Mary Catherine Ulmer, 91, of Sedalia, MO, passed away on Thursday, April 30, 2026, at E.W. Thompson Health and Rehabilitation Center in Sedalia. She was born on May 31, 1934, in Spring Fork, MO, the daughter of John and Margaret (Perkins) Brosch, who preceded her in death.

On July 7, 1956, in Sedalia, MO, she was united in marriage to Stanley E. Ulmer, who preceded her in death on December 2, 2018.

Mary attended and graduated from Liberty School near Spring Fork, MO. She worked for Town and Country Shoes in the heel department. Mary was also instrumental in helping her husband with Stanley Ulmer Auction Services, where she operated the concession stand. Many looked forward to the Tuesday night consignment auctions at the Missouri State Fairgrounds, not only for the auction but also for the wonderful food Mary prepared and served at the concession stand. She continued helping her sons, Steve and Kevin, with auctions until the early 2000s.

Mary enjoyed going to garage sales, crocheting, cooking, baking, and adding to her collection of Roseville Pottery. Above all, she especially loved spending time with her grandchildren and great-grandchildren.

Mary is survived by two sons, Steve Ulmer and his wife, Jan, and Kevin Ulmer and his wife, Kami, all of Sedalia; one grandson, Justin Ulmer and his wife, Beth; two great-grandchildren, Madyson and Rhett; and many nieces, nephews, cousins, and extended family members.

In addition to her parents and husband, Mary was preceded in death by two daughters; two sisters, Edna Klein and Ruth Horrell; and three brothers, Robert Brosch, LeRoy Brosch, and Charles Brosch.

The family will receive friends from 1:00 p.m. until 2:00 p.m. on Thursday, May 7, 2026, at Rea Funeral Chapel. A graveside service and burial will follow at 2:30 p.m. at Calvary Cemetery in Sedalia.
