LAFAYETTE — The Schumacher Group is planning a $19 million expansion of its headquarters in Lafayette, Gov. Bobby Jindal announced at a news conference today.

The expansion of the company’s Lafayette headquarters will add 600 new jobs with an average salary of about $62,000, and more than 1,400 new indirect jobs, Jindal said.

The expansion was made possible in part through the state’s Mega Project Fund, which will reimburse the company for up to 50 percent of the expansion cost, or up to $9 million, Jindal said.

Over the next decade, Gautreaux said, those 600 jobs will have an economic impact of $2.45 billion on the Gross Domestic Product of this parish, said Greg Gautreaux, president of the Lafayette Economic Development Authority.

“That’s phenomenal,” Gautreaux said. “This is the biggest project announcement in a decade.”

The Schumacher Group, founded in Opelousas in 1994 by Kip Schumacher, contracts emergency room services to hospitals around the country. The company is now the third largest such company in the country, Jindal said.

The company contemplated moving to Houston, Dallas and Atlanta, but ultimately chose Lafayette.

The expansion is expected to begin in 2012 and will be completed by 2014, Jindal said.
