Romina Calatayud was three years old when she realized girls and boys were not treated the same way. So she started Girls United, which gives girls around the world equal access to sports and helps them feel confident on and off the pitch. You can find Romina in the new book Rebel Girls: 100 Inspiring Young Changemakers! We're celebrating all September long with two special Changemakers podcast episodes each week. Preorder Rebel Girls: 100 Inspiring Young Changemakers wherever books are sold to learn about how girls just like you are changing the world. This story was produced by Joy Smith with sound design and mixing by Reel Audio. It was written and edited by Abby Sher. Narration by Ana Osorio. Thank you to the whole Rebel Girls team, who make this podcast possible. Stay rebel!
