Dan Engel, Stewardship Coordinator

Dan hails from Grand Ledge, Michigan. He began visiting southwest Michigan over a decade ago, and recently moved to Sawyer to raise his daughter near family. His passion for the outdoors began early while he waded in the local creek and chased deer in the neighborhood woods. He nurtured this passion by studying biology at Calvin College and earning a master’s in conservation ecology at the University of Michigan. Dan’s work experience has varied from a conservation crew with the City of Ann Arbor to a wetland research team with the US Geological Survey, from teaching high school math and science in Honduras to teacher aiding at a K-12 school in Milwaukee. Through all these adventures, his mission has remained the same: to use sound science to protect natural areas for the benefit of people and wildlife, and to pass on that ethic to others.

In his free time, Dan enjoys hunting, hiking, bird watching, kayaking, running, and playing soccer. Even better is sharing these experiences with his family!
