Mark Douglas Mandenberg (October 1, 1952 - June 27, 2017) was a man of many talents who loved life and lived it to the fullest! He worked for Michigan’s Department of Natural Resources for 28 years, turning railways into trail ways that countless nature lovers enjoy year round. An avid outdoorsman, Mark valued the stories of the woods and time spent outdoors hiking, camping, hunting and fishing. Your donation to the Michigan Fitness Foundation will go towards a trail memorial for Mark. Details are still unfolding and you will be informed and invited to visit when the memorial is completed.
