Adhem Theriault, Owner ECO Tree Company Madison, Arborist since 2006

A Message From The Owner

My passion for the urban environment started long before I attended college for urban forestry in 2006. I’ve been a dedicated arborist in the Madison and Dane county area since 2008. Sustainability and preservation of the urban forest have been my main focus since becoming a professional arborist. I had a formal education in Urban Tree Care at Mid-State Technical College. From there, I went on to work and train with several of the best and most respected arborists in Madison, Wisconsin. Through the years I’ve sharpened my focus and specialized in disease diagnosis and treatment.
I am truly dedicated to being a top arborist and continuing my education with the Wisconsin Arborist Association (WAA) and the International Arborist Association because I believe to have the most positive impact, you must constantly seek cutting-edge education and research.
