Yissel Hernandez

Assistant Site Lead


Hello, my name is Yissel Hernandez. I am a college graduate from the University of Illinois at Urbana-Champaign earning my degree in Psychology. I enjoy listening to all sorts of music with the hope of one day getting the chance to learn to play piano. This upcoming school year will be my fourth year working with J at School. Every child who I have been given the opportunity to meet and work with knows how much I enjoy my job. What makes it really enjoyable is how carefree, silly, caring, sweet, curious, and innocent they are. Not only are their characteristics awesome but when kids start seeing you as a friend is truly an amazing feeling. Knowing you have gained their trust and they can rely on you with anything is honestly the best feeling with working with children.
