Marsh's love of dogs began at an early age. He spent his life as a professional handler, training and showing dogs across the United States. Marsh was a great friend and mentor to those who shared his passion for dogs. When not in show ring, Marsh worked for The Whole Earth Provision Company. He was an avid outdoorsman favoring fly fishing and hunting. Marsh attended the St. Mark's School in Dallas, Tx. He was preceded in death by his parents Marshall and Fran Comerer, Dallas. He is survived by his sister Mary and husband Mike Bevel of Carrollton. His nephews Cliff Bevel and wife Jennifer; Shane Bevel and wife Fran; Cody Bevel and niece Becky and husband Jared Hornback. In addition, he is survived by his loving companion Linda Goddard and eight great nieces and nephews.
