Mark Francis Keating passed away on February 11, 2026, at the age of 65.

Mark was a proud fifth-generation Texan. His paternal grandfather emigrated from Ireland to New York City just before the Great Depression, seeking opportunity in a new land. On his mother's side, his great-great-grandfather emigrated from Edinburgh to Texas in the late 1800s and became general manager of the historic Spur Ranch near Lubbock—one of the largest ranches in Texas at the time.

Mark grew up in Dallas and the nearby communities of Richardson and Sherman. He graduated from Sherman High School in 1978, and Avila University in 1982. Over the years, he also made homes in Platte City, Missouri; Smithville, Missouri; and Overland Park, Kansas.

In 1989, Mark married and later welcomed two daughters, born in 1993 and 1995, who were among his greatest joys.

Mark's career was in medical sales, including with Johnson & Johnson and St. Jude Medical, among others. His passion for music shaped much of his life. He was a well-known radio announcer in Kansas City, working at Q104, KY102, and 106.5 KCI, where listeners knew him on air as "Mark Miller." His love of music and warm, familiar voice made him a beloved presence to many throughout the region.

Mark is survived by his daughters, Courtney Gonzalez-Garcia (Enrique) and Mary Fletcher (Clint); his brother, Blake Keating (Margaret); and his cherished grandchildren, Carter, Hazel, and Cameron Fletcher.

Extremely loyal and deeply devoted to those he loved, Mark treasured his many friendships and will be missed by countless friends in addition to his family.

Services will be held on Tuesday, February 17, at Good Shepherd Catholic Church in Smithville, Missouri. Visitation will begin at 10:00 a.m., followed by the Funeral Mass at 11:00 a.m. [ LIVE STREAM] Entombment will take place at Resurrection Cemetery, Kansas City North.
