About Us

We are located in Fairfield, Ohio, a northern suburb of Cincinnati. We do accounting and tax preparation for small businesses and non-profit organizations nationwide.  The company was started in 1983.  In December 2010 we purchased the income tax practice of Roger Grein, CPA in Reading, Ohio which prepares 800 personal income tax returns annually.  We operate that business as Grein & Potter, CPA’s. In 2015 we acquired the accounting practice of William J. Lenihan, CPA and merged it into our Fairfield office.  We prepare over 900 personal and business income tax returns at the Fairfield office. We do monthly and yearly accounting for over 100 small businesses and non-profit organizations.
