Since then, the company has grown exponentially from a couple friends working weekends with a single boom truck and trailer, to an ever-expanding company, currently with 12 full time employees and industry leading equipment including a spider lift, grapple truck and 40-ton crane. Mike’s vision for CM Tree Service has been growth from the start. His biggest goal is to be a good steward in the community and form partnerships that reach beyond what one company can do alone. He prides himself in providing careers for local families, giving donations and helping complete projects for local organizations that impact our community and keeping Billings trees healthy and beautiful for decades to come. Mike serves on the board of AMTOPP (Association of Montana Turf, Ornamental, and Pest Professionals), the BBWA board and has been recognized as a 40 Under 40 recipient. CM is active in many other organizations in the community including CLDI, Saluting Branches, LaVie, Ramsey Keller Memorial, Spring into Sight and many others. These partnerships are what make CM a great company to be a part of.

Their family keeps busy working their land and raising goats and chickens.  If Zach could meet anyone living or dead, he would want to meet his younger self so he could tell him to invest in Bitcoin when he had the chance.

Jaiden Gray – Cutter / Maintenance Foreman

JaidenJaiden moved to Montana in 2023 and joined the CM Tree Service team. He is one of the younger members of our team and brought a work ethic that most men his age haven’t even thought about. Even though Jaiden has only been in the industry a short time, he already has set some amazing goals of getting certified to operate the crane and become a certified arborist. Personally, he looks forward to owning his own land and building a shop and home here in Montana.

When Jaiden is not working in the trees, on equipment or controlling the local racoon population, he enjoys hunting, fishing, boating, riding dirt bikes and camping with his 2 dogs. Being originally from Shoshone Idaho, the outdoors are in his blood. If Jaiden could meet anyone living or dead, it would be Johnny Cash so he could hear him sing live. We look forward to helping Jaiden grow within our company and personally through the years and we are blessed to have him as part of our team.
