Prospective Members

Thank you for your interest in membership in ISA’s Rocky Mountain Chapter. You have the option of joining only the Rocky Mountain Chapter for $52, or the full International and Chapter membership for $187. We recommend the full International membership which entitles you to receive the excellent “Journal of Arboriculture” and “Arborist News” (6 issues of each per year) in addition to the Chapter benefits listed below.

The ISA Rocky Mountain Chapter is at the forefront of urban, community, commercial and utility forestry in this area. The chapter has gained recognition from the national society for the quality of its local programs and newsletter, and commitment to tree-related education and research. Specifically, Chapter membership entitles you to:

  • Quarterly issues of “Rocky Mountain Arborist” keeping you up to date on tree industry developments and news unique to our Rocky Mountain region.
  • Top educational programs offered at the annual ProGreen Expo held jointly with other green industry organizations in Colorado. This show takes place in January of each year.
  • Special workshops to fulfill Continuing Education requirements under the ISA Certification Program.
  • The excitement of “hands on” educational activities and tree-climbing competition at the Tree Climbing Championship in June.
  • Keeping up your knowledge and certification at the Pesticide Applicators Workshop in November of each year.
  • Member Discounts to the above, plus any additional new special programs that might be currently in the planning stages.

The majority of our programs take place in the Denver area where most of our members are concentrated. However, we usually participate in at least one program a year in the other three states comprising our chapter.


Please contact the Chapter Office, (720) 977-7941, for an application and membership packet.

After reviewing the Rocky Mountain Chapter membership application and the ISA International combined membership application, if you decide to become a combined International & Chapter member, please send their application to the Champaign, IL address. They will reimburse the chapter for our portion of the membership. If you are joining the Rocky Mountain Chapter only, send our application to the Chapter office address listed at the bottom of our application.

Congratulations on your desire to continue growing as a professional arborist!
