Breyden has completed his Arborist Program at Fleming College and has now been in the industry for four years, starting at the age of 17. Breyden is incredibly motivated and passionate when it comes to being the best climber he can be. Breyden has progressed incredibly over the last year, finding his flow in the canopy and becoming very confident in all aspects of climbing. Breyden has also started doing crane assisted removals, taking his game to new heights

Brayden Hurst

Everybody meet Brayden Hurst. With aspirations of becoming a competent arborist, Brayden is looking forward to completing his arborist apprenticeship at Humber College. An incredibly driven individual who is constantly learning and improving. Brayden has 3 years of experience in the tree care industry and is becoming quite the force out there! Another one to keep an eye on as he grows as a climber.

Lloyd Johnston

Papa Lloyd! My father. Lloyd brings 45 years of small business knowledge.

Meet Troy! Troy has been climbing for two years now and has been in the industry for three years. Troy has truly gone to new heights and has elevated his game over the past year. There is no tree Troy won’t climb and he is always looking for that next challenge. Troy has joined the family business with aspirations to take GLTE to the next level. Troy is becoming an incredible climbing arborist, who is even doing crane assisted removals now!”

Mike Bowes

Mike has been working in the tree industry for five years now. With an unmatched work ethic, Mike is undoubtably as hard working as it comes. In 2019 we purchased two skid steers, a John Deere 317G and a Mike Bowes. His work ethic shows on every job-site, as Mike only has one gear and that’s giving our team his 110%. Not only is Mike a one of a kind employee and person, his willingness to learn and continuously grow as a tree worker is what will make him a force in this industry. Keep an eye on this guy, as I have no doubt he will become a top notch Arborist.

Devon Neal

I would like to give a warm welcome to GLTE’s newest employee Devon Neal. Devon is One of the hardest working individuals, who is yet again, a perfect fit to the team. Devs work ethic is unmatched. His positive energy is contagious. Having no experience in an industry like this, Dev shows no fear for the unknown. I can’t wait to see what the future holds for Dev at Great Lakes Tree Experts.

Mike VanZyverden

Everyone meet Mike! Welder turned tree worker. Mike has such a wide array of knowledge with almost anything and has the most consistent work ethic and pace. From the time we step foot out of the work trucks, to the time we get back to the lot at the end of the day, Mike is nonstop. We look forward to seeing Mikes growth as a tree worker.

Richard Bullivant

Everyone meet Rich! Rich has 7 years of experience in the tree industry and is our newest Estimator. He brings plenty of tree knowledge and carries the same attitude and energy as the GLTE team. Rich is our first point of contact with all customers and sets the tone for the GLTE experience. A major asset to the team!

Alex Ryan

Meet Alex! The newest addition to the GLTE team. Alex is finishing up his second year at Humber College, attending the Arborist Apprenticeship Program. Alex is another example of raw talent. With a willingness to climb everything and anything, I have no doubt that Alex will excel here at GLTE.

With a willingness for continued education, Payton will grow into an amazing arborist.

Marshall Smith

Everyone meet Marshall. Marshall is an electrician journeyman turned arborist. Marshall is an incredibly well rounded and fast learning individual.
