Mark K. Sibbing – Hansen-Spear

Mark Kent Sibbing, age 75, of Quincy, died on Sunday, March 30, 2025 at 7:02 pm, after a short stay at Quincy Healthcare and Senior Living.

Mark was born on July 16, 1949, a son of Earl Phillip and Rosalie Jansen Sibbing. On March 3, 1972, he married Mary Ann Jennings in Quincy. She survives.

He was a graduate of Seymour High School in Payson, Illinois. He served in the United States Navy from March 24, 1968 until December 13, 1969, most of that time spent at sea on the USS Yorktown, an Essex-class aircraft carrier.

Mark worked at Gardner Denver for 17 years before transitioning to a mail and delivery role at Quincy Medical Group, where he worked for 20 years, until his retirement. He enjoyed his time at Quincy Medical Group, especially for all the people he got to see and interact with daily.

Mark was a family man who had a calm presence, a cheerful demeanor, and a knack for telling great jokes. He never missed a ballgame or swim meet when his children were growing up. He loved to travel, and looking back, his favorite trips were the family trips when his children were young.

An avid deer hunter and fisherman, Mark was also skilled at tinkering and always had a project or task he was working on. If a project or task stumped him, Mark would figure out a way to accomplish it.

Survivors in addition to his wife of 53 years, Mary, include two children; Missy (Tom) Mitchell of Quincy, and Matt (Ellee) Sibbing of Lee’s Summit, MO; four grandchildren, Maddie, Kylie and Brady Sibbing, all of Lee’s Summit, MO, and Miles Mitchell of Quincy; two brothers, Mick (Caryl) Sibbing of Quincy, and Tony (Kelly) Sibbing of North Kansas City, MO; two sisters, Eileen (Roger) Sullivan of Quincy, and Sue (Rick) Lewis of La Grange, MO; two brothers-in-law, Marvin (Barb) Jennings of Frankford, MO, and Larry (Melinda Taylor) Jennings of Marion, IA; three sisters-in-law, Julie Dawson of Kansas City, MO, Carol (Tony) Fink of Topeka, KS, and Hazel Jennings of Atchison, KS; numerous nieces and nephews.

He was preceded in death by his parents, his father- and mother-in-law, Darrell and Rosie Jennings, and two brothers-in-law, Ron Jennings and Jim Dawson.
