Mark was lucky enough to be brought to Haines as a child and has made it his home ever since. An early interest in natural history led him to pursue studies in aquatic ecology, and a love of the sea led to a career as a commercial salmon and halibut fisherman. As well as fishing, Mark pursed an interest in habitat restoration and natural enhancement, working as a consultant and for the State of Alaska to design and oversee the construction of many restoration projects in southeast Alaska. He worked as a senior fisheries biologist for Inter-Fluve, a river restoration consulting firm, researching and designing projects throughout the U.S. He spearheaded the founding of the Takshanuk Watershed Council in 2002, serving as the coordinator during the initial formation of the Council. Mark is now retired from the Alaska Department of Fish and Game, having ending his working career as Manager of the commercial fisheries in Haines.
