Thursday Night Happy Hour

Every Thursday night the Dulles Triangles meet at the Sheraton in Reston (11810 Sunrise Valley Dr.) VA in the Cosmopolitan Lounge on the second floor from 7pm until about 9pm. Ask for any Board member if you are visiting us for the first time. We'll make sure you get the opportunity to meet everyone! There are usually between 20 and 30 people who come to the happy hour each week. You do not need to be a member to attend and it's a great way to meet new friends! Stop by Thursday night and meet us! Typically, there is a group who go out to eat afterward. Please feel free to join in on that as well.


In addition to our weekly Happy Hour, we hold many Group sponsored events throughout the year. These include pool parties, dances, brunch, Halloween and Holiday parties. See below for event dates.

And that's not all, our members also sponsor events throughout each month, so there is always something to do.
