DioGenix, in Gaithersburg, Md., was founded in 2009 after CEO Larry Tiffany and his senior management team saw a clear clinical need: monitoring disease progression of multiple sclerosis (MS). Tiffany has an extensive background in biotech, as an IP attorney, and as a senior executive at small and mid-size biotech companies. Before DioGenix, he was senior vice president and general manager of genomics for another genomics research company, Gene Logic.
