Beth Pinchas is a purported charitable organization, known as a gemach, within the Orthodox Jewish community, ostensibly dedicated to providing donations to needy individuals. It was one of several charities controlled or accessed by Rabbi Mordchai Fish during the FBI's Operation Bid Rig investigation. Between 2008 and 2009, Fish directed FBI cooperating witness Solomon Dwek to make checks payable to Beth Pinchas and other gemachs to conceal the source of approximately $900,000 in funds believed to be from unlawful activities, such as bank fraud and counterfeit goods sales. Fish and his associates laundered the money by depositing the checks into charity accounts and returning cash minus a 10 percent fee. Although Beth Pinchas itself was not indicted, it was used for laundering and its involvement highlighted vulnerabilities in informal charitable networks. The organization was part of a broader conspiracy involving multiple rabbis and charities in Brooklyn, with funds laundered through an underground network. Post-investigation, there is limited public information on its operations or status as of 2026. No further details on founding, dissolution, or current activities are available from public records.
