Sid Sinnema, 81, of Rockford, formerly of Bozeman, Montana, was called home to be with his Lord and Savior on Tuesday, July 14, 2026.
Born in Bozeman, Montana, to the late Jake and Sadie Sinnema, he was raised on a farm where he developed a strong work ethic that remained a defining characteristic throughout his life. In 2014, he moved to West Michigan to be closer to his family, cherishing the opportunity to spend more time with those he loved. Sid also proudly served his country in the U.S. Army National Guard, carrying with him a deep sense of patriotism and commitment.
Blessed with a servant's heart and an unwavering love for his family, he was a fierce protector of those he loved and a man whose generosity was evident through the countless ways he shared his time and talents with others. Over the years Sid actively served his church, as elder and deacon, Bible study leader, and in many other capacities. A special highlight of Sid’s life was travelling with his wife Aurene to Tanzania to build a helicopter hanger for a missionary they supported from their church. Whether serving community organizations or lending a helping hand, he found joy in making life a little better for those around him.
He possessed an exceptional mechanical mind and was remarkably resourceful, able to solve almost any problem placed before him. Following his retirement, he worked at a local hardware store in Bozeman, where customers frequently sought him out by name, knowing he could quickly identify the exact part or tool needed for any project. His knowledge, patience, and willingness to help made him a trusted resource and a friend to many.
He also enjoyed traveling and camping over the years, creating lasting memories through life's adventures. Sid also enjoyed woodworking, creating beautiful keepsakes for his family and friends to enjoy. Yet, above all else, his greatest joy was found in his family. His steadfast love, strength, servant's heart, and faithful example will be treasured by all who had the privilege of knowing him.
He will be lovingly remembered by his wife of 60 years, Aurene; children, Michael Sinnema; Laurie (Tim) Rodriguez, Brian (Mashawn) Sinnema, Callie (Cory) Westerlund; grandchildren, Hannah and Jacob Rodriguez, Aiden (Joelle) Brunin, Sophia Sinnema, and Carson (Sammi) Johnson, great grandsons, Cole and Kian Johnson; siblings, Gerald and Mary Sinnema, James and Jan Sinnema; sister-in-law, Carrie Sinnema, brother-in-law and sister in-law, Dennis and Judy Stoel; several loving nieces and nephews. He was preceded in death by his grandsons, Gavin Brunin, and Connor and Cameron Johnson.

Memorial services will be held at 11 a.m. Tuesday, July 21, 2026 at Matthysse Kuiper DeGraaf Funeral Home, 1601 Post Drive NE, Belmont, with Pastor Josh Williams officiating.  Relatives and friends may meet the family Tuesday from 10:30 - 11:00 a.m. prior to the service at the funeral home.  A luncheon will be held immediately following the service with a continued time of fellowship and remembering.
