Zach Weprin is the President of Certified Cultivators, a Level 1 Cannabis Cultivator and Processor with integrated retail operations based in Dayton, Ohio. A lifelong entrepreneur, Zach’s introduction to cannabis came after being diagnosed with Crohn’s disease—an experience that led him to discover the potential of cannabis and sparked a personal and professional passion that continues to shape his work today.

Under Zach’s leadership, CERTIFIED became one of the first licensed operators in Ohio’s medical cannabis market, launching operations in 2019. Drawing from his background in the food and hospitality industry, Zach brings a deep commitment to quality, efficiency, and consumer experience. That foundation, combined with his entrepreneurial roots—nurtured through a family legacy of business ownership—led Zach to partner with his father in building CERTIFIED from the ground up.

Zach continues to guide the company with a focus on integrity, innovation, and delivering premium cannabis products to the Ohio market.
