My dream to start an irrigation company has been 25 years in the making. My background in law enforcement gave me an appreciation for the value of thorough training and integrity, and I am motivated by this to provide quality irrigation systems and professional service.
Continuing to enhance my knowledge and personal growth is a priority, including being at the forefront of the latest innovative technology. My certifications through the Irrigation Association include CIC (Certified Irrigation Contractor) and the CLIA (Certified Landscape Auditor), backflow preventer testing certification through ABPA, Missouri State Commercial applicators license to apply lawn chemical applications.
I train Irrigation Consultants throughout the United States and have taught in India. It is my desire to share my experience and knowledge to train individuals that will provide their customers with the highest quality and best practices in irrigation installation and service.
It is with utmost respect and enthusiasm that I join my partners that share the same focus on providing the highest quality irrigation training, consulting and irrigation water management in the world!

I haven't seen it all, but I’ve seen a lot in my almost 30 years in the landscape irrigation industry! Over the years, I’ve been a golf course superintendent, installer, service technician, auditor, designer, water manager, irrigation instructor, and consultant. I’ve worked for large irrigation companies, irrigation consultant companies, a major manufacturer, and have run my own business.
In 2002 I made a commitment to trying to improve the landscape irrigation industry as an irrigation instructor and curriculum developer for Rain Bird Services Corporation. As I earned my certifications through the Irrigation
Association, I also transitioned to the role of Landscape Irrigation Consultant, focusing on efficient irrigation design and auditing. I also worked with the Irrigation Association as Chair of the designer common interest group as well as an irrigation committee member of the Minnesota Landscape and Nursery Association.
Over the years, my irrigation work has brought me all over the United States, Canada, the Caribbean, China, and Australia. I have performed many hundreds of irrigation audits and evaluations. I have created hundreds of efficient irrigation designs for residential, commercial, and large commercial properties.
I am excited about this new chapter at Global Irrigation Solutions. We come together to create a powerful team committed to making the industry better.

In the late 1990s, I started my irrigation career by performing maintenance crew work at a golf course in Hudson, Ohio. While earning my degree in agronomy and golf management at The Ohio State University, my passion grew and helped me to quickly advance to a golf course superintendent position with The Dunes Golf & Tennis Club in Sanibel Island, Florida. At the same time, opportunities arose that led me to obtain a contractor’s license and start my own irrigation company in Fort Myers, Florida. After operating my company for nearly 18 months, I wanted experience with larger projects and opportunities to grow faster than what a small business would allow. To accomplish this, I closed my company and took a position as an irrigation design engineer with Stahlman-England Irrigation headquartered in Naples, Florida. In this position, I was responsible for all design and estimating
activities for their field office in Sarasota, Florida.
In 2008, as the construction market took a major downturn, I took my first step in helping to elevate the irrigation industry by accepting the position of the technical trainer with Rain Bird. In 2010, I was promoted to the senior technical trainer position responsible for three education programs offered by Rain Bird Training Services. As a trainer with Rain Bird, I had the privilege of training irrigation professionals in the United States, Canada, Mexico, China, Australia, Thailand, Scotland, England, Vietnam, the Philippines, and Jamaica. Through the power of technology, I was also able to train in many Eastern European countries through internet-based live-streaming sessions. I enjoy teaching so much that I returned to school and earned another degree in technical education from Northern Arizona University.
Bringing nearly 24 years of experience from all sides of the industry and multiple Irrigation Association and other industry certifications to Global Irrigation Solutions, I am looking forward to facing new challenges. I await the opportunity to improve water efficiency across the globe.

I have been in the golf course industry for 41 years, performing everything from golf course setup, maintenance, irrigation repair, and installation. For the last 33 years, I exclusively supported the Rain Bird product line installing, servicing, and troubleshooting systems in several states. During my career, I was the manager for Boynton Pump and Irrigation Supply in Stuart Florida, President of Southwest Irrigation (Rain Bird Golf Distributor) in Tulsa Oklahoma, irrigation manager at Admiral’s Cove in Jupiter Florida, and an irrigation technician at a few clubs in Oklahoma and Louisiana. Immediately prior to joining Global Irrigation Solutions, I had been providing factory direct
service in South Florida and the Caribbean as a Rain Bird employee since 2008.
Golf course and commercial irrigation has been my life and I really enjoy getting paid to have fun every day. I’m proud to be a part of the GIS team and ready to continue to provide solutions to my current friends and the new ones we will make along the way.

As a newcomer to the ever-evolving irrigation industry, I am fueled by a curiosity and an eagerness to learn and grow within this field. Outside of my professional pursuits, I find joy in spending time with my two-year-old daughter, Bryn, whose laughter and wonder at the world inspire me daily. Beyond work and family; I have a love for the great outdoors, indulging in activities such as fishing, camping, and boating, where I can connect with nature and unwind. An animal enthusiast at heart, I cherish the companionship of creatures both big and small and dedicate time to training my dogs, fostering a bond that brings joy and fulfillment to my life.
