We know what it's like to be the only girl in the room
Sisters in STEM is a student-led nonprofit born at Saguaro High School. We build programs that show young people, especially girls, that they belong in STEM.
Born from a cancelled event
In 2018, a beloved local STEM event for girls was cancelled. Three Saguaro High FIRST Robotics Competition students refused to accept that. In just three weeks, they built their own inaugural event from the ground up.
The response was overwhelming: over 200 attendees, 45 student volunteers, and more than 50 Phoenix-area STEM professionals and academics came together for a day of learning and inspiration.
That momentum has only grown. Today, Sisters in STEM runs multiple programs serving students across greater Phoenix, backed by Math and Science Academy leadership, Scottsdale Unified School District administrators, and a growing network of STEM professionals who believe in this work as much as we do.

"Jada Saves the Day!"
Our founder Kayli Battel wrote a book about a girl who cracks a cybercrime, and now our volunteers read it to K–5 classrooms across Phoenix.
