Her training also includes programs and intensives in the United States, including The Washington Ballet, Steps on Broadway, and Point Park University, among others.
Stella has performed in numerous classical and contemporary productions in Puerto Rico and the U.S., dancing both corps and featured roles.

In addition to her classical foundation, she is a versatile performer with training across multiple styles, including ballet, jazz, tap, ballroom, hip hop, and musical theater.

Her passion for teaching and leadership began in high school, where she was president and choreographer of her dance team.
