It’s been 20 years since the mass shooting at Columbine High School in Colorado. We’re joined by Austin Eubanks, who was a student at the school and was injured that day. He’s spent the past two decades becoming an expert in addiction treatment, after becoming addicted himself in the months and years after the massacre. We’re also joined by the CEO of the David Lawrence Center, who is bringing Mr. Eubanks to town for a mental health symposium on Saturday, March 23 that will explore the long-term damaging effects of trauma.
