(From Peterson Funeral Chapel)Wanda Mae Tettenhorst was a woman defined by her devotion to her family, her community, and her Lord. Her faith was the cornerstone of her life; she found great joy in interceding for others, motivated always by her love for her Savior, Jesus Christ. On April 15, 2026, she entered her final rest while in home hospice care in Buffalo, Missouri, at the loving home of Rick and Julie Tettenhorst.
Born on December 22, 1946, in Mt. Vernon, Missouri, to Leon and Esther Wormington, Wanda was a proud seventh-generation resident of Lawrence County, descending from one of the twelve pioneering families who settled Southwest Missouri in the 1830s.
A 1964 graduate of Mt. Vernon High School, she always looked forward to reconnecting with friends at her class reunions. After attending Draughon’s Business College, she began a long and dedicated career in clerical and business administration. Her professional journey included roles at MWM Color Press in Aurora, various Lawrence County government offices, and the State of Missouri Circuit Clerk’s office.
Wanda was perhaps best known for her tireless advocacy for US Veterans. Through her work with the Disabled American Veterans (DAV), she helped veterans document their service for VA benefits and coordinated essential hospital transportation.
Wanda was preceded in death by her parents, Leon and Esther, whom she lovingly cared for in her home until her mother’s passing, and by her high school sweetheart and husband, John Paul Tettenhorst, who passed away on January 1, 1985.
She is survived by her two sons and their spouses: Mike (Renee) Tettenhorst of Mt. Vernon and Rick (Julie) Tettenhorst of Buffalo; her grandchildren, Jackson (Hailey) Tettenhorst and Blair (Jason) Obermann; and a growing legacy of great-grandchildren, her brothers Garold (Rebekah) Wormington, Lee (Gaylene) Wormington, and Gary (Teresa) Wormington, and a host of loved nieces, nephews, and cousins. She is also survived by her very dear friend of nearly 40 years, Bill Ballard and his children and grandchildren.
