Celebrating Fr. Marc’s 20th Anniversary in the Priesthood!

St. Cassian School and Church celebrate Father Marc Vicari’s 20th anniversary as a priest with this video tribute. Fr. Marc Vicari has been the Pastor of St. Cassian Church in Upper Montclair since February 2011.

Housing Families in Transition (Homeless)

The Interfaith Hospitality Network (IHN) helps families who are homeless by giving them shelter and three meals a day through the hospitality of different churches and synagogues.

St. Cassian Church will be hosting the families during the week of February 18 through February 25.  The parish community has worked together for many years to make this outreach a success.  If you are interested in volunteering and supporting our host week, please sign up using the link below.

Fathers Who Cook Fundraiser

Fr. Marc would like to thank all our chefs who attended our January Fundraiser.  The food was delicious and our venue was filled with great smells and happy laughter from our parish family!  All leftovers were gratefully received at the Montclair Emergency Services for the Homeless.
