Who We Are & Why We Fight

Opioid-related deaths continue to rise in Tennessee. ONE Tennessee exists to bring together all the important players – medical professionals, lawmakers, community leaders, and families – to educate and collaborate for better health systems.


In 2017, over 1,700 Tennessean lives were lost to overdose deaths – more than motor vehicle accidents.


Nearly 1,000 Tennessean newborns required hospitalization for opioid withdrawal symptoms or Neonatal Abstinence Syndrome (NAS) due to intrauterine opioid exposure.


$250,000 was awarded to the Tennessee Department of Health to assist in the launch of what is now ONE Tennessee.

Our Story

In 2017, the Tennessee Department of Health hosted a summit called “Turning the Tide,” to address the opioid epidemic plaguing the state. It was here, that medical and healthcare professionals gathered as one voice, to strategize on ways to provide safe & effective pain management to our citizens. The outcome of this meeting led to the formation of a nonprofit healthcare collaborative created specifically to serve as a centralized resource for coordinating and connecting efforts to decrease opioid misuse and abuse in Tennessee.

We are ONE Tennessee.
