My’Kal Stromile was 14 the first time he stood in a studio at Jacob’s Pillow. It was 2017, the last year Anna-Marie Holmes ran its classical ballet program. Before he became a dancer, he remembers being a kid who wanted to be a teacher. He would come home from school and set up a classroom in his bedroom, including a whiteboard and copies of the teacher’s edition of a Houghton-Mifflin textbook given to him by his brother-in-law at the time.
