Most Valuable CEO #1 – George Paz

#1 George Paz

Express Scripts, Inc.

St. Louis-based Express Scripts, a large pharmacy benefit manager (PBM), landed the top position in 2011, following previous years where it was ranked #57 and #47. The company rose through the ranks largely due to its success delivering growth through acquisitions, notably the PBM business of WellPoint in 2009, while maintaining and improving profitable operations. Express Scripts has proved skillful in integrating acquisitions, something few companies are capable of getting right.

CEO George Paz points to two factors that contribute to his company’s performance: its independence from Big Pharma and its diligence in using research to drive out waste and to make medicines safe and affordable in order to optimize health outcomes.
