The Tree Care Industry Association (TCIA) is a trade association of 2,300 tree care firms and affiliated companies worldwide and was established in 1938 as the National Arborist Association.
Our mission is to advance tree care businesses. TCIA develops safety and education programs, standards of tree care practice and management information for tree and landscape firms around the world. We provide continuing education, training, conferences and publications to promote the safe and appropriate practice of tree care.
