Jonathan Greenstein is an antique Judaica authentication expert.[2][3][4] He is the owner, chief expert and president of J. Greenstein & Company, the only auction house dedicated solely to Jewish religious ritual art.[5][6][7][8][9] Greenstein represents rare pieces of antique Judaica and Jewish art.[10] Additionally, he is the founder and president of Mercy Home Care and Medical Supplies, a medical equipment and disposables company located in Brooklyn, New York.[citation needed]

Early life and education[edit]

Greenstein was born and raised in Brooklyn, New York.[11] His parents were Donald and Janice Greenstein. He was raised in the Orthodox Jewish faith. At the age of fourteen, he worked at Gold Bug, an antique store, and began collecting Judaica.[5] Greenstein visited flea markets and garage sales to add to his Judaica collection.[12] Eventually, Greenstein began dealing in antique Jewish ritual objects.[8] He received his bachelor's and master's degree from Brooklyn College in health administration.[11]


Greenstein auctioneered a charity auction in 2002 at the Park East Synagogue in New York City.[5] He organized the pieces and made the catalogue for the auction. Shortly after, Greenstein received an auctioneer's license and hosted his own auction.[5] In 2003, he founded J. Greenstein & Company in Brooklyn, New York.[7] The Judaica retail gallery and auction house focuses on religious art from the 1600s to 1938.[13] J. Greenstein & Company auctions include people on the auction floor, the phone and available via the web.[14] In 2010, Greenstein moved the company's headquarters to Cedarhurst, New York.[7] J. Greenstein & Company has also hosted celebrity Judaica including Sammy Davis Jr.'s personal menorah and items from victims of the Bernard Madoff scandal.[15][16]

By December 2012, 600 people including Michael Steinhardt, a billionaire hedge-fund manager and antiquities collector, received Greenstein's auction catalogs.[17] That year, he hosted "Jewish Gilt," a Jewish antiques television show featured on the Jewish Channel.[18] In December 2014, Greenstein sold a Hanukkah menorah for $100,000 and added a spice box valued at $337,000 to his collection.[2][5] The menorah was made in Ukraine during the 18th century.[10] In 2016, J. Greenstein & Company hosted an auction featuring 232 rare objects including rare Judaica items belonging to Harvard law professor Alan Dershowitz.[19][20][21] Greenstein acquired Zionist leader Ze'ev Jabotinsky's French refugee ID card, and his company auctioned it off in June 2017.[22][23]

Greenstein has been featured on CNN's Situation Room with Wolf Blitzer, NBC News with Chuck Scarborough, The New York Times, MarketWatch and The Huffington Post.[7][10][24][25] Additionally, he is a frequent guest on Fox News.[citation needed]

Personal life[edit]

Greenstein lives in Long Island, New York and has five children. He is married to Sima.[citation needed]
