Commercial Industrial Broker Society of Long Island

CIBS was formed in 1993 out of the shared belief among the region’s leading brokers that the region needed a unified voice to advocate on behalf of professionalism, ethics and industry cohesion.  Since its formation, CIBS has helped upgrade the industry by offering hundreds of educational programs, seminars, and presentations; advocated professional standards and offered grievance resolution; provided informal mentoring relationships; raised tens of thousands of dollars for local charities; and created social settings in which colleagues have become friends, and competitors respected peers.
