Mandy’s interest in construction grew not only through her personal connection to the business as Mark’s wife but also through her involvement in business development, marketing, and now, employee development. She’s proud to support this dynamic workforce that requires tactical talent and a dedication to the details and risks involved in building structures. Her favorite part of the job is collaborating with others—whether it’s brainstorming new ideas with the marketing team or solving challenges with leadership. She enjoys being part of a team where different perspectives come together to innovate and find effective solutions.
Matt’s journey into construction started with a deep appreciation for architecture—especially timeless stone buildings and classic wooden taverns. He was drawn to the idea of creating structures that serve communities and stand the test of time. As a Marksmen GC intern, he quickly learned that construction is more than just building—it’s problem-solving, critical thinking, and teamwork. His most memorable project, Fire Station 123, came with its fair share of challenges, but overcoming them made the final result even more rewarding. His advice to interns? Stay humble, ask questions, and never stop learning. When challenges arise, he leans on his faith to stay focused, finding clarity and strength through prayer and reflection.
Josue’s passion for construction began at a young age, inspired by watching his sister build custom homes in partnership with a local architect. That early exposure—paired with his faith—laid the foundation for a purpose-driven career. At Marksmen, he thrives on collaboration, whether he’s coordinating a jobsite or connecting with students. His approach to work is deeply rooted in honoring God, and he encourages others entering the field to trust in the Lord, learn from their mistakes, and grow through every experience. For Josue, prayer and scripture provide the focus and peace needed to lead through challenges with clarity and grace.
