Does anyone know how to contact the gabbaim of the Novominsker Rebbe, the Skulener Rebbe,or the Karlsburger Rov. I would like to go to them for a brocha but I don’t know how. Any help would be greatly appreciated. If there are any other gedolim in the Brooklyn area that you think I should go to for a brocha please tell me how to contact them.
You don’t need an appointment, generally. You could show up to their beis medrash and wait to see them. You just need to find out when they’re around. A good time, often, is to daven Mincha with them and speak to them afterwards.
