Janet enjoyed playing all types of games and lived a lucky and blessed life, while enjoying time with her children, grandchildren and great grandchildren.

She raised six children and did some secretarial work for the Board of Realtors. She eventually obtained her license to be a professional Realtor and helped many people with their real estate needs. Later, she became the Executive Director for the Board of Realtors in our area. Besides all the normal tasks of this occupation, she was also known as “mother Grimsley” as people often sought her out due to her wisdom of many years in the profession, of being a spouse and a mother.

She wintered in Texas for many winters. She was a devout convert to her Catholic faith. If one word could describe her, it might be SPARKLE as she added light to everyone’s path she crossed.

Survivors include her six children: Mary Hacker and her husband Charles of Sioux City, Jerry Grimsley and his wife Judy of Sioux City, Thomas Grimsley and his wife Gina of Sioux City, Ron Grimsley and his wife Brenda of Sloan, IA, Craig Grimsley of Bronson, IA, Ann Hollis and her husband Gerry of Olathe, KS; 21 grandchildren: Amy Hacker, Jenny Cramer, Britnee Jorgensen, Lindsay Hacker, Treye and Shay Hacker, Jaimee Grimsley, Kellee Hildreth, Lindee Brosamle, Jessica Barnes, Dylan Grimsley, Hannah Grimsley, Josh Grimsley, Holly Smith, Jordan, Alex and Hylarie Dorpinghaus, Kellen and Louden Grimsley, Morgan Ilaria, and Kendal Benson, 36 great grandchildren, and her sister Jo Ellen Baack.
