The Over-the-Rhine Chamber of Commerce represents its members by promoting economic vitality and fostering a socially and culturally diverse Over-the-Rhine community. We accomplish this mission through initiatives around marketing, communications and signature events, business attraction and retention efforts, and safety initiatives. The OTR Chamber was formed in 1985 as a 501(c)(6) organization. It created the OTR Revitalization Corporation, a 501(c)(3), in 2000 to tap into the grants and fiscal gifts available. The organizations work hand in hand to bring resources, events, commerce and awareness to the 360-acre neighborhood.
