Thornton Donovan School was an incredible launchpad for me. My teachers were like a team of superheroes, backing me up and pushing me to reach new heights. The coursework was no joke, but it gave me a huge head start on college prep and life after college. From doing college courses and gaining college credits in high school, to traveling internationally and staying with amazing host families in Venice and Sicily, to helping to rebuild homes with Habitat for Humanity after Hurricane Sandy, to representing Chile with our Model UN club, to contributing to the School newspaper, to performing in the Arts House Cafes, to making my own ceramics with the school's kiln and especially going on Glory Days to immerse myself in the world's religions, I'm deeply filled with gratitude for my journey at Thornton Donovan School!
