What makes the SDA New York Chapter different?

The New York Chapter of SDA was established in 1985 and is the largest chapter in the SDA national organization. With 60 members, our firms are comprised of the leading AEC firms in New York City. SDA members are the core of the systems and processes of these AEC firms – the professionals who ensure the business success of their firms.

Manhattan’s geographic density means that almost all of our member firms are located in Manhattan, or easily reached by mass transportation, so that we are easily able to connect in person for events.

Most of our educational events are hybrid, which creates flexibility for our members. Many of our programs are also available virtually to SDA members across the country, which enhances our knowledge sharing.
