Theresa Ellen Kroeger, 84, passed away on October 6, 2026, in Oklahoma City, Oklahoma. She was born on March 20, 1942, in Guthrie, Oklahoma, to Ray C. and Dorene (Casey) Deadwiley.

Caring for others was an important part of Theresa's life. Through her many years as a psychiatric registered nurse, she devoted herself to helping people through some of their most difficult moments. That same spirit of care extended to her family, where her love was expressed through the time and attention she gave to those closest to her.

Theresa was a member of St. Mary's Catholic Church. Above all, she treasured spending time with her family, especially her great-grandchildren, who brought her so much happiness. Those everyday moments together were precious to her, and the love she shared with her family will remain a cherished part of their lives.

Theresa leaves behind her children, Robyn Branch and husband Lester, and Bill Kroeger and wife Whitney; her brothers, Nick Deadwiley and partner Janice, and Pat Deadwiley and wife Cathy; five grandchildren, Brittani Coggins and husband Richard, Haleigh Blackwell and husband Shaun, Ryan Kroeger, Kara Kroeger, and Jay Kroeger; and four great-grandchildren, Maddisen, Mallory, and Grayson Blackwell, and Liam Coggins.

She also leaves behind her dear friend of more than 60 years, Carolyn Nelson. Their lifelong friendship was a special part of Theresa's life and one she treasured deeply.

She was preceded in death by her parents; her son, Shane Kroeger; and her sister, Dee Dee Bolis.

Mass of Christian Burial will be held at St. Mary's Catholic Church in Guthrie, Oklahoma, on Friday, October 9, 2026, at 10:00 a.m., with Rev. Fr. James Wickersham officiating. Burial will follow at Memory Gardens Memorial Park Cemetery in Guthrie.
