We are heartbroken to share the passing of our friend and colleague, Rob Tangeman, after a courageous battle with cancer. Rob was a valued member of the Garmann Miller team and a steady, caring presence to those who had the privilege of working alongside him. He was a devoted husband, father, and friend. We will miss Rob greatly, and our thoughts are with his family and everyone who knew and loved him.
