Park Avenue Synagogue, located on the Upper East Side of Manhattan, is one of the largest and most influential Conservative synagogues in the U.S. Although the synagogue was originally founded in 1882, the main sanctuary was dedicated in 1927, in a grand Moorish-style, designed by Walter Schneider. The building was subsequently extended in the 1950s and 1980. Since July 2008, the synagogue community has been led by Rabbi Dr Elliot J Cosgrove who was joined in 2009, by Senior Cantor Azi Schwartz . Both the building and the community has grown substantially since then.
