The firm was founded as Hirth, Norris and Company, formed in 1976 upon the merger of the Charles W. Hirth Company and James E. Norris, Certified Public Accountant. Prior to the merger the Charles W. Hirth Company had been serving clients in the central Ohio area since 1964 and James Norris had founded his private practice the year prior to the merger. The groundwork invested by Mr. Hirth and Mr. Norris continue to inspire the firm today. Mr. Hirth retired in 1999 after an extensive 35 year career and Mr. Norris retired in 2014 after over 40 years in the accounting and tax business. We thank both men for their service to clients, to their family and to the community.

The heart of the firm is the partners. Their experience allows for innovative approaches in serving our clients. They have a wide base of experience in client services. At the same time, each has developed complementary specialties to satisfy our client’s needs.

Our staff is selected to assist and support the partners in order to offer clients immediate personal attention at reasonable fees. Each associate is trained in accounting, auditing and taxation on a continuous basis.
