Welcome to ISA Michigan (formerly ASM)

The Arboriculture Society of Michigan (ASM) has begun transitioning to our new name, ISA Michigan. We are a non-profit organization founded in 2006 under the idea to promote arboriculture in the state of Michigan.  Its members include arborists, urban foresters, municipal and utility foresters, professional tree workers/climbers, academia and others interested in all aspects of arboriculture and the health and care of Michigan trees.
