The Atomic Credit Union was founded November 28, 1955, nearly 25 years after the credit union movement began in Ohio. Originally, the credit union was established to meet the financial needs of "all retired or permanently employed personnel engaged in the operation of; maintenance of; or construction at the Atomic Plant site," additionally, immediate family members were also permitted to join the credit union. The credit union's field of membership remained status quo until a small credit union in Scioto County, Southern Ohio Savings Credit Union, Inc became insolvent and was presented to Atomic in the early 1990's as a merger opportunity. Although Southern Ohio Savings Credit Union, Inc was relatively small in asset size, it held a very lucrative field of membership charter.
Upon completion of the merger, Atomic opened its doors to all living, working or worshiping in the following counties: Adams, Brown, Gallia, Highland, Lawrence, Pike and Scioto. As a result of this, branch offices and ATMs sprung up in Waverly, Portsmouth, and Piketon to support the growing needs of our new members. Throughout the following years, the Atomic board promoted community growth opportunities as a strategy for future success. The board realized the importance of building the credit union with multiple employer based groups and community charters. With this strategic vision, the credit union's current President and Chief Executive Officer, Tom Griffiths, secured an eighth community charter in Jackson County in 2000, and has built the employer based sponsors in excess of 170. The Jackson office has since been established, in addition to our sixth office in the Wellston, Ohio market. One of our largest employer based groups, General Mills, and Atomic joined forces to bring convenient financial services to the employees, while promoting a community accessible branch.
In 2007, the ninth community charter of Ross County was obtained with future plans to venture into the Chillicothe market. 2008 marked a historic year for the credit union as Atomic opened its seventh branch in the heart of Lucasville, in addition to a new 18,600 square foot facility serving as the Piketon branch and Corporate office. Atomic Credit Union also opened its eighth office expanding services to the residents of Chillicothe.
In 2009, Atomic Credit Union expanded to the Hocking Valley Region due to the merger and acquisition of Hocking Valley Credit Union. As a result of the merger, Atomic acquired two locations in Athens and Logan and added five counties to its field of membership. Community charters gained through the merger are Athens, Hocking, Meigs, Vinton and Perry counties in addition to already established Adams, Brown, Gallia, Highland, Jackson, Lawrence, Pike, Ross, and Scioto counties.
Atomic opened its eleventh office in Minford in March of 2012.
