The Gay and Lesbian Community Center of Southern Nevada, known to most simply as The Center, is a nonprofit organization located in Las Vegas, Nevada, that has served the local lesbian, gay, bisexual, transgender and queer community since 1993. The splendid building and the land on which it sits were accomplished following a very generous bequest by Las Vegas educator and businessman Robert L. Forbuss. The idea and scope of the project was suggested to Forbuss by his two closest friends, Las Vegas physicians Jerry L. Cade and Dennis M. Causey.

Jon Sparer is an architect in Las Vegas, Nevada who has worked on numerous hotels and casinos. He moved to Las Vegas in July 1981 and worked for the architecture firm Rissman and Rissman before joining Marnell Corrao. After briefly retiring in 1999, Sparer opened his own architecture firm and was contacted by Congregation Ner Tamid (of which he was a casual member) to design their new temple in Green Valley. Jon was married to another successful architect, John Klai. Both were very instrumental in the opening of The Center.
