Experience is a valuable resource, and whether it is utilized in the custom building of a door, or imparted through mentorship of a colleague, Jack Sims is a wealth of knowledge for the Door production team.
For many across Lumbermen’s, the Door Division would not feel the same without “Jack’s Shop.” That’s the space on the production floor where Jack Sims has spent more than a decade applying his deep technical expertise, mentoring teammates, and keeping work moving smoothly.
Jack has been in the industry since he was 17 years old, and joined Lumbermen’s over a decade ago, now serving as a Custom Door Builder on the production floor. Known for being extremely technical, helpful, and patient, he has become a go-to resource for solving challenges and training the next generation of employee-owners.
In describing his work, Jack says: “Cladding, cut down screens, impression storm doors. Carpentry skills for building things the shop needs—door repairs also.”
But for Jack, the true satisfaction comes from teaching and mentoring: “I like training new people, sharing my knowledge, and seeing them succeed. One of my favorite processes is to show someone why we do a certain process and not just how it needs to be done. Also sharing company information with new employee owners.”
Jack recently shared that he plans to retire in 2026. While it will be difficult to imagine the shop without his steady leadership, he has certainly earned the opportunity after a lifetime of hard work. The good news is that he plans to return part-time to keep his skills sharp—and will even be working alongside his wife, who is also part of the Door Division.

Jack’s contributions have left a lasting mark on both the products we build and the people he has trained. His legacy of knowledge, craftsmanship, and mentorship will continue shaping Lumbermen’s long after “Jack’s Shop” welcomes its next chapter.
