Having earned a Bachelor’s degree in urban forestry (University of Minnesota) and a master’s degree in tree physiology (Iowa State University), Zwack has been instrumental in the development and communication of Rainbow’s protocols for products such as Arbotect, Alamo, and Cambistat.
Over the years he has been at the center of Rainbow’s Quality Assurance programs, and has consistently spoken across the United States before various Green Industry audiences and ISA chapter conferences. Zwack is well know for his effective training programs before national sales groups, regional distributors, and commercial, municipal, and utility practitioners.
Zwack is also known for his industry leadership and participation as reflected by his positions as Vice Chair of the TREE Fund Liaison Committee and recent election to the Board of Directors of the Society of Commercial Arboriculture.
Zwack will be working directly with major accounts across the United States while he continues to support other important roles within the company. He makes his home in Plymouth, Minn.

Thompson, formerly of Rainbow Treecare (the 31-year-old commercial foundation for RTSA) assumed his new role in October 2006.
“It’s been a bit of a transition with traveling the country, but it’s not unfamiliar territory,” he said. “While on the tree care side I really enjoyed my role of developing our consulting arborists and the marketing tools that supported them. In this new position I get to have a similar impact with tree care companies across the country who appreciate our products and the expertise we can bring. Building distribution is something I’ve done in the past.”
Prior to his five years at Rainbow, Thompson held multiple management positions at Novartis Seeds, with years of experience in sales, distribution, marketing, and production.
Rainbow Treecare Scientific Advancements, located in Minneapolis, Minn., is a developer and marketer of tree health care products.
