PRA went public in 2004 and is now among the world’s largest CROs. David served on PRA’s Board of Directors, and, from 1991 to 1994, as head of Business Development before being named General Counsel. In these capacities he was involved in the planning and implementation of all phases of pharmaceutical clinical trials across a wide range of indications.

After leaving PRA, David became associated with the University of Virginia in an initiative to more closely link high-technology industry with research. He met Professor John Gainer and the two launched Diffusion Pharmaceuticals shortly thereafter. David has remained involved with the University’s efforts to encourage the spin-out of new high technology companies.

David is a founding director of publicly traded Virginia National Bank, and served on its board until May 2012.
