Our Team

In order to satisfy the needs of our clients while maintaining the health of their trees, careful selection of employees is of the utmost importance. All employees are hired for character, aptitude, and attitude. They are consistently being provided with opportunities to increase their knowledge of arboriculture, safety, tree care techniques and skills as a part of their continuing education. They are trained and educated as to the proper care of trees in the landscape. Several are certified by the Western Chapter of the International Society of Arboriculture as Certified Tree Workers. Additionally, all of our crew members receive annual aerial rescue training, and are kept current on CPR and First Aid Certification.
