Kim Michael Grossman came into the world on Saturday, November 10, 1951, at the Elk City, Oklahoma Hospital. He was the fourth of six children of George and Lorene (Kamphaus) Grossman. He grew up and helped on the family farm southwest of Canute, Oklahoma. As a child, Kim attended Canute schools, where he graduated in 1970.

Upon graduating high school, Kim had many jobs while exploring what to do with his life, including working at a laundromat. He met the love of his life, Errol Potter, dragging Main Street in Elk City, and they began dating on Memorial Day 1971. He followed her to Weatherford to attend Southwestern State College in the fall of 1971, where he majored in the pool hall for the first year and decided college wasn't for him and began working at Harrell Meats.

Kim and Errol married on May 24th, 1974, in Elk City, Oklahoma, but continued to make their home in Weatherford. They welcomed their first child, Autumn Michelle, on June 28, 1977. Jeremiah Michael followed on December 18, 1978. Finally, the family was completed with the addition of Zachary Scott on January 9, 1984. At that time Kim and Errol determined their family was complete because they had children from A to Z. In May of 1998, Kim and Errol welcomed their first grandchild Alexis Buchelle (Ruchelle) Hoskins which brought out a new tender side of Kim. Andrew Jacob, Kaleb Michael, Victoria Madison, and Lillian Elizabeth completed his heart and really made his family complete.

Kim worked for Harrell Meats until the fall of 1978, when he started at 3M working as a line worker before eventually moving into Maintenance. During this time, Kim went back to school and achieved his degree in Engineering Technology from SWOSU in 1987. Kim stayed at 3M in the photo division through the transition to Imation and eventually Ferrania until its closing in the fall of 2006. He returned to work for Imation until its closing in 2011. In 2004, Kim and his brother Joe started raising cattle on their childhood farm with their dad. Kim kept running cattle with his wife, Errol, until his passing.

During his life, Kim was an avid hunter, fisherman, and outdoorsman. He enjoyed coaching soccer for 2 generations of his family, his son Zachary and his Granddaughter Alexis. He gained multiple surrogate sons when he started coaching Zachary's U6 team and continued to coach them throughout high school.

When Kim wasn't at the soccer field, Kim could have been found supporting his children in all their activities, hunting, fishing, playing rancher, or sharing stories with his family and friends.

Kim left the world on Sunday February 22, 2026, at his home in Weatherford, OK with his wife by his side. He is survived by his wife, Errol, of almost 52 years, his daughter Autumn Hoskins and spouse Jacob Hoskins, his son Jeremiah Grossman and partner Jennifer Dugan, son Zachary Grossman and spouse Ana Colchado, grandchildren Alexis, Andrew, Kaleb, Victoria, and Lillian, brother Joe Grossman and spouse Sharon, sister Jane Crabtree and spouse Jackie, and sister Lorri Baden. Kim is survived by numerous nieces and nephews and special friends and family members. He was met after death by his father and mother, two older brothers Rick and Randy, his in-laws Jack and Ernestine Potter, his grandniece Ashley Crabtree, and his grandnephew Henry Schattmeier.
