Dawalt.
The community is invited to pay their respects during the visitation at Shadow Mountain Funeral Home in Phoenix, AZ, scheduled for September 18, 2025, at 6:00 p.m. A Funeral Mass will be held at St. Joan of Arc Catholic Church in Phoenix on September 19, 2025, at 10:30 a.m., preceded by a rosary at 10:00 a.m. In honor of Mo’s memory, donations can be made to her cherished parish, St. Joan of Arc.
Mo’s life was marked by unwavering devotion to her family, her work, and her faith. As a guiding figure to all who knew her, she was known for her wisdom and parenting advice, always ready to offer support whether through her professional responsibilities or personal relationships. Her absence will be deeply felt, yet her impact will endure through the lives she touched.
