Charles "Chuck" William Koeck, age 62, passed away unexpectedly on December 7, 2020, at his home. Chuck was born on January 7, 1958, to Richard and Marilyn (Vander Schaaf) Koeck in Fond du Lac, WI. He attended Goodrich High School in Fond du Lac from 1972-1976. Chuck was a loving husband to his wife Mary of thirty-nine years, and an exceptional father to four children; Elizabeth (John) Van Ruiswijk, Margaret Koeck, Kathryn (Jacob) Derse and William (Lisa Bolton) Koeck and three grandchildren; Gwen Van Ruiswijk, Charles and Harrison Derse.

Chuck's first pride and joy was his family. Chuck and Mary dated for only one month before they became engaged. They married a year later on June 13, 1981. Together, Chuck and Mary were a formidable pair when raising their four children. He would drop everything to be there for them. It didn't matter if it was in the pouring rain, an ice storm or if he was in a different state; if one of his children needed him, he would be there. Chuck always enjoyed going to his children's dance recitals, sporting events, and concerts. His little pregame notes stuck inside sandwiches, wishing his children good luck, or pep talks and fist bumps prior to the first whistle was just what they needed to shake the jitters. He was their number 1 fan. Chuck worked hard to build a home in Winneconne his family would be comfortable in. His summers were spent preparing the pool for family parties and mowing the lawn for hours, which he loved doing.

Chuck had a personality larger than life which left a lasting impression on everyone he met. He was known for making people laugh so hard until they cried. Chuck gave so much to those around him.

Chuck dedicated his life to teaching children. After graduating with his bachelor's degree from University of Wisconsin- Oshkosh in 1989, he taught for the Oshkosh School District at Washington Elementary and Carl Traeger Elementary for 25 years. His non-conventional, humorous ways of teaching brought smiles to everyone's face. The impact he had on his students and colleagues made the world a better place.

During retirement he started making caramels as a hobby, but it quickly grew into a successful business venture, Charlie's Caramels, LLC. He was very proud of his candies and so meticulous about the quality of every batch. He left a little bit of his heart in each piece of candy.

Chuck loved to cook and bake; he made sure that no one ever went hungry. He was always trying new recipes, but had his homemade favorites like chip dip, pretzel salad and Thanksgiving in a bun. Chuck always managed to put a little extra love and joy into his baking, cooking and grilling. Chuck's specialties were often requested by his nieces and nephews at family gatherings, which he graciously did to make them happy.

Chuck loved to play board games and card games like Parcheesi and Canasta with anyone he thought he could beat, making up rules as the game was in progress or even threatening to call the game manufacturer for a rule clarification. Chuck also loved getting together with his group of Sheepshead guys where they played some serious cards and shared some not so serious jokes.

Along with his wife, children and grandchildren, Chuck is survived by Rick (Nancy) Koeck of Prairie du Sac; Michael (Laurinda) Koeck of Fond du Lac; Debra (Chuck) Rosen of Antioch, IL; Ann (Michael) Mielke of Fond du Lac; Jim (Jane) Klein of Appleton; James (Barbara) Schneider of Fond du Lac; Joseph (Becky) Schneider of Fond du Lac; Catherine (John) Davies of Danville, CA and numerous nieces, nephews, great-nieces and great-nephews.

Chuck was preceded in death by his parents, Richard and Marilyn (Vander Schaaf) Koeck; and in-laws Cletus and Ruth (Steffes) Schneider.

A funeral service will be held on Saturday at 1:00 p.m. at the church. Burial will follow in the Riverside Cemetery, Oshkosh.
