Growing up in Texas, Dominguez described her childhood self as a "shy little girl" who was "caught between two worlds, two languages"[2] (Mexican heritage and American culture).

[citation needed] Dominguez attended Savannah College of Art and Design (SCAD) on a scholarship and graduated with a BFA in illustration.

[4] In a 2017 TedTalk by Dominguez, she explains that while this book may seem like a foreign world to the main American children audience, it provides minority groups within the chicanx realm the opportunity to see a familiar latinx world depicted, something that is not often seen in American children's books.

[citation needed] She has worked with authors such as Marsha Diane Arnold and Sonia Sotomayor to represent Latino/Hispanic characters and their overall culture with the intent of diversity and inclusivity in American children's books.

She is a member of Society of Children's Book Writers and Illustrators and PEN America.
