Temple Beth Am was a Jewish Reform congregation founded by Rabbi Mel Hecht in 1984 in Las Vegas, Nevada. In 1992, some members of the congregation, unhappy with Rabbi Hecht's leadership, broke off to form Congregation Adat Ari El. Construction on Beth Am's campus began in Summerlin in 2001. In 2007 Temple Beth Am and Adat Ari El merged to form Temple Sinai.

Midbar Kodesh is a Conservative Jewish temple founded in Henderson, Nevada in 1995 by former members of Temple Beth Sholom. Population growth and physical expansion of real estate warranted the establishment of the second Conservative congregation in Southern Nevada, whose name means “Holy Desert.” Temple Beth Sholom was moving to the west side of the valley, and a group of families- the Kaminskys, Goldmans, Rothmans, Simons, Goldsteins, and Feldmans- decided to start a new temple on the east side.
