Williamsburg’s coolest teenager, Neighbors Allied for Good Growth, celebrated its 16th birthday at Causey Gallery on Wythe Avenue last Saturday night with some of its best friends including a smorgasbord of neighborhood heroes.

Developers Martin Dunn and Rich Mazur, former Community Board 1 member Teresa Toro, and Brooklyn Brewery founder Steve Hindy were among those honored for promoting open space and affordable housing.

The group began in 1994 as Neighbors Against Garbage, crawling across the waterfront of Williamsburg and Greenpoint in search of trash piles, before joining the efforts to protest the closure of a beloved firehouse and fighting luxury development on the waterfront (those were the rebellious teenage years).

Now the organization commands the respect — and support — of all the local public officials, some of whom attended the party, which pulled in $36,000.

Not bad for a teenager.
