I have 45 years of experience, and specialize in the field of wilderness search and rescue with specific knowledge in the areas of managing a search and rescue program, managing a search or rescue incident and training search and rescue and incident command system personnel. I have published on such topics as land search environment, basic search theory for the initial attack incident commander and search area segmentation. I have testified on supervising teenagers in a mountainous environment, emergency response to a missing person in a major United States ski area.
