Chaisson has served as the exec director of the nonprofit since 2012. During her tenure, the fest expanded from 5 to 11 days, adding new awards and honors and became a stop for awards season hopefuls.

Randy Mastro, HamptonsFilm board chair, will appoint subcommittee to find new executive director.

The selection will come after this year’s Hamptons Film Festival, running October 4 to 14.

“I’m so proud of work we’ve done, transforming HamptonsFilm from a single annual event into a vibrant year-round non-profit organization,” said Chaisson. “My tenure at HamptonsFilm has been one of the most fulfilling of my career, and the challenge to grow a non-profit in such extraordinary times is something I will forever be thankful to have taken part. I feel I have accomplished what I set out to do, and I am ready for the next chapter.”
