George was the definition of a simple man. An electrician by trade, he owned and operated Tri-Marine in Wonder Lake. He worked hard, fixed things when they broke, earned respect, believed in building things with his hands, and loved his family unconditionally. George’s favorite times were spent on the waters of Wonder Lake, sailing, fishing, driving his pontoon boat, and windsurfing. His art took form in his woodworking shop where all of his grandchildren can remember helping stain or sand his creations. He led and lived a beautifully simple life focused on family.
