John Karl Feuerstein

May 3, 1943 – November 4, 2026

John Karl Feuerstein, 83, passed away peacefully on November 4, 2026, in Fenton, Michigan, leaving behind a lifetime of memories, questionable jokes, and a family who will miss him dearly.

Born in Chesaning, Michigan, to Leonard and Isabel Feuerstein, John graduated from St. Michael’s High School and earned both his bachelor’s and master’s degrees from the University of Michigan–Flint. Drafted into the U.S. Army, he served as a medic, a role he took great pride in. He later spent more than 30 years as a chemical engineer at General Motors, a career he genuinely loved.

In 1969, John married Connie, and together they raised two daughters. He enjoyed pheasant hunting, fishing trips to Canada, gardening, collecting vintage cars and coins, Michigan football, and writing his Back in the Day column for the Tri-County Times.

John loved traveling the world with his family, provided everyone was committed to getting their money’s worth. His adventures took him from Europe to Hawaii, Alaska, and countless cruises, creating memories his family will treasure for generations.

Perhaps most memorable was John’s mischievous sense of humor. With his perfectly timed, often inappropriate comments, he delighted in making people laugh, blush, or question whether he’d really just said that.

John is survived by his daughters, Kamee Stiles (Pedro Bandera Vazquez) and Kelly Hiler (Chris Hiler); grandchildren, Kayla Stiles (Seth Pefley), Sean Stiles, Nicholas Stiles, Madison Hiler, Macy Hiler, and Briella Hiler; sister, Nancy Stefanic (Dave Stefanic); and brother, Denny Feuerstein.

He was preceded in death by his wife, Connie Feuerstein; parents, Leonard and Isabel Feuerstein; and sister-in-law, Clara Feuerstein.

Affectionately known as “Creepa” to his grandchildren, John leaves behind a family who will forever cherish his humor, adventures, and unwavering love.

And if he managed to make you just a little uncomfortable along the way, well, Creepa would have considered that a life well lived.
