About Us                                                                                    


St. Mary School was founded in 1914 by the School Sisters of Notre Dame.  For over one hundred years, the “charism” of that religious community, which is “unity, and educating in all we do and world vision” continues to permeate who we are. 

Hopefully, you will take a few minutes to visit with us online and discover the great opportunities afforded to our students.  We pride ourselves on educating the whole child with a special emphasis on his or her religious formation in the Catholic faith.

You are always welcome to come and see our wonderful school and consider joining our great school family!

The New York State Legislature has returned from their President’s week break and is moving forward in earnest with state budget negotiations.  In addition to considering the tax benefits of the newly expanded 529 plans, lawmakers are also considering whether they can restore the “instructional time” standard in Mandated Services Reimbursement.  If we don’t fight to restore this well-established standard, our schools will see a cut in their much needed reimbursement.


This link, Take Action for Catholic Schools, brings you to the action alert on our website.  I strongly encourage you not only to personally follow-up on the action alert, but to also share this email and link far and wide throughout the Catholic school community.  Together as diocesan staff, school principals, teachers, families and friends, our collective voice is considerable. 

Increased state support for our beloved Catholic schools is indeed possible but only if we all  Take Action for Catholic Schools.

Thank you for doing your part!
