Whole Tree Care

Whole Tree Care

Arboriculture is the art and science of tree care. It looks at the internal processes of trees and how they should be cared for accordingly. Modern arboriculture is about new and better ways to help trees stay healthy, safe and attractive. We provide an eco-friendly, artistic approach to expert tree care combining art, education and conservation using cutting edge tools and technology. We use our forestry and horticulture backgrounds to provide our customers with personalized care of their trees. Our holistic approach considers the life of the tree from the correct choice planting, the health and structure of the tree, to the sustainable use of wood products. All of our work is performed by Certified Arborists in accordance with industry standard (ANSI A-300) tree pruning guidelines.

I fell in love with trees and forests growing up in Colorado and playing in the mountains. I moved to Portland in 2011 and have been working with Jason at Madrone Modern Arboriculture since 2013. I obtained an AAS in Natural Resource Tech from Mount Hood Community College in 2014 and my ISA certification in 2015. I continue to study trees daily because, quite frankly, it's what I love!! I live in NE Portland with my wife and two kids. We keep a large fruit and vegetable garden and smiles on our faces. It's always been my dream to work for a company who's goal is to keep trees where they are and make sure that those that do come down are treated with respect.

I'm an outdoorsman. I'm glad to work in a field where the technical knowledge I gained in school and the outdoor skills I developed as an Eagle Scout are called upon every day. I enjoy the challenges and rewards of keeping the trees of Portland safe and healthy, making your yard look awesome, and getting the most out of every log. When I'm not working you can find me: camping with my wife and my dog, watching for birds, hunting for ducks, cooking for friends and preparing our new home for baby.
