Firm History

Rowles & Company, LLP was established in 1928 by Leonard B. Rowles, Sr., CPA.  Mr. Rowles was not only a practicing attorney-at-law, but also spent several years with the Maryland State Bank Commissioner as Senior Bank Examiner.  His experience, coupled with his skills as an instructor of accounting at The Johns Hopkins University, provided the foundation for the development of his accounting practice.

In its early years, Rowles & Company, LLP primarily offered auditing, accounting, and tax services to commercial banks.  However, over time the practice became more diversified and today Rowles & Company, LLP offers a variety of auditing, accounting, consulting, and tax services to financial institutions, engineering and architecture firms, small businesses, not-for-profit organizations, individuals, estates, and trusts.

In August of 2021 Rowles merged with YHB. The merger will make the Baltimore office YHB’s ninth location. As a Regional Leader and Fastest Growing Firm in the United States, the YHB and Rowles merger helped strengthen both Firm's foothold as a multiregional accounting firm with offices spanning across Virginia and Baltimore.
