Welcome from our President


Welcome to Mercy High School!  

May these pages introduce you to the special spirit that is Mercy!

When the Diocese of Norwich opened Mercy in 1963 and invited the Sisters of Mercy to staff it, it was to provide a sound Catholic education in the Mercy tradition for young women. 

We, at Mercy, are called in a special way, to carry on this tradition started over 180 years ago in Dublin, Ireland.  When Catherine McAuley founded the Sisters of Mercy, she envisioned as one of her special works, the education of women – women who would competently and compassionately bring the mercy of God to the wounded world.

With the establishment of the Mercy Education System of the Americas (MESA) on July 1, 2017. Mercy Middletown became formally affiliated with many other Mercy schools in witnessing to Mercy and in carrying on Catherine’s vision.

Our young Women of Mercy undoubtedly receive an excellent academic foundation which will prepare them well for whatever they choose to do in life.  I firmly believe that they also receive much more.  They learn to be Women who pray to deepen their relationship with God.  They learn to be Women who show compassion and to reach out to those in need.  They learn to be Women who demonstrate hospitality by welcoming the stranger and the lonely. They learn to be Women who revere the dignity of each individual and who recognize each person’s uniqueness.  They learn to be Women who serve and reach out to this school community and beyond these walls.

Know that you are always welcome!

In Mercy,

Sister Mary A. McCarthy, RSM
