About Us

Founded on November 28, 1955, Atomic Credit Union has a rich history rooted in serving hardworking individuals. Originally established to support employees and retirees of the Atomic Plant site, the credit union has grown far beyond its early foundations. In the early 1990s, we took another major step forward with the acquisition of Southern Ohio Savings Credit Union, allowing us to extend membership to anyone who lives, works, or worships in Adams, Brown, Gallia, Highland, Lawrence, Pike, and Scioto counties. This growth brought new branch locations and ATMs to communities like Waverly, Portsmouth, and Piketon, fueling our mission to provide accessible, member-focused financial services.

Atomic Credit Union is stronger than ever, with 18 branch locations and over 80,000 members who trust us with their financial futures. Our commitment to financial empowerment is reflected in our core message: #ACU4U—A Credit Union for You. Whether through personalized banking solutions, local sponsorships, community partnerships, or our extensive financial education programs, we are dedicated to improving the lives of those we serve.

Atomic Credit Union continues to expand its reach and services. On November 1, 2024, we acquired Scioto County Federal Employees (SCFE) Credit Union in Portsmouth, Ohio, enhancing financial services for SCFE members while deepening our community impact. We also installed a new ATM at Bloom-Vernon Local Schools in South Webster, OH, improving financial accessibility for students, staff, and residents—an initiative inspired by former Student Advisory Board member Hunter Slack. We also opened our 18th branch location in Lancaster, Ohio, further expanding our commitment to accessible banking solutions.

We are also proud to operate the largest Student-Run Credit Union Program in the country, equipping young learners with essential money management skills. With close to 100 student-run branches and nearly 1,000 student volunteers gaining hands-on experience in banking and leadership, we are shaping the next generation of financially confident individuals. Understanding that millions of children grow up without access to financial services, we invest over $1 million annually in financial education—starting as early as preschool—to break cycles of financial insecurity and build brighter futures.

Our commitment to empowering students extends to higher education, as we awarded $31,500 in scholarships last year to help graduating seniors take their next academic step. Our leadership in financial literacy was also nationally recognized in 2024 when Atomic Credit Union earned 1st place in the Desjardins Financial Education Award.
