Katie Ring is a self-defense instructor, content creator, personal trainer, and advocate for victims committed to helping people feel safer, stronger, and more prepared in a world that often makes them feel otherwise. She grew up in San Francisco and first turned to martial arts after a series of assaults on women in the city pushed her to take action. That moment sparked a mission that evolved into a fast-growing digital platform focused on practical, real-world self-defense – especially for women.

With over 1.2 million followers, 30 million likes, and millions of views across socials, Katie has become one of the fastest-rising voices in true crime. While she first gained attention for her safety strategies and situational awareness content as @the.self.defense.girl, she has since expanded into breaking down active investigations and headline cases for a wide audience. Her in-depth coverage of the Karen Read trial went viral and was featured on Good Morning America, positioning her as a credible new force in the genre.

Her rise in the true crime space continues as host of America's Most Infamous Crimes, a new Crime House original video and audio series launching March 24. Each week, the show dives into one of the most notorious cases across three episodes, released Tuesday through Thursday, breaking down what happened, how investigators closed in, and why these crimes still haunt America.

Driven by a deep commitment to victim advocacy, Katie continues to build a powerful platform dedicated to education, empowerment and giving people the tools and resources to protect themselves and each other.
