Obituary
Age 78, of Portage, passed away on August 5, 2025, at her home, surrounded by family. Carol was born in Grand Rapids, MI, the daughter of the late Leo and Ruth (Karsies) Yonkers. She had a heart for service, and the joy of the Lord was her strength.
Carol was a multi-talented woman who graduated from Calvin College and worked as a lab technician for Bronson, Borgess, and St. Mary’s Hospital. While raising her children, she served as the Vice President of Accounting for her family’s business, Bos Construction, and quickly rose to the Director level with Mary Kay Cosmetics.
When her children were grown, Ed and Carol started and ran Worldwide Lab Improvement for more than thirty years, also serving as full-time missionaries. She had a passion for music and was an accomplished pianist and organist. She began piano lessons at 4 yrs old and chose to use her God-given skills throughout her life. As early as high school, she was hired to be the main organist at a church and continued in music leadership, including 11 years as the Music Director at Third Reformed Church (Centerpoint). Carol was most recently a member of Calvary Bible Church, where she will be deeply missed.
Carol loved her family and was especially proud of her children, grandchildren, and great-grandchildren. She leaves behind the legacy of a life well lived.
On June 6, 1967, she married the love of her life, Edwin “Ed” Bos, who survives. She is also survived by two sons: Steve (Pam) Bos and their children—Andrew (Emily) Bos, Emily (Will) Hollis, Zach (Melissa) Bos, Hannah (Matt) Baker, Rachel (Jack) Rex, Kate Bos, Jeremiah Bos, Isaac (Kaitlyn) Bos, Josiah Bos, Nathan Bos, Levi Bos, and Abigail Bos; and Jeff (Megan) Bos and their children—Jack Bos, Leah Bos, Luke Bos, Eli Bos, Tyler Bos, and Noah Bos.
Also surviving are six great-grandchildren: Micah, Adalynn, Ellie, Daniel, Mikayla, and Olivia; her brother, Jack (Deb) Yonkers; brother-in-law, Dan (Esther) Bos; and brother-in-law, Tom Chicklon. She was preceded in death by her parents, Leo and Ruth Yonkers, and her sister, MaryJo Chicklon.
” My faith has found a resting place not in device or creed” well done carol. I will miss your playing skills on earth,but heaven is blessed as. You rejoice in heaven. Your picture says it all there is JOY in the Lord.Blessings on your family as you have left a legacy for them to follow.
Jeff, Megan, and family: I’m so sorry for the loss of your mom and Grandmother. Thinking of you all and sending prayers and love to you.
My heartfelt condolences to Ed, Steve, Jeff and family. I first met Carol in the late 70’s when we were backing Gospel Singer, Lynnelle Pierce. We were members of Third Reformed Church back in 1990 when Carol asked me if I would like to play drums in a worship team she was forming. That first worship team consisted of Carol on organ, Steve on trumpet and me on drums, as I recall. I have many great memories of performing with Carol and watching her boys grow up. The Heavenly choir just got an upgrade!
So sorry to see of Carols passing. I grew up in the Maestro Acres neighborhood and babysat her boys quite regularly. Carol was always so nice and talked to me like an adult, not just a neighbor kid. I always enjoyed babysitting at their house on Shuman. May you rest peacefully in your Father’s arms. My sympathies to the entire family. Cindy Gernaat
I have very good memories of Ed and Carol at Bronson. My sympathies, Ed, to you and your family.
I met Carol and Ed more than about twenty years ago as part of TECH. She and Ed seemed to be fine people, but most importantly strong fellow Christians. I had forgotten about the work I did for them many years ago until I went to their website and saw the logo which I designed for them. I would be sad only for Ed and her family. As for Carol, she now knows no imperfections, aches, pains, and struggles of our life. Love you, Ed and Carol! Dr. Ron
