About Us

Think Trees New Mexico is a 501(c)3 non-profit organization dedicated to promoting the education, training, and appreciation of trees, arboriculture, and horticulture throughout New Mexico. Think Trees New Mexico provides training to professionals in the Green Industry of New Mexico and surrounding regions, by hosting an annual conference in Albuquerque, NM. We have hosted this conference since 1986 with an all-volunteer board of committed tree industry members and supporters.

The Think Trees Board is elected by the board of directors. The executive board is the president, vice-president, recording secretary, treasurer, and past-president. The board of directors supports the mission of our organization.

A separate category of our supporters is the “Friends of Think Trees.” These are active volunteers who share in the ongoing efforts to organize and present our annual conference.

Think Trees New Mexico strives to provide our audience with up-to-date accurate, relevant information on trees and their care by bringing nationally recognized speakers and local experts to our conference, We believe in the value of trees, not just as amenities to the human landscape but as living elements in their own right.

Our conference provides Continuing Education Units for both ISA-Certified Arborists and for the New Mexico Department of Agriculture (NMDA) licensed pesticide applicators. You can take the International Society of Arboriculture (ISA) certification exam at Think Trees New Mexico. Registration for ISA exams is through the ISA’s website.

Thank you, everyone, that attend our monthly meetings to organize and present the conference. Since 1986 our success continues to depend on these volunteers and includes everyone that attends and supports the annual Think Trees Conference.

At Think Trees New Mexico, we do think about trees. We believe in the value and beauty of trees.
Be a part of the future – plant and care for trees today!!
