Throughout his career, Marshal worked for several John Deere dealerships, building lasting relationships and earning the respect of customers and colleagues alike. Returning to Monmouth, he later joined Stockland FS as a salesman before moving to Bloomington to continue his career with Growmark. He remained with Growmark until his retirement, dedicating many years to the agricultural industry he loved. In 2000, Marshal and his wife returned to Monmouth to make their home once again.

It was a lifelong interest that remained close to his heart. Marshal and his wife, Madalyn, also shared a love of camping with their children. What began as family tent-camping adventures eventually grew into decades of camping trips with a camper, creating countless cherished memories together. A talented woodworker, Marshal found great satisfaction in building and crafting projects for family and friends. Whether restoring a tractor, creating something in his workshop, or spending time outdoors with loved ones, he took pride in working with his hands and sharing his talents with others.

Marshal was a devoted member of First United Methodist Church in Galesburg, IL, where he faithfully served as a trustee and shared his love of music as a member of the church choir.

Throughout his life, Marshal was deeply committed to serving his community and giving back to the organizations that were important to him.
