Among the many accomplishments of the Erevan Choral Society are annual Spring and Christmas concerts. The chorus has also participated in various music festivals and celebrations, and has also performed throughout New England, New York, Connecticut, and California, receiving consistent praise in both the Armenian and American media.
The chorus presently consists of 50 dedicated and gifted singers complemented by a professional 27-member orchestra. New members are invited to come and join their ranks and share in the joy of singing in the common love and magic of beautiful music performed for the aesthetic growth and cultural enrichment of their audiences and communities.

Father Oshagan Minassian, founder and conductor of the Erevan Choral Society, was also the director of the choir of the Holy Trinity Armenian Church, a position he held from 1965 to his passing in 2008. Father Minassian received his Masters Degree in Religious Education in 1962, his Th.D. in Church History in 1974, and his Masters Degree in Sacred Music in 1982 from Boston University.
