Who we are

Great Lakes Trailbuilders, LLC was started in 2008 to bring a low impact and environmentally friendly approach to trailbuilding and design to the Midwest.  Willie Bittner started working on trails 20 years ago with the Wisconsin DNR and over the years he has worked from coast to coast building trails and teaching the different methods and styles to volunteer groups, conservation corps and state and federal agencies. 

These days Great Lakes Trailbuilders has worked both nationally and internationally, working with all types of user groups.  As owner and lead designer, Willie is dedicated to sharing his experiences, engaging users and developing leading edge trails.  His projects have taken him from designing new National Parks trails in Patagonia to co-founding WisCorps, Inc. a Wisconsin based Conservation Corps to leading trainings on everything from sustainable trail construction to trail psychology and rigging.
