Those who knew Dennis will remember his big heart and his creativity. He had a gift for choosing the most beautiful, heartfelt cards that brought tears to your eyes and reminded others how much they mattered. He enjoyed camping, fishing, gardening, and spending time outdoors. He had a deep love for the animals that shared his life. An artist at heart, Dennis was endlessly creative, a dreamer and a tinkerer who was happiest when his hands were busy bringing an idea to life. He loved to grill and found joy in the simple moments spent with family.
