Mark McCann

Mark McCann, age 68, passed away peacefully surrounded by his loving family on Thursday, Oct. 8, 2026, after a long, valiantly fought battle of 11 years with cancer.

Mark grew up in Grafton, Wis.  He lived there for many years and it is where he met his loving wife of 43 years, LaVonne Henig.  They had two children, Tyler Gensmer and Sara McCann.

He was a dedicated, highly skilled machinist at Gilman Precision for more than 35 years. His career allowed him to achieve his No. 1 objective in life to be a provider and protector of his family.

Many people will remember Mark as a man with a love for the outdoor life.  Fishing, hunting and camping with family and friends were high on the list of his passions in life. He will also be remembered as a Girl Scout dad. He was the stranger who would always offer help and the guy who would offer you the shirt off his back if he thought you needed it.

He will be remembered fondly by acquaintances and friends who stood by him. We also would like to thank Dr. Syed Abutalib and his team as well as everyone at St. Luke’s who cared for Mark and fought the fight alongside of him.

A celebration of life will be held for Mark McCann at a soon-to-be-determined date. Please check www.muellerfuneralhome.com for updates.
