About us

J Greenstein & Company, Inc., was founded by antique Judaica expert Jonathan Greenstein. For over 30 years, since the age of 14, Jonathan has been the “go to guy” when it comes to authenticating antique Judaica. The gallery holds Judaica auctions every 6 weeks and has collectors, museums and other institutions that purchase these ritual objects to build their collections of Jewish art.

The gallery’s director, Abe Kugielsky is a second generation dealer of antique judaica and is the face and voice of the gallery, running it’s operations day to day.

We also represent new and emerging artists in mediums of both paint and silver, often hosting events at our Cedarhurst gallery.
