    I decided to transfer to Justin Siena for my Senior year of high school, and it was the best decision I could have made. I joined the leadership class, which got me involved right away serving my community, and really made me feel like I was part of the school. The academics are rigorous, but the focused environment is really wonderful, and it is quite encouraging to see my peers working hard. The community aspect of Justin Siena is really the most unique aspect of this school. Relationships are emphasized and I truly feel that I have gained more skills in developing good relationships with everyone around me, whether it be teachers, coaches, parents, or other students. This school is special because it not only teaches students to work hard and prepares them for higher levels of education, but it also builds character and provides a structure for students to create balance in their lives and become good people through their everyday interactions.

    Justin-Siena highschool is an establishment that offers its student with the ideal high school experience. Everyday seems like an opportunity for growth and discovery at Justin-Siena. The high school is ever expanding in its curriculum and pushing students to think on deeper levels on the daily. As a senior of the class of 2020, I have seen the school go through lots of changes yet every step along the way I was never sold short on my chance to learn. While the school's competitive nature and culture sometimes conflicts, I have never felt out of place among all the kind students and faculty. Everyone at Justin-Siena makes an effort to be kind and considerate of others. As a scholar who is very interested in academia, the school offers many AP and honors courses especially in the sciences. The love for teaching from STEM teachers is apparent and makes Justin-Siena a great school for families looking for the best private education in the Valley. #GoBraves #AllHeart
    Justin-Siena let me find my talents, hobbies, and interests through their wonderful performing arts and sports programs. I did not know what I wanted to pursue in college until I took an Athletic Training class my junior year and got to work on the field, in the action. I excelled in track and field and found my passion for dance under the great Lisa Clark. The student ambassador program helped me polish my public speaking and build my resume, as well as make connections with faculty and parents.
