Your Instructor
Mark J. Chisholm is a third generation arborist who works alongside his father Steve, mother Laura and brother Stephen, for the family business the Aspen Tree Expert Co., Inc. Mark has been climbing trees since around the age of twelve and admits that it is still his passion today.

Speaking on such topics as advanced climbing and rigging techniques, crane removals, E.H.A.P, aerial rescue, cabling and bracing, competitive climbing, proper pruning and worker motivation, tree care companies and organizations alike enjoy the refreshing approach Mark takes to education. He is a repeat demonstrator at such tradeshows as TCI Expo and ISA Expo as well as lecturing at Rutgers University, Cornell University and Hofstra University. One of his most satisfying duties is to perform on the job training for professionals around the globe. Mark is also involved with special projects including scouting with the USDA for the Asian long-horned beetle throughout the North East and measuring the tallest trees in his area for the CAA. Another avenue taken by Mark is that of a published author, with articles appearing in both "Tree Care Industry" and "Arborist News."

Chisholm has won the International Society of Arboriculture (ISA) New Jersey Chapter Tree Climbing Championship 21 of the last 22 years and won the ISA International Tree Climbing Championship in 1997, 2001 and, again, in 2010. Chisholm currently holds the world record in the 50-foot secured footlock climbing event, with a time of 13.8 seconds.
