Obituary

Marsha Mary Koski, age 80, of Saginaw, passed away peacefully at home surrounded by family on Saturday, February 21, 2026.

She was born on June 25, 1945 to Max and Ethel “Elaine” Ackerman in Saginaw, Michigan.

Throughout her life, Marsha worked at General Motors - Nodular, Grey Iron, Malleable Iron, and Flint Truck and Bus.  She enjoyed trips to the casino, playing Keno, scrabble and eventually Words with Friends, and bingo with family and friends. She was always up for watching a good movie.

In her own words she raised and educated three beautiful amazing daughters in which she was so proud of and claimed as her greatest accomplishment.  She lived and died on her own terms.

My much older sister was one of Marsha‘s best friends. I remember going over there so many days and she and Chris Madigan and Nancy and lots of other from GM would sit around the round tables in the kitchen and gossip about General Motors politics mostly. Marsha was usually curling her hair at the same time. The pool was always open in the summer for the kids to swim. The while house was really a kids paradise. There was always something for kids to do. But nobody can forget the Halloweens. Marsha did up the whole house in Halloween ornaments and we all went trick-or-treating in the neighborhood with great treats. It was so fun. Marcia was always loving and kind to everybody that entered their house, especially children. I always will remember her fondly. - Karla Lopez.
