History of the Columbus Office

The CoreSource Columbus, Ohio, office opened in 1976 as J.W. Didion & Associates, a third-party administrator for self-funded employee benefit plans.

It began as a small business on Busch Boulevard in Columbus, and has moved twice since then, to accommodate additional personnel, a growing book of business and, most recently, an enhanced office environment. In 1979, J.W. Didion moved to Huber Village Boulevard in Westerville, Ohio, because it needed more space, and, as a CoreSource office, it relocated to Dublin, Ohio, in 2004. Currently it has nearly 70 employees and administers health benefits to more than 140 clients in the Ohio area.
