Caleb O'Brien, Owner TreeMendus Arbor Care

I’ve spent the last 26 years working with trees, starting on the other side of the world and eventually landing right here in Northern Utah with my own company.

My background started in Australia, where I spent over a decade in the green industry. I did land clearing, bushfire hazard reduction, broad acre slashing, and noxious weed mitigation before moving into roadside maintenance for the Roads and Traffic Authority around Sydney, including the stretches near the Harbour Bridge and Sydney Airport. That work led me into transmission line clearing, which is where I first learned to climb.

When I moved to Utah I spent seven years with a residential tree company, then five more as operations manager for a full service tree company in Park City. Eventually I went out on my own.

Today TreeMendus is run by me. I’m an ISA Certified Arborist and a Tree Risk Assessment Qualified arborist, and I’m currently working toward my Board Certified Master Arborist credential, the highest level of certification the International Society of Arboriculture offers.

Our philosophy hasn’t changed. The tree comes first. That means I diagnose the actual problem instead of just treating what’s visible on the surface, and I take the time to walk you through what’s really going on with your tree before I ever recommend a treatment. There’s no quick fix scam or fertilizer gimmick here. Just an honest look at what your tree needs and a plan built around it.

When you call, you’re going to get me on the phone or a call back from me directly.

Your trees took years to grow into what they are today. They deserve someone who treats them that way.

Give us a call to learn more or to schedule a consultation.
