November 4, 1959 ~ January 16, 2020

Sandra L. Onnen, 60, Brandon, SD, died Thursday, January 16, 2020, at Sanford USD Medical School, after a sudden illness.

Visitation with family will be 5-7pm, Monday, January 20, 2020, at the Spirit of Truth Lutheran Church, Brandon, SD.  Memorial Services will be 11:00am, Tuesday, January 21, also at the Spirit of Truth Church.

Sandra Lee Doering was born November 4, 1959 to Kenneth and Edna (Sample) Doering, one of three children, in Madison, where she was raised and attended school. After high school, Sandy attended Dakota State College, where she started as a server at Pizza Hut. She worked her way up to management, and in 1997 advanced to Region Manager, the first female Region Manager for Pizza Hut/NPC International. In 2010, she was offered Director of Training, her most rewarding position. After 7 years in the training role, she returned to operations in the Dakotas region to finalize her career. She retired from Pizza Hut/NPC International after a 40-year career shortly before her death. 

She moved to Brandon in 1990 and married Matt Onnen. They had a blended family, and eventually added Cassie. Cooking and baking were her specialties. She loved to make cheesecake, pasta, egg bake and breakfasts. The kids loved to come over to see what she was cooking, and friends got goodies to take back to college. She loved Sudoku and brain game puzzles, crocheting, made dresses and blankets – even winning awards at the fair.

Sandy will be deeply missed by her husband of twenty eight years, Matt; three children, Kyle (Tiffany) Vanhove, Tea, Alec (Shelbie) Vanhove, Sioux Falls, and Cassie Onnen, Sioux Falls; two grandchildren, Paige and Norah; mother, Edna Doering, Madison; two siblings, Kirk (Carolyn) Doering, Lakefield, MN and Pam Frede, Madison; and many nieces, nephews, and cousins.

She was preceded in death by her father, Kenneth Doering.

    So sorry for you loss. Sandy grew up a mile from my late grandma. She was always there for my grandma whenever she needed her even later in life if she was coming to Sioux Falls (when we lived there) she would bring grandma Ann with her to visit us. Our thoughts and prayers are with Edna, Pam and Kirk and all of Sandys family.

    My heart goes out to the family. Sandy and I became friends back in the early 70’s and shared a love of horses and dancing, having a good time at the old Grand View. Like many of us, she made some bad choices early on in life, but all that turned around when she met the love of her life, Matt. Thank you Matt for making Sandy so happy. Shirley she will be missed my those who love her so much. May God bless you all.
