The Parish of St Catherine of Siena is a warm and welcoming community of faith for everyone – both for our longtime parishioners, as well as our visitors and newcomers.  We invite everyone into a living and saving friendship with the Lord Jesus Christ, in the communion of His One, Holy, Catholic and Apostolic Church.
We warmly welcome anyone who is new to our area, anyone who is searching for the truth, or anyone who is looking for a spiritual home. We are joyfully and faithfully Roman Catholic in belief and practice - a community of faith, worship, service, and formation.

The Parish Office would be happy to help you with registration information, or to answer any questions.  Give us a call (203-377-3133) or just stop by.  Our office hours, and a listing of our parish staff can be found in the helpful links below. Also, feel free to contact me personally, either at the Parish Office, or stop me after Mass to say hello.
And, once again, welcome!
God bless you!
