“It is with a heavy heart that we inform you that SigMa must close our doors and vacate our space,” the message said. “We hope this is a temporary measure until COVID is behind us.” Established more than 25 years ago, SigMa has operated as a 501-C7 non-profit, with the mission of ‘education, socialization, networking and providing a safe clean environment for men to explore and practice BDSM, kinks and fetishes.” It was one of the only clubs of its kind in the country.
