The AAPI Student Union at her high school in an Instagram post said that Gwen was a leader and a friend. "She was a highly accomplished student at North, being involved in various activities, from Changemakers, band, NHS, math team, and tennis, all while being on the high honor roll. Gwen and her father @repseancasten recognized the importance of protecting the environment and the dangers that arose if we kept polluting our planet."

DuPage County board member Dawn DeSart didn't know Gwen Casten but recently on social media called her a "shero" for organizing a shooting-related first-aid course for her high school classmates. She initiated 'Stop the Bleed' training in her school, which taught students how to pack a gunshot wound in a fellow student in case of a school shooting, according to the Chicago Tribune.
