Shirley A. Trost

Shirley A. Trost, 93, of Waterloo, passed away peacefully surrounded by her family on Saturday, December 27, 2025 at her home. She was born November 24, 1932 in East St. Louis, IL to Herman and Ella (Sparwasser) Klohr. She married LeRoy Trost on April 11, 1953 and they had 72 wonderful years together.

Shirley is survived by her husband Lee; children Dr. Lori Trost (Ed) Siemers, Dr. John (Kim) Trost, Amy (Matthew) McClure, and Mark (Traci) Trost; grandchildren Daniel and Caroline Siemers, Clayton and Alex (Jessica) Trost, Jack and Samuel McClure, Madelyn (Max) Heise, and Isabella Trost; and step grandchildren Alia (Andy) Wildman, Jacob (Kaylee) Adams, Courtney, Casey, and Nate Matheu; and great grandson Harrison Heise. She was preceded in death by her parents and infant sister.

Shirley was a homemaker and mother. She had a love for music, especially the piano and was inducted into the Valmeyer Music Hall of Fame. She loved “the arts”, toll painting, and gardening. Her beautifully landscaped yard, filled with perennials was named “Yard of the Month”. She loved to travel, especially in the family Winnebago all over the United States. But most of all, she loved to play games with her grandchildren - countless hours of dominos, cards, and puzzles.

She was a member of the Sparta United Methodist Church where she played the piano for years, accompanying the congregation and the SonBeams.

Her greatest joy was being with her family and she will be forever loved and missed by those who knew her.

As an expression of sympathy, the family prefers memorial contributions to:Concord Presbyterian Food Pantry

A gathering will be held Saturday, January 17, 2026 at Quernheim Funeral Home from 10am-noon followed by a celebration of life service at noon. Immediately following the service will be a luncheon reception at the Waterloo Country Club.
