Zane & Heather Diersen
Zane and Heather Diersen's story begins in the small town of Manning Iowa. They first crossed paths in high school, thanks to Zane's friendship with Heather's brother, sparking a relationship that blossomed into beautiful marriage and the joy of raising three children in Grimes, Iowa. After years of dedicated work—Zane spent 17 years with Lomar Distributing while Heather ran a daycare—the couple decided to channel what they had learned growing up in rural America into a new venture, launching Diersen Construction LLC, it was a hit, thanks to their top-tier remodeling services and genuine customer service. However, after recent devastating tornado seasons in Iowa, they felt called to research how to better protect people from such disasters. This led them to recognize the significant need for quality storm shelters in the state, culminating the creation of Ironclad.
