Alan Edward - Education & Training Director

Education Director Alan Edwards, a native of Cincinnati, received his undergraduate degree in Environmental Science and History from Miami University in Oxford, Ohio and his Masters in Community Planning from the University of Cincinnati’s School of DAAP. While in graduate school he served as a Peace Corps Paul D. Coverdell Fellow and also a National Parks Service, Rivers Trails and Conservation Assistance Fellow. He served in Peace Corps Senegal, West Africa from 2009-2011 as an Agroforestry Extension agent. In Senegal he helped small scale subsistence farmers implement more sustainable agriculture practices through implementing agroforestry techniques. This time in Senegal helped cement his desire to help people in need and put into practice more sustainable practices like permaculture back home.

Mackenzie Griesser - Office Manager

Mackenzie is a Cincinnati native who graduated from the University of Cincinnati in April 2016 with a BS in Environmental Studies. She first learned about Groundwork Cincinnati when Alan took her class out to do water quality monitoring on the Mill Creek. Later that year, she and another student worked with Groundwork and Outdoor Adventure Clubs of Greater Cincinnati to vet them into UC's Environmental Studies capstone program. Shortly after graduating, she joined the Groundwork team as an intern. At the beginning of 2017, she joined the staff as the Office Manager and was appointed as the Secretary for the Board of Directors shortly after. When she isn't working at the office or one of Groundwork's restoration sites, you can find her outfitting local adventurers at Roads Rivers and Trails or backpacking at Red River Gorge.
