Formed in 1912, the choir joins the priest, deacons, and altar servers in celebrating the Divine Liturgy every Sunday morning by singing the beautiful hymns of the Divine Liturgy.

Open to all women and men, the choir attracts both novice and professional singers. Since 2013, the youth choir has given the children of the parish the opportunity to learn Armenian hymns and participate periodically in Divine Liturgy.  For further information, please contact Dn. Gregory Krikorian, Chairman,

Erevan Choral Society

Erevan Choral Society of Greater Boston was founded in 1966 by late Father Oshagan Minassian, a gifted musician and an exceptional human being, who for his love of Armenian music and culture brought together a remarkable choral group with gifted and versatile singers and musicians from all over the Greater Boston communities. The chorus is also complemented by a professional 23-member orchestra.  Since the inception of the first concert, performed on June 4, 1967, over 50 years Erevan Chorus has performed throughout New England, New York, New Jersey, and California to the capacity crowds.  The annual Christmas Holiday Concert has become a much-loved traditional event in New England, which attracts crowds not only from Greater Boston Area, but also from all over New England.  


After passing of Hayr Oshagan in 2008, since 2009 Composer, pianist and conductor Konstantin Petrossian has served Music Director and Conductor of the Chorale. In collaboration with Armenian Composers for many years, the chorus has refreshed its repertoire with several varied, engaging and delightful musical collections that deeply connect the audience with performers.  Many works of Armenian Composers have been premiered in Boston and performed by the Chorus.  As a matter of fact, Erevan Chorale is the only chorus of its kind performing outside Armenia, which made a name for itself not only in U.S. but also in the world. 

Recently, in recognition of the outstanding work that the Chorus is carrying out to promote Armenian music in Diaspora, Erevan Chorale and Orchestra was awarded the Yerevan City Gold Medal by the order of Yerevan City Mayor Hayk Marutyan.

1000 Club

Through the use of a cash lottery available to only a limited 1000 members, the organization’s goal is to raise additional funds to help meet the general obligations for the church. Each membership is $60 per year. The member has the ability to win one of twelve cash prizes ranging from $50 to $1000 at each monthly drawing. The drawing is held on the last Thursday of each month. Two drawings per year feature a dinner social event. 

A membership in the 1000 Club also makes a great gift for any occasion – especially Christmas, graduations, Mother’s and Father’s Day, birthdays, anniversaries, or any other special occasion.  It’s also a wonderful way to thank your loyal customers if you own a business or any business where you have repeat clients.  It starts with a gift card sent to the recipient advising them of your special thoughtfulness.
