Joan N. Sloat

Joan was raised in Sterling as the oldest of three sisters. A bright and spirited young woman, she was honored as her high school’s Homecoming Queen and shared her love of music by singing in St. Mary’s Catholic Church choir during her high school years.

She married the love of her life, Kenneth Sloat, and together they raised three children: Christine, Douglas, and Margo. Joan and Ken spent many years living in La Grange, Illinois, where Joan dedicated her career to caring for others as a nurse at La Grange Hospital. In addition to her nursing career, she was also a Mary Kay beauty consultant, a role she enjoyed for the relationships she built and the confidence she helped inspire in others. Her compassion, work ethic, and steady presence left a lasting impact on both her patients and colleagues.

Above all else, Joan was deeply devoted to her faith and her family. In her free time, she found joy in painting and gardening, pursuits that reflected both her creativity and her patience.

In later years, Joan and Ken moved to Arizona to be closer to their children and grandchildren. Joan embraced life fully at PebbleCreek, where she was an active and cherished member of the community. She participated in the bocce ball league, enjoyed water aerobics, was part of the wine club, played many lively games of canasta with friends, and also served as a Unit 19 representative. She was an enthusiastic member of the Red Hat Society and looked forward to monthly brunches with her “cul-de-sac gals.” Joan loved attending community theatre and concert productions, treasured time spent traveling with her husband and friends, and especially cherished the tradition of annual trips with her sisters.

Joan is survived by her son Doug (Tina) Sloat; her daughter Margo (Peter) Mahoney; her beloved grandchildren Ryan (Renae) Rude, Megan (Scotch) Domingo, Shea Mahoney, and Kendra Mahoney; her cherished great-grandchildren Kayleigh Rude, Blake-Ryan Domingo, and Ronin-Dean Domingo; and her sister Mary Lou (Les) Johnson. She was preceded in death by her husband, Kenneth Sloat; her daughter, Christine (Mark) Weaver; and her sister, Janet (Bob) Prescott.

Joan will be remembered for her kindness, quiet strength, deep faith, and unwavering love for her family. Her warmth, generosity of spirit, and joyful presence will be dearly missed by all who knew her.

A Funeral Mass celebrating her life and faith will be held on Thursday, February 19, 2026, at 1:00 PM at St. Thomas Aquinas Catholic Church, 13720 W Thomas Road in Avondale, Arizona.

In lieu of flowers, the family kindly requests that donations be made to Hospice of the Valley in Joan’s memory. Donations may be made at hov.org/donate
