Robert Casilla was born in Jersey City, New Jersey to parents from Puerto Rico. Like many children, Robert always loved to draw. As the new kid in his second grade class, he recalls doing a drawing of two birds with colored chalk on construction paper. His teacher noticed the drawing and then told the class, "We have an artist in the class!" Robert is thankful to her and all the teachers that motivated and helped him realize he had talent as an artist. Although he grew up in New Jersey, he did get to attend school in Puerto Rico as a fourth grader.
