Yes, typically they do. It will commence around 7 PM. The reason I say "around 7 PM", because many congregations in the DC Metro area begin @ 7:30 PM in consideration of the heavy traffic flow in the area. To be on the safe side, I would try to show up at 7 PM. Hope it helps. Also, no one may have answered the phone because there is likely no office attendant there full-time.
I did no one answered
Call to be sure.
