A division of the American Choral Duirectors Association, serving the states of Connecticut, Delaware, Maine, Maryland/DC, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont.

The regional structure of the ACDA dates back to the first meeting in 1959, but it was not implemented until 1961. At that time, the founding members separated the country into six regions, each electing a “state chairman” or president. A seventh region was added in 1979 to accommodate the ever-expanding membership. Choral composer and arranger Harry Robert Wilson (Teachers College, Columbia University) served as the first president of the Eastern Region. Our first region conference was held in 1961 (in conjunction with MENC).  The first independently organized region conference (Southern Region) was held in 1970.
