Zach Robinson | Executive Director

Zach Robinson has more than doubled, every year, the number of youth served and the financial growth of Spark-Y since he became Executive Director in 2013.

Committed to his staff and the youth population they serve, Robinson seeds principles of entrepreneurship and empowerment into his leadership approach. As a result, hundreds of interns and student participants have gone on to start their own businesses, obtain jobs, or are inspired by sustainable business practices for their future.  As an organization, this has contributed to a culture of progressive growth - students becoming interns, interns returning as leaders, leaders enterprising to staff positions, and staff collectively expanding the mission and impact of Spark-Y.

Robinson is passionate about creating win-win relationships with community, corporate and financial partners. These strategic partnerships create meaningful experiences for youth, while providing value for our partners. As a result, Spark-Y and their partners continue to launch youth-engaged innovative and sustainable projects, including the first in-restaurant aquaponics system and the greenest school campus in Minnesota.

Sam Menzies, Spark-Y Operations Director, leads sustainable systems for the organization: in-classroom programs, community / off-site initiatives and a commercial-scale urban aquaponics system at our Minneapolis office. Exemplifying sustainability and entrepreneurship in-action, Menzies creates systems that generate produce and monetary resources, using available and re-purposed materials, while eliminating waste-streams. The simplicity and ingenuity of Menzies’ systems design are taught in classrooms, showcased at the Urban Agriculture Lab, and integrated into every Spark-Y project.

Michelle Chmura
Education Facilitator

Innovator, lifelong learner, compelling presenter

I come from a background in astrophysics and geology from the University of Minnesota. When looking at the possibility for life in our universe and Earth-like planets, I began to understand just how special and unique our home planet is in comparison. While a planet made of diamond, or sulfuric volcanoes would be neat to explore, none of them contain the conditions necessary for life. With Spark-Y, I hope to educate future generations for sustainable living to keep our Earth habitable.
