Professor Christie is Mia’s cello teacher. She is a professor of music at a local college, and a friend of Mia’s Dad. Though she is skeptical of young Mia’s abilities at first, after listening to her practice the cello, she agrees to take over her studies and find her other students to play with. Professor Christie encourages and coaches Mia to apply to Juilliard, and believes she has a real chance to become a professional musician.
