Alex Julius

The Davey Tree Expert Company

I’ve always appreciated the presence SCA has in the industry, both in a support function and as an industry leader in education and engagement. In my six years working at ISA, I watched SCA members participate at ISA Conferences, organize RakeMaster, serve actively on the ANSI Z133 committee, and organize workshops. This presence does not go unnoticed, as not only does it help improve the quality of our workforce, it also improves our engagement as an industry.


I’ve spent my career serving this industry through educational development and engagement, as well. Following a Master’s program, I worked for West Coast Arborists on tree crew. I realized quickly that I wanted to have a more global impact and took a position at ISA Headquarters. At this point, I was already competing and volunteering at tree climbing championships, and presenting at conferences on safety. During my time at ISA, I served as secretariat to ANSI Z133, worked on TRAQ development and revisions, and online learning, in addition to many other competition-related functions. I’ve recently started at The Davey Tree Expert Company, serving as the Employee Development and Safety Training Specialist, once again, putting myself in the position of supporting employee education, which is where my passion has always been.


I know my broad mix of experience and interests would complement SCA well, as it continues to not only educate arborists, but engage new and existing members.
