From the first day I came to TA I felt like a new me, and a new life began for me. The dorm became my second home and the other students my second family. I loved every dorm parent, teacher, counselor, and every staff member that helped me grow and taught me a new way of learning. I left home as a kid and came back a man, and I'm so grateful for it. I am and will always be a Trojan!
