Justin is a seasoned professional in landscape, agriculture, water distribution, and irrigation technology, holding a B.S. in Agricultural Sciences, Landscape Contractors license and industry certifications such as an Irrigation Auditor.

Aaron Madsen’s career began with a simple but powerful foundation: design matters. After earning his degree in Architecture from the University of Nebraska, he stepped into the landscape design and construction industry with a designer’s mindset and a builder’s work ethic. What followed has been more than 20 years of hands-on experience learning how great projects move from paper to performance.

Over the years, Aaron discovered that irrigation—often overlooked when done well—is one of the most critical systems in any landscape. A thoughtfully designed irrigation system protects the integrity of the design, preserves resources, and determines long-term success. That realization shaped the path that led him to Hunter Industries.

Today, as Specification Manager for the Sacramento Valley and Northern Nevada markets, Aaron works alongside architects, designers, municipalities, and public agencies to ensure irrigation systems are not only specified correctly, but thoughtfully integrated. Representing a global leader in residential, commercial, and golf irrigation solutions, he serves as both technical resource and trusted advisor. Aaron is especially passionate about education.

Whether guiding a designer through system layout, helping troubleshoot field challenges, or discussing best management practices, he brings clarity and practical insight to every conversation. His approach blends architectural perspective, field experience, and a commitment to water stewardship—helping communities implement solutions that are efficient, sustainable, and built to last.
