Welcome to the About OPERS section

This section contains a wealth of information about the state's largest pension system -- from legal policies, government relations and corporate matters to vendor and employment opportunities. A snapshot of OPERS is provided at history and background.


Since 1935, OPERS has meant security and peace of mind to millions of Ohio’s retired public workers and their families. OPERS provides retirement, disability and survivor benefit programs for public employees throughout the state who are not covered by another state or local retirement system.

With defined benefit and health care investment assets of $99.6 billion as of Dec. 31, 2017, OPERS is the largest state pension fund in Ohio, and the 12th-largest public retirement system and 15th-largest retirement system in the U.S.

Located in the heart of downtown Columbus -- Ohio's capital city – OPERS is blocks away from the Ohio Statehouse.


OPERS serves more than 1 million past and present Ohio workers. This includes active (working) members, benefit recipients and former public workers who maintain an account with the system.
