Miami has the largest Dominican-American population outside of the NYC metropolitan area, probably close to 100,000 at the moment. I grew up there too. It used to be that all Dominicans used to live near Allapatah or the Overtown area but alot has changed over the years. A much larger amount of professionals now, working for all those big companies down there. There have to be several professional organizations down there, start by looking at
DANR which has several links. Hopefully I'll be back in the next two years working for one of those companies myself. The Dominicans down there are decidedly more low-key than those from the NYC area, even though most of them came from that area. It also might have something to do with all the rich DR folks buying houses and condos on Brickell Ave for their "North American" business ventures........
