I don’t think there’s a Vaad harabbonim any more, I know that many years ago when Rabbi Goldberg took over the Vaad Kashrus of Flatbush he did a total overhaul and cleaned up the whole operation and Turned it into one of the most strict hashguchas, i hear he runs a very tight ship. Agree with Fran that I also was told it’s a very reliable hechsher and there’s a lot of worrisome stuff I heard aboutsome of the other “big” hashguchas who people think are also among the “good ones” but really aren’t.
