Tree Climbing  


Owned and operated by Austin DeRock


Born and raised, in Truckee, California, I have always had a passion for the outdoors. Believe it or not, my grandmother got me interested in rock climbing. As a teen, she encouraged me to take courses through Alpine Skills International. Climbing trees has been a part of my life ever since.


  • At age 18: I joined the California Conservation Corps which led to an internship with the California Department of Transportation tree crew. The internship lasted three years, and enabled me to earn the state Qualified Tree Worker certification

  • From 96-’98: I worked  for U.S Army Corps of Engineers, as a maintenence worker for Englebright Lake and Martis Dam sites.

  • From 1998-2004: After receiving my Line Clearance Tree Worker Certification, I worked as supervisor for PG&E and other subcontractors. 

  • In 2007: I participated with Steve Stillett and crew in the health/hazard evaluation of the 
    Robert E. Lee Tree in King’s Canyon.  

  • From 2008-2009: I participated in annual Tree Week and completed the Facilitator Course through Tree Climbing Northwest, sponsored by Tree Climbing Planet. The course was taught by Tim Kovar.

  • In 2009: I was assigned the role of Lead Climber on a canopy research project with the Department of Agriculture in Calaveras Big Trees State Park. My responsibilities included fully rigging four Giant Sequoias, assisting the researchers in ascending into the canopies, and facilitating the installation of insect traps.


I have been a Certified Arborist for nearly 10 years, and I have been running my own tree business in Nevada County since 2004. I regularly continue my educution by pariticpating in seminars and conferences when ever possible.

New Leaf Tree Climbing is my lastest venture in the trees. New Leaf Tree Climbing offers a variety of opportunities to learn about trees and climbing. All techniques taught meet all requirements established by the American National Standards Institute (ANSI) for tree care operation. One-on-one and small group instruction is available for learning the skills for working in trees with minimal impact. 


Workshops can include any of the following:

  • Discussion of safety equipement and safe climbing practices

  • Techniques for rigging a tree

  • Learning to climb as a team

  • Learn essential knots needed for climbing

  • Learn safe methods to comminicate with others while in the trees

  • Participate in fun activites in and around the trees

  • Ascend using ropes and climbing gear

  • Descending using self-belay technique

  • Traverse between trees 

  • Relax in a Treeboat high in the canopy

  • Even, sleep in a tree!

  • Aerial Rescue
