In Santiago, she attended De La Salle School, competing in numerous sports, and studied Flamenco dancing for 8 years.

She returned to the sport to compete in the 2011 Pan American Games in Guadalajara, Mexico, where she took home the bronze medal with her doubles partner Angela Grisar.

She began traveling to the United States to play in more tournaments and train, knowing it would be difficult due to having no junior career and very little experience in high-level competition.

In 2014, Muñoz moved to the United States, settling in the San Francisco Bay Area to receive more training and play in more tournaments, while also furthering her educational aspirations of becoming an accountant.

In 2016, Muñoz received a two-year scholarship to attend Colorado State University Pueblo to finish her degree in Business and Accounting, and to play for their nationally-ranked racquetball program.

Muñoz has played for Chile in numerous international competition winning several medals, including at the World Championships and the Pan American Games.
