Robert Pack, PhD, MPH is Professor of Community and Behavioral Health, Associate Dean for Academic Affairs in the College of Public Health at East Tennessee State University, Director of the ETSU Addiction Science Center and Co-Director of the Opioids Research Consortium of Central Appalachia (the ORCCA).

The Center grew out of a university and community collaborative that was started in 2012 to address the regional problem of prescription opioid abuse. In 2017, the Center partnered with the region's largest health system, Ballad Health, and the region's largest mental healthcare system, Frontier Health, to open a non-profit opioid treatment program in the Northeast Tennessee region. The clinic, called Overmountain Recovery, is the only clinic in the region that offers methadone and buprenorphine maintenance therapy, and counseling for opioid use disorder. The clinic has been open since October 2017 and currently serves more than 300 clients in the region.

In 2018 the ETSU Center won the United States Public Health Service award for Excellence in Interprofessional Education Collaboration. In 2019, Pack serves as a member of the boards of directors for Nashville-based OneTennessee Health,and chairs the board of directors for Overmountain Recovery. At the national level, in 2019 he served on the Appalachian Regional Commission Substance Abuse Advisory Council, on the Technical Expert Panel for the Office of National Drug Control Policy, and chaired the Association of Schools and Programs in Public Health (ASPPH) Task Force on Public Health Approaches to Control the Epidemic of Opioid Use Disorder.
