Tom Hanson has extensive experience as a consulting forester and consulting arborist. His interest in trees and forests is rooted in his rural northwest Washington upbringing.  He graduated from the University of Washington with a degree in Forest Management and immediately joined Seattle-based International Forestry Consultants, Inc. (INFO) as a field forester cruising timber throughout the western United States.  This experience formed a sound basis for his transition to forest appraisals, forest land management, and urban tree assessments and urban forest assessments. He eventually acquired INFO and developed it into a full service consulting company of professional foresters and arborists with diverse expertise. Fifteen years later he merged INFO into American Forest Management Inc. and remained with them for 5 more years. In 2016 Tom formed ArborInfo LLC in order to provide a more personal approach to arboriculture and forestry.
