For 10 years, Slave 2 Nothing® has remained committed to its unwavering mission of restoring lives and freeing people from being enslaved to any substance or person.

My husband, Sean, and I felt called to step into this work. We saw how we could help raise awareness and, ultimately, contribute to educating and assisting with solutions to eliminate substance abuse and human trafficking.

We’re proud to say that since its founding, Slave 2 Nothing has granted over $23 million to organizations fighting substance abuse and human trafficking in the 10 states IN-N-OUT® does business. We cover all costs associated with Slave 2 Nothing, ensuring that 100% of every dollar raised goes to carefully vetted organizations supporting our causes.

None of this would be possible without you, and we’re deeply grateful for all the support over the last decade. To learn more about how your gift helps individuals experience freedom, please visit slave2nothing.org.
