St. Louis-based Express Scripts, the largest pharmacy benefits management company in the U.S., said Wednesday that George Paz will retire as its CEO in May.

Tim Wentworth, who was named president of Express Scripts in February 2014, will replace Paz as CEO. Paz will remain chairman of the company.

Paz, 60, has been CEO for 11 years and oversaw its $29.1 billion acquisition of former competitor Medco in April 2012. Wentworth, 55, was the CEO of Medco's specialty pharmacy business before the merger.

With sleek, white furniture and an array of flat screen televisions, Express Scripts’ research lab has all the trappings of modernity and success. But for his part, Express Scripts CEO George Paz saw something else when he broke ground on his company’s headquarters a few years ago.  

When he stepped on the north St. Louis County field that would later become Express Scripts' campus, Paz saw dilapidated houses and sewer runoff. It wasn’t a sure-fire economic development opportunity.

Express Scripts celebrated the latest expansion to its north St. Louis County campus on Monday, another sign of growth for one of the nation’s biggest corporations.

The $56 million expansion includes an addition to its research lab and a new administrative office building. The project – which received millions of dollars worth of state and local tax breaks -- is expected to bring 1,500 jobs to the region within the next few years.
