Our Expertise
Get to know us:
Welcome to IA Supply LLC — your trusted partner in drainage solutions and beyond.
We’re David and Lindsey, a husband-and-wife team proud to carry on a family legacy of hard work, service, and community commitment. IA Supply isn’t just a business to us—it’s personal. We’re taking the reins from David’s aunt and uncle, Cindy and Ed Hofacker, who built a reputation for reliability and strong relationships across Wisconsin. Our mission is to honor that legacy while bringing fresh energy to meet our customers’ evolving needs.
David brings 13 years of hands-on experience in construction project management, with a deep understanding of what it takes to keep jobs on track and on budget. He knows how vital the right products are, and how important it is to get them to the right place, at the right time.
Lindsey, an ICU nurse by profession, brings her own brand of precision, care, and problem-solving—skills that are just as essential in business as they are in healthcare.
Together, we balance grit and grace, and we’re committed to making your experience with IA Supply as seamless and dependable as possible.
Whether you’re a contractor, landscaper, or farmer, we’re here to provide high-quality drainage products and personalized service that keeps your projects flowing smoothly.
Let’s build something great—together.
