St George Greek Orthodox Church
The Greek Orthodox Community in Lynn, Massachusetts was incorporated on April 5th 1905. Over one hundred years ago, in the city of Lynn, a pioneering group of Greek people established this church for the purpose of perpetuating their religious and cultural heritage. Since then, the St. George Community has grown into one of the largest religious congregations not only in Lynn, but also in the Greek Archdiocese of America. As a group, the Greek people of Lynn have contributed immensely to the general growth and development of the city in all aspects. Our presiding priest is Rev. Fr. Alexander J. Orphanos
