An LGBT Chamber of Commerce has been established on Long Island. “Advocating for social justice and the safe workplace is part of that fight. That’s a marathon, not a sprint,” said David Kilmnick, LGBT Network president and CEO. “It will bring more visibility to gay businesses. I think it will also provide networking opportunities for us to get to know each other and support each other,” said Kenneth Letavish Brigandi, owner of Rejuvenna Spa in Sayville.
