Ricciani, Jessen, & Griffey operated until 1988 when Mr. Jessen left to pursue work in the private industry.

The firm name was changed in 1990 to Ricciani & Griffey and operated with increased staff including two full-time CPAs, in addition to the partners, two to three client services staff and one to two administrative staff until 1993 when Julie W. Mathis was admitted as a partner.

The firm known as Ricciani, Griffey & Mathis operated until 1995 when Roger K. Griffey retired and Andrew G. Jessen rejoined the firm as a partner.

Our Philosophies

We promote the firm concept that clients are served by the Firm, rather than by individuals.  We refer to "our clients" rather than "my clients."  Opinions and recommendations are stated as "our recommendations" and "we believe." We work together to service our clients using our collective experiences and knowledge.

Here are some of our key philosophies:

  • Produce work of the highest quality
  • Take personal interest in our clients
  • Encourage employees to service their community
  • Strive to be the kind of firm employees and clients are proud to associate
