Donna L. Sleeth, 78, of York, passed away peacefully on May 8, 2026. She was the beloved wife of many years to James Timothy "Tim" Sleeth.

Born December 27, 1947, in York, Donna was the daughter of the late Ralph E. and Florence Anna (Hilbert) Keener.

Donna was a 1966 graduate of Dallastown High School. She worked for many years in the automotive industry in tire sales and later served as a receptionist for York Building Products, where she enjoyed meeting and helping others.

A faithful and devoted member of St. John's Blymire's U.C.C., Donna was a life member of the church and cherished the friendships and fellowship she found there. She especially loved trips to Ocean City, Maryland, gardening, reading, and, most of all, spending time with her family, whom she loved dearly. She also took great joy in spoiling her beloved granddogs, Gabbie and Darbbie, with plenty of dog cookies.

In addition to her loving husband, Tim, Donna is survived by her daughter, Tracey Dilling and her wife, Kim; her granddaughter, Kiersten Dilling; her sisters, Joyann Yancey and Pam Felger and her husband, Gary; and her nieces, Sue White, Penny Shisler and her husband, Doug, Vickie Garrett and her husband, Harold, Kelly Patterson and her husband, Jeff, Shawna Shaw and her husband, Brad, and Cindy Karch and her husband, Eric.

In addition to her parents, Donna was preceded in death by her son, David Dilling.
