An honor student with memberships in every academic club and student government group she could get her hands on, Retta was well on her way to becoming a cliché. But upon graduating premed from Duke University with a degree in sociology, Retta decided to take a year off before medical school and worked as a contract chemist for GlaxoSmithKline.
