Dave Spillman

Co-Founder & Chief Technical Officer

Dave Spillman serves as a Co-Founder and Chief Technical Officer. He nurtures the company’s relationships with its many valued clients, helps guide lighting system designs and technology integration, and supports research and development.

An engineer by trade, Dave has first-hand knowledge of the many growth and efficiency struggles faced by commercial growers. He began working in the legalized cannabis industry in 2013, as one of the original founders of High Mountain Health, a leading medical cannabis grower and dispensary in Arizona that is respected nationwide for its commitment to utmost quality, efficiency and environmentally friendly practices. Spending more than three years researching photo science and the effects of different types of light on cannabis, he designed the cultivation site to operate like a factory, while implementing systems that would ensure a quality product synonymous with smaller operations. Dave spearheaded a scheduled production system supported by the building design, and then continued to refine the grow operation by devising and employing new technologies that would reduce production costs while increasing yields. He quickly realized that LED lighting was a critical component in achieving these goals, which led him to co-founding ProGrowTech, which created the first industrial-grade lighting tool specifically designed for horticultural use.

An embodiment of ProGrowTech’s “developed by growers for growers” philosophy, Dave offers a deep understanding from both the cultivation and business perspectives. He knows exactly what challenges and opportunities cannabis businesses face in an increasingly competitive market – and the tools needed to make their businesses stand out. Dave helps ProGrowTech clients meet their short- and long-term goals through cutting-edge equipment and a wealth of knowledge. He continues to serve as operations manager at High Mountain Health, overseeing the commercial cannabis cultivation operation. This dual role allows him to be actively involved in pressing LED science to the limit, constantly evolving the technology to create better results for growers, while helping the company maximize efficiency while managing costs.

Early in his engineering career, he realized a desire to focus on smart building that would be environmentally friendly. With process engineering and material science at the cornerstones of his calling, he has married the world of design with environmental conscientiousness and efficient building, becoming an industry trailblazer. Focused on green building before it became a buzzword, Dave was president at Spillman Custom Homes for more than 21 years, where he designed and built high-end custom homes and commercial construction projects to be carbon neutral before the concept became wide-spread.

Dave studied toward a Bachelor of Science in Mechanical Engineering from California State University in Chico, and pursued both manufacturing and mechanical engineering at Yavapai College in Prescott, Ariz. With a penchant for nature, he’s a student of the outdoors, as well. A Grand Canyon River guide for more than 30 years, Dave is also a commercial pilot, briefly running a small air charter business and member of the Aircraft Owners and Pilots Association. He also sits on the board of the Flagstaff Alpine Ski Team.
