About Us & Our Mission

Celebrating over 55 years of education!

Located on a beautiful campus in the historic village of Nichols in Trumbull, St. Catherine of Siena (SCSS) has been successfully shaping the lives of young children from preschool through 8th grade for many years. A co-educational school within the Diocese of Bridgeport, we were founded in 1965 under the direction of the first parish pastor, Rev. Edward D. Halloran. Sr. Agnes Mary S.S.N.D., opened the school with 71 students in three classes in the church hall.  By 1968 the school building reached its capacity of 250 students in eight grades. The building was expanded in 1975 to include kindergarten and again in 1987 to make room for preschool. Sr. Anne Marie Dorff S.S.N.D. joined the school in 1978 and was the longest-serving principal until her retirement in 2009. In July 1991, Monsignor Richard J. Shea was named the pastor of the parish until 2015.  Msgr. Shea and Sr. Anne Marie worked together for many years to create a community of faith and academics. 
On March 15, 2015, Father Joseph A. Marcello, an alumnus of SCSS, was installed as the fifth and current Pastor of Saint Catherine of Siena Parish. Mrs. Rachel Ambrosio was hired as the current Principal of St. Catherine of Siena School in August of 2019.



Students grow in their faith daily. Our teachers infuse the ten core Gospel Values in all areas to go above and beyond daily prayer. As followers of Jesus, we strive daily to emulate His love, kindness, and compassion through our thoughts, words, and actions. The student body attends masses on First Friday and Holy Days. Classes take turns participating in the preparation of the Mass each month. There are many opportunities for students to participate in and attend prayer services throughout the year. We are confident in our students' ability to conquer many of the moral challenges encountered along the journey to adulthood.


As a Catholic school, we are here to educate the whole child; mind, body, and spirit. Our well-rounded program includes classes in Spanish, technology, music, art, and physical fitness. In addition to our rigorous academics, our school prides itself on offering a wide variety of extracurricular activities, including athletics, instrumental music, student council, and many other clubs, to help develop leadership skills both in and out of the classroom. Through commitment and discipline, our students become confident, compassionate leaders.
 We are proud to say that our students are accepted into local competitive college preparatory high school programs. These programs include Fairfield College Preparatory School, Our Lady of Mercy Lauralton Hall, St. Joseph High School, Sacred Heart Academy, Notre Dame-Fairfield, Notre Dame-West Haven, Hopkins School, Chase Collegiate School, Trumbull Regional Agricultural and Biotechnology, and more. We are accredited by the New England Association of Schools and Colleges (NEASC) and were named a National Blue Ribbon School of Excellence. 


SCSS is purposefully a small school, fostering close personal connections within the community as a whole. The students, faculty, and families partner in the development of the student.
The faculty is intentional in the ways that they work with children to build a sense of community. Our talented teachers work tirelessly to inspire a lifelong love of learning. They work collaboratively to meet the needs of all students and prepare them for high school and beyond.
Parents play a vital role in the community at SCSS. Teachers and parents partner in the education of the student.  Working at home to reinforce the principles learned during the day is critical to the learning process. Our parent volunteers are involved, supportive, and actively participate in many activities during the school day and beyond. Several current parents are alumni of the school, genuinely making the community a unique family. The hard work and support of many families and staff members over the years have developed and sustained the vibrant school SCSS is today.  
St. Catherine of Siena is truly a school like no other.
