Helen Margaret Underberg was born on August 19, 1952, to Irwin (Slag) and Betty (Jindrich) Underberg in Mason City, IA. She spent the first 6 years of her life living on the farm outside of Swaledale, IA until the family moved to Eagle Grove, Ia. She passed away on September 8, 2021, at Pillars Hospice in Oakdale, MN. During these last few months, she was blessed to have her good friend, Linda, by her side helping to care for her needs.

Helen graduated from Eagle Grove High School with the class of 1970. She then attended Iowa Central College and Iowa State.  It was while she was living in Ames that she met John Tressler. They were united in marriage on October 11, 1975. They then moved to the Twin Cities.  To this union they were blessed with Jennifer and Tom, she was blessed with two bonuses, RaeAnn and Greg.

They spent many weekends enjoying, friends boating and camping out on the river. Many have remained lifelong friends. John and Helen later went their separate ways. 

She was extremely blessed in her relationship with Ron Schnegelberger. They spent many hours on road trips and motorcycles rides looking at the beautiful scenery and just enjoying time together. If they weren’t out riding, they could be found on the weekends working on one of her many projects. She liked her projects. Ron has been by her side loving her faithfully through many health issues. 

Throughout her life she held different jobs, she worked at a coat factory, she did in home childcare when her children were younger and finished her working career at Sportsman’s Guide. 

Her greatest joy has been her family. She loved her family, her children and their spouses, her grandchildren and hosting family gatherings. She also loved getting to spend time with her siblings. 

She will be remembered as loving people fiercely and always looking to the good in the other. All who have known her have been blessed. As she told her family often enough, she not only had a good life, she had a great life.
