Meet Timothy Slape, a certified arborist with tree risk assessment qualifications and a strong ecological awareness. Tim has over 20 years of experience leading outdoor programs and construction projects. After receiving a masters degree in mass communications, Tim’s path to becoming a certified tree whisperer began once he traded in the newsrooms and classrooms for the great outdoors. Tim has professional arborist experience in the Washington D.C., Northern Virginia, and Maryland area, Missouri, Connecticut,  Massachusetts, and North Carolina. As the former Course Operations Manager at one of the first Swiss style Adventure Parks in the country and the Activities Installation and Maintenance Manager at the U.S. National Whitewater Center, Tim has the experience, knowledge, and passion to help you with your next arboriculture or ropes course project.
