Tom Bannard knows what it’s like to recover from alcohol and drug problems on a college or university campus that offers more temptation than support. Five years after becoming coordinator of Rams in Recovery, Bannard has built the collegiate recovery program at Virginia Commonwealth University into a model and a mentor for other Virginia colleges and universities. “We are kind of a flagship,” said Bannard, 36, who relied on a similar program, Hoos in Recovery, when he returned to UVA in 2008 after undergoing rehab for substance use disorder.
