Hewitt Associates Inc. announced it has acquired Senior Educators Ltd.

Senior Educators is a medical insurance exchange that helps retirees buying supplemental Medicare insurance products.

“The retiree health insurance market represents an attractive growth opportunity for Hewitt as more employers discontinue retiree medical coverage or look for ways to provide retirees with cost-effective alternatives,” said Russ Fradin, chairman and chief executive officer of Hewitt Lincolnshire, Ill., an employee benefits consulting firm.

Founded in 2005, Senior Educators, San Francisco, markets insurance in 50 states and in the District of Columbia.
