Holy Trinity Cathedral has a small group of praying moms who meet once a week to pray for all of the children connected with this parish family.  Moms, grandmas, aunts, and others who care about children are welcome to join us. Please contact Karen Sobiechowski at 622-4524 or for further information.


Each week, after mass the youth of our church have Sunday School.  We delve into the Gospel so that students understand the meaning of the Gospel.  Activities relating to the Gospel and the time of year are also completed during this hour class. Students partake in community service by completing different activities.   For example, we collect items for the Operation Christmas Child.

membership and outreach team

Our mission is to increase attendance and membership to Holy Trinity Cathedral by fostering a welcoming and respectful environment, where individuals and families can explore and achieve spiritual fulfillment.

The Frederick Chopin Choir

The primary mission of the Frederick Chopin Choir is to enhance the liturgy of the church with beautiful music, both traditional and contemporary, in the Polish and English languages. Always striving for excellence, this small but dedicated group, under the direction of organist Tom Grzywacz, sings in four-part harmony for every Sunday Mass and for special services all year long. Members participate in Interfaith events in Manchester and in concerts and liturgies throughout New England. 


Members support the work of Holy Trinity Cathedral, reach out to the homebound members and nursing home residents, and enjoy outings to various community events. For further information, call 622-4524.
