Calvin L. Osinga

Calvin “Cal” Lee Osinga, age 76, of Denmark, died peacefully at home on Friday, May 30, 2025, after living with esophageal cancer for 10 months. He was born March 6, 1949, in Racine, WI to the late George and Dorothy Osinga. Cal was a well-rounded athlete who remained active throughout his life. During his years at Horlick High School, he played on the football, basketball, baseball, and hockey teams. After graduation, Cal served in the U.S. Army Reserve from 1969-75. At the same time, he was beginning a career as a draftsman, creating technical drawings and plans for machinery at Tomco in Racine. Tomco is also where Cal met his wife, Val. They married in 1970, on a winter’s day so cold that Cal’s car wouldn’t start, and he had to have a friend drive him to the church. A few years later, Cal and his growing family moved to Green Bay, when Cal accepted a position at Paper Converting Machine Co. (PCMC). Cal stayed with PCMC for more than 20 years, rising through the ranks to become a respected leader and manager. Cal loved living in the country, surrounded by nature, where he could peacefully putter on one of his many projects, or sit quietly on the deck, watching the birds, deer, and other wild animals that are common visitors. He also had a fondness for vintage muscle cars, especially his 1969 Ford Mustang, which he spent years customizing into the perfect “rat rod.” A skilled craftsman, Cal was extremely proud of his home, which he built 50 years ago and where he lived until the day he passed. Cal often built things for his family as well, including a small cabin for his kids to warm up in after ice-skating on the pond, downhill skis fashioned from an old toboggan, and even a homemade zip line. Cal was an avid golfer who began most days with a round at Wander Springs, where he was a longtime member. He was also an enthusiastic birder. Along with his wife, Cal kept detailed bird journals, tracking the annual migration patterns of the geese, sandhill cranes, and songbirds that frequent their property. Cal is survived by his wife of 55 years, Velma “Val” Osinga; their children: Cheryl (Thomas) Breuer, Jeff Osinga, and Laura Osinga; his granddaughter, Juliet Osinga-Schlei; his sister, Mardell (Peter) DeMarco, and brothers David (Susan) Osinga, Randall Osinga, and Dale Osinga; along with many nieces and nephews. Cal is preceded in death by his parents. A service celebrating Cal’s life will be held on Thursday, July 10, 2025, from 2-4 p.m. at Hamlet Creek, 3562 Finger Road. A Time of Reflection and words of Remembrance will be held at 4:00 p.m. with Chaplain Dawn Sundstrom officiating. Cal’s family would like to express their heartfelt gratitude to Mark Dehnel, PA-C, with Bellin Health in Denmark, WI; Dr. Tyion Torres and Dean Weycker, APNP, and the entire Bellin Health Cancer Center team in Green Bay, WI; Dr. Gustavo Fonseca and Tiffany Eddins, APRN, and the caring staff at Florida Cancer Specialists in Lecanto, FL; and Dr. Robert Matthias with Florida Orthopaedic Institute in Ocala, FL; for their compassionate support of Cal.
