Be an ISA Patron Sponsor

ISA Patrons

In 2010, ISA launched the ISA Patron program, which replaced the ISA Sustaining Member category. The support of Patrons make it possible for ISA to carry out our mission and invest in initiatives that help to promote the practice of arboriculture on an international scale.

With three levels of support to choose from, the Patron program provides companies with a chance to show their support of other professionals in the industry, as well as, industry and public education initiatives.

Support educational programs

ISA Patron support sustains important programs such as:

  • Leadership Workshop–Training members from around the world to lead our component network.
  • Student Opportunities–Students are the future of the industry
  • Public Outreach–Expanding our reach to the public including

Encourage new professionals

All levels of Patron support include one or more complimentary ISA memberships, allowing you to introduce others to the world of arboriculture, including students. Just let ISA know who you would like to be provided with this benefit when you apply.

Contact to learn more about how you can become involved.

You may also download the Application to learn about detailed benefits of the program.


The Patron Program provides resources that allow ISA to focus on leadership development within your organization’s network, student outreach opportunities, and public education. JOIN OTHER INDUSTRY LEADERS TODAY!
