Dianne was preceded in death by her parents Angus Helgeson and Florence Helgeson (Hollister) and siblings Jean Watts (Helgeson) and Dick Helgeson. Dianne is survived by her loving husband, Jack Seibold, children, Bill and Laura Caudill (Seibold) of Muncie, Indiana, Greg and Jill Forman (Seibold) of Allen, Texas, and Lee and Carol Lantz (Seibold) of Lansing, Michigan; grandchildren, Jeremy and Caitlin Lantz, Justin and Sharee Forman, Joshua and Michelle Cools (Lantz), Tyler and Jill Forman, Jason and Amanda Lantz, Ritchie and Sarah Caudill, Micah and Courtney Hedges (Forman), Aaron and Heather Johnson (Lantz), Karin Caudill, Brent and Abigail Voorhees (Forman), Stephan and Jennifer Lantz, and Jonathan Lantz; 21 great-grandchildren, and siblings Donna Helgeson (Montgomery) and Richard and Judy Sawdey (Helgeson).

Dianne was born on February 23, 1929 in Minneapolis, Minnesota. She graduated from Baldwin High School in Birmingham, Michigan, before receiving her bachelor's degree in education and master's degree in home economics at Michigan State University. Dianne married the love of her life, Jack Seibold, on July 28, 1950, at St. Paul's Cathedral in Detroit, Michigan. She worked as a florist but spent most of her years teaching home economics at Mason High School.

Dianne had a passion for swimming. Through it, she met her spouse and developed a community of dear friends. A loyal Spartan alumnus, Dianne would often be seen passionately cheering for green and white at numerous sporting events. Dianne was also an avid traveler and treasured the family vacations to their summer condominium in Fort Pierce, Florida. In addition to the sandy beaches, Dianne also enjoyed time at the fishing cabin in the Canadian wilderness of Ontario, as well as visiting Hawaii, the Colorado Rockies, and numerous national parks.

Dianne would have described her greatest accomplishment as successfully raising her family. She delighted in building treasured memories with each of her children and grandchildren. Dianne enjoyed working with her husband on decorating and gardening projects. Together they created a warm and welcoming home, alive with joy and laughter. As a faithful believer in God, during her active years Dianne served her church and community in many ways, including teaching children's Sunday school and vacation Bible School. Dianne’s fun-spirited nature and servant's heart will be cherished and missed. Her family and friends find peace in the truth that she is with her God and Savior.
