Meet Our Fellows
Addiction Medicine Fellows
for the 2025-2026 Academic Year
Alison (Alie) Holt, MD, MA
Medical School: Lewis Katz School of Medicine at Temple University
Residency Program: University of North Carolina at Chapel Hill
Primary Specialty: Family Medicine
Interests: Harm reduction, integrating addiction care into primary care, increasing access to MOUD and other evidence-based treatments in jails and prisons
Why I Chose the UNC Addiction Medicine Fellowship Program: I chose to continue my journey at UNC because the breadth of training opportunities—from adolescent medicine and reproductive health to pain management and beyond—mirrors the comprehensive, person-centered approach to addiction care that I value as a primary care provider. I believe that supporting people with addiction means seeing the whole person, and that philosophy is deeply woven into the fellowship at UNC. I’ve had roots in the Triangle for over a decade, and during that time, I’ve developed a strong respect for the people and communities across North Carolina. It’s a real privilege to continue learning from and caring for patients here, and I’m excited to grow alongside them in the years ahead!
Nathaniel (Nate) Erskine, MD, PhD
Medical School: University of Massachusetts Chan Medical School
Residency Program: University of North Carolina at Chapel Hill
Primary Specialty: Preventive Medicine
Interests: Healthcare access, pain management, preventive services among those with substance use disorders
Why I Chose the UNC Addiction Medicine Fellowship Program: During my residency rotations, I was struck by the collaborative and compassionate ethos of the UNC Addiction Medicine team. I repeatedly witnessed addiction attendings, fellows, case managers, social workers, peer supporters, pharmacists, and support staff going the extra mile to help patients. I am excited to continue my training with a group that is so committed to empowering our patients.
