The Preservation Trades Network (PTN) is a 501(c)3 non-profit membership organization founded to provide education, networking and outreach for the traditional building trades. PTN was established on the principle that conservation of the built environment is fundamentally dependent on the work of skilled people in all of the traditional building trades who preserve, maintain and restore historic buildings, and build architectural heritage for the future.

The International Preservation Trades Workshop is the only annual event in North American which brings the foremost practitioners of the traditional trades together in a single venue dedicated to sharing the skills and knowledge of all of the trades employed in conservation of the built environment.
