About Us


atTAcK addiction is a 501(c)(3) non-profit group created in memory of Tyler Armstrong Keister after his accidental overdose. Our goal is to help young people realize the dangers of alcohol and drugs so that they and their families never have to experience the pain, tragedy and loneliness that accompany addiction.


Our mission is to raise awareness about the disease of addiction. Through educating communities, assisting families in their quest for information and supporting those in recovery, atTAcK addiction seeks to remove the stigma of addiction by effecting positive change in Delaware.


The main purpose of the group is to educate and bring awareness of addiction as a disease, rather than the stigma that is suffered in shame by the person with the disease and their loved ones. Attack Addiction seeks to educate by speaking at schools, prisons and any other venues where there is an interest in learning more about the disease of addiction. We strive to bring real and effective change to existing drug policy, We are not a support group, but we end up supporting those in recovery, those who have a loved one in recovery or those who have lost a loved one to the disease.
