Gregory V. Wolterstorff, P.E.


Vice President
Director of Natural Resources

A Bit About Me

I love fly fishing: Trout, steelhead and salmon in the rivers and streams around the Great Lakes; snook and redfish in the Florida flats and surf; bass and sunfish in various Michigan lakes. I also enjoy planning outdoor adventures with my kids and friends: camping, hiking, paddling, rustic cabins and rugged mountains. Many around town see me on the fields and courts through my soccer and basketball coaching in various leagues. I am father of six. And a seven-year veteran of backyard ice rink construction – bring on the cold!
