Roesink Consulting is a family-owned irrigation auditing company founded by husband-and-wife team Gregg and Sabra Roesink.

As Certified Irrigation Auditors, we are passionate about helping property owners, builders, landscape contractors, HOAs, and municipalities maximize water efficiency while protecting the health and longevity of their landscapes.

Gregg brings decades of experience in the irrigation and landscape industry, providing a deep understanding of how irrigation systems are designed, installed, maintained, and operated in real-world conditions. His extensive field knowledge allows us to identify issues that can impact system performance, water use, and long-term reliability.

Sabra oversees the auditing, reporting, and client coordination side of the business, ensuring every project receives the thorough documentation, attention to detail, and responsive communication our clients have come to expect. Together, we combine technical expertise with a commitment to delivering clear, practical recommendations that help clients make informed decisions.

As independent third-party consultants, our role is simple: provide objective evaluations and accurate reporting. We do not perform installations or sell irrigation products, allowing us to focus solely on the findings and recommendations that best serve each project.

Whether we're evaluating a residential landscape, a commercial development, or a large-scale community project, our goal remains the same—to provide professional irrigation audits that improve efficiency, conserve water, and give our clients confidence in their irrigation systems.

We appreciate the opportunity to serve our clients throughout California and look forward to helping you achieve a healthier, more efficient landscape.
