Josephine “Jo” Mahon passed away peacefully on March 4, 2026. Born on April 12, 1936, in the Bulls Head section of Scranton, she was the daughter of Mary Russo Costanzo and Joseph Costanzo. Jo treasured her Italian heritage and often spoke of her childhood surrounded by her large, close‑knit family.

After marrying the love of her life, Paul Mahon, the couple later settled in Clarks Green, where they built a warm home and lasting friendships. Married for 57 years, Jo cared for Paul with extraordinary devotion during his long illness. When he could no longer work, she dedicated herself to the Scranton School District, where she spent 38 years supporting special‑needs students and forming lifelong bonds with colleagues.

Jo was admired for her beauty, grace, and impeccable style. She loved decorating her home—especially for Christmas—and hosting family and friends. Shopping trips with loved ones were among her favorite pastimes.

Her greatest joy was her family. A loving mother and “Mom Mom,” Jo poured her heart into her children, grandchildren, and great‑grandchildren. Her grandsons were the center of her world, and she delighted in watching them grow into husbands and fathers. Her six great‑grandchildren brought her immeasurable happiness, and she proudly surrounded herself with their photos.

Jo is survived by her daughter, Mary Ellen Conaboy, and her husband, Attorney Bill Conaboy; her son Michael and his husband, Brad White; her sister‑in‑law, Palma Yanni; her three grandsons and their wives; and her six great‑grandchildren. She was predeceased by her husband Paul, her son Paul Jr., and her siblings Pat Yanni, Carmella Emanuel, and Sister Rose Shoener.

The family extends sincere thanks to the caregivers and staff at Allied Terrace, Dr. Richard Weinberger, Allied Services, and the Sinclair Nursing Agency for their compassionate care.

A celebration of life will be private at a later date.
