Regional Chapters
NASTT has a network of nine regional chapters throughout the United States and Canada. Regional chapters offer valuable educational and networking opportunities in your local area. Share your ideas, network with colleagues and find solutions to your everyday challenges. With a single NASTT membership, you're automatically enrolled, not only in the national organization but also in your regional chapter, if one is established.
