We have two students enrolled and both are enjoying the experience. Class sizes are small and the opportunity to participate in additional activities are plentiful. Our boys have done the school plays, music, art, football, basketball, soccer, lacrosse, debate team and student government not to mention numerous service projects. The academic rigor and workloads can be stressful but are manageable. The emphasis on character development stands out and creates a real bond amongst the boys. The motto to "Love God, Work Hard, and Take Good Care of One Another" is a genuine point of emphasis rooted in Christian values.

St. Sebastian's has been an amazing school for our two boys. They are both receiving a terrific education from incredibly committed teachers while feeling part of wonderful community. They are being taught academics, athletics, hard work and compassion. They are proud to go there, and we are very happy with their experience.

Why St. Sebastian's? Have you heard that it is an incredibly special place? A school with a dynamic, dedicated faculty who deeply care and truly understand boys. They offer a rigorous academic curriculum and also encompass arts and competitive athletics. A high level of student engagement and encouragement to take learning far beyond what is taught in the classroom. An environment that cultivates believing in yourself, to become the best version of yourself, and maturing into men of integrity. A warm, connected community of families. We can attest that all of this and more is true of St. Sebastian's School. We have twin boys currently attending. They have different personalities and their own unique learning styles. We are amazed by the genuine effort, of every faculty member we have come across, and their devotion to the boys' success academically, spiritually and personally. It is also extremely remarkable that during this unprecedented time of distance learning, St. Sebastian's is offering unparalleled, effective, cohesive and creative learning daily surpassing any expectations. The dedication of the entire faculty is rare. We feel extremely fortunate to St. Sebastian's for providing our sons with such an outstanding experience.

We currently have two boys at St. Sebastian's with a third enrolling in the Fall. Without doubt, this school fulfills all our family's hopes and desires for our boys' education as they grow from young boys to mature adults. Although each of our boys is unique with their own set of strength and weaknesses, St. Sebastian's has managed to embrace their differences and help them feel confident as they grow in mind and body. They've gained a belief in themselves and a drive that wouldn't be possible without the love they experience each day from their faculty and coaches. Their willingness to want to achieve and work harder has made us extremely proud. We couldn't be more thankful or feel more fortunate to send our boys to St. Sebastian's.

My husband and I both attended public schools, so we were new to the whole private school world. A friend of ours had attended St. Sebastian's School in the eighties and always talked about what a great experience he had there. That is what brought us to Seb's and we would never look back. Seb's has not only accepted my three boys but has also embraced my daughters and our entire family. My boys are challenged and pushed to be their best, and they know that the faculty and staff always have their best interests at heart. Seb's is a wonderful place for boys to take risks, whether it's in the classroom, on a field or court, during a performance or in the lunchroom and know that their fellow Arrows are supporting them every step of the way. Headmaster Burke promises that our boys will be known and loved. I do not doubt that my boys truly believe that. And because of that belief, the boys are more confident and make deeper connections both in their faith and with the world around them. My husband and I feel that sending our boys to St. Sebastian's School has and will profoundly affect the trajectory of their lives in the most positive way possible!!!

Our family has been blessed to be a part of the St Sebastian's Community. We have two boys currently enrolled at the school, and words cannot express our level of satisfaction. The leadership, the facility, the campus, the curriculum, the athletics as well as the overall experience, continues to be amazing. I believe that every parent wishes the best for their children, but the only thing in life you can truly give them is their education. I feel strongly, by enrolling our boys at St Seb's, we have provided them with the best education available. I will forever be thankful for the opportunity our family has been given.

When I drive away from dropping off my son at Sebastian's, I do so knowing that he is in a safe, nurturing environment, where he is loved and will be challenged to be the best that he can be in every aspect of his life each day. He gets to school happy and when he gets picked up; he is usually tired but still happy. Since attending this school, I have watched my son's confidence soar to new heights, as he tries new things and excel at the things he tries. He knows he is growing and getting better and it's a beautiful thing to watch his confidence grow. This would not be possible without the unwavering support he receives from the members of the faculty. I am the parent of a graduate and a current student, and I couldn't be more pleased with this school. They have fulfilled all promises and surpassed my expectations in every possible way. On graduation day I embraced my son and whispered "well done" in his ear, and he responded, "Thanks for sending me to the best school". My second son who is currently a student looked over at me while I was driving home one day and said, "You made the right decision dad". If you are looking for a school that will bring out the best in your son while preparing him for college and its challenges, consider St. Sebastian's School.

As parents of five sons, we have been fortunate to have 4 sons attend St. Sebastian's with hope our youngest son attends next year. The entire community of faculty, teachers, coaches and parents is amazing. The culture of the school inspires incredible passion in the students to work hard and take care of each other while truly enjoying their middle school and high school experience. The St. Sebastian's experience has been an incredible experience for our entire family.

We currently have two sons attending St. Sebastian's School and although they are both very different children with different strengths and weaknesses, they have both loved their academic and athletic experiences at St. Sebastian's. The faculty is amazing; the students are wonderful friends and the entire St. Sebastian's community is filled with faith and compassion. We feel very fortunate to have our boys attend St. Sebastian's.

I feel so fortunate to have my two boys at St. Sebastian's School, where the order of the day is: Love God, Work Hard and Take Good Care of One Another. This would be a very empty decree if it wasn't something that is consistently exemplified and reinforced by the administration and teaching staff at St. Seb's. When my boys started at the school, we were promised that they would be "known and loved." It sounds like a tall order, but there isn't one person on staff that my kids couldn't go to for extra academic help, advice on handling a situation or simply to share a joke and a smile. The teachers are so invested in the success of their students, and as a parent I feel that I have true partners helping to grow my boys into kind, God-loving young men of character. They are challenged academically, spiritually and athletically at Seb's, and knowing that they are supported and loved has encouraged them to work harder and try new things.
