Javier Quiroz 

​Javier Quiroz, at 17 yrs of age, started his journey at the San Diego Safari Park as a horticulturist for the first 3 years, quickly realizing his passion for trees; Javier began studying, learning and climbing which led him to becoming the Lead Arborist at the San Diego Safari Park for the last 35 yrs. Javier's role as Lead Arborist at the Park is to oversee all the tree work, teach new techniques along with safety training throughout the department. 

Javier's credentials include : Certified Arborist, Certified Tree Worker, Certified CTSP, Certified Industrial Tower Climbing and Rescue, CPR-First Aid Instructor. He's also been involved in several projects including British Columbia, constructing zip lines and canopy tree walks for the University along with constructing the zip line at the Safari Park.

Javier has been active with Hispanic tree workers, eagerly passing on everything he's learning with both the science and field skills that are necessary for an Arborist. He's an avid splicer and owns his small business specializing in all phases of tree work. 

One of the most important goals for me is to see that climbers are able to integrate safe, modern skills into their daily work. With all of the new tools and techniques, I believe that climbers can last longer, safely in this industry that we love and call " TREE WORK "
