In July 1911, a charter was drawn up for the formation of an Orthodox synagogue named Congregation Agudath Achim Anshai.

[1][2] Raphael Riemer, who immigrated to Freehold from Russia in 1906, was the synagogue’s first rabbi and cantor.

[14] In April 2003, the synagogue named its chapel the Oglensky Chapel, after David Oglensky, a synagogue member and soldier who had been a lieutenant and commander in the 740th Tank Battalion of the U.S. First Army killed in the Battle of the Bulge, who for his gallantry was awarded posthumously the Purple Heart and the Silver Star.

[2][5] Past president Jerry Einhorn said: “I think it’s absolutely wonderful we have reached our 100th year.

[2] As of 2016 the congregation's Rabbi is Ira Samuel Grussgott, the Cantor is Aron Heller, the Executive Director is Marvin Krakower and the President is Jesse Glick.

[16] Ground was broken in 1947 for a new synagogue, on lots measuring 175 by 250 feet (53 by 76 m) that were purchased in 1943 and 1945, responding to the need for a larger facility.

[3][7] The synagogue was dedicated on August 25, 1957, with Governor Robert B. Meyner and his wife as guests of honor.

[2] The building also houses 12 classrooms, social halls, a 350-person formal ballroom, a youth lounge, a library, a smaller chapel, and kosher kitchens.
