Mark Thierer

Chairman & Chief Executive Officer
Catamaran Corporation

Mark Thierer is the chairman and chief executive officer of Catamaran, one of the nation’s largest pharmacy benefit managers, serving more than 25 million members. Thierer was instrumental in reducing how pharmacy benefits are managed by successfully merging two industry-leading PBMs—SXC Health Solutions and Catalyst Health Solutions—to create Catamaran.

Thierer joined SXC in 2006 as president and chief operating officer and was named president and chief executive officer in 2008, then chairman of the board in 2011. During his time as chief executive officer, the company posted a compound annual growth rate of 50% and had a 50-fold increase in shareholder value. Prior to joining SXC, Thierer led the evolution of Physicians Interactive, a division of Allscripts Healthcare Solutions as it repositioned itself from a supplier of electronic detailing to a full-service provider of online marketing and educational tools for physicians.
