Benson, Piombo and Company traces its roots to the formation of an accounting practice by Eugene A. Benson, Sr. in September, 1960. In the previous ten years Mr. Benson worked for Arthur Young & Company and the California Franchise Tax Board. On January 1, 1965, Neville Rich and Eugene A. Benson, Sr. formed the accounting firm known as Rich, Benson & Company. They conducted their practice in the San Francisco Financial District until June, 1980 when Mr. Rich withdrew from the practice of public accounting.
On July 1, 1980, Benson, Benson & Company, CPAs was established. The firm was founded by Eugene A. Benson, CPA, and his son, Eugene A. Benson, Jr., also a CPA. In May of 1981, Bernard E. Benson, CPA merged his client base into the partnership to practice accounting with his father and his brother in Marin County.
Effective January 1, 1990 Mr. Benson, Sr. retired from the firm as a partner after a 40 year career in public accounting. His sons continued the practice until 1995 when Gene Benson, Jr. resigned from the firm to pursue other business interests. Bernie Benson continued the practice until January 1, 2007, when he and Dan Piombo agreed to form Benson, Piombo & Company, CPAs. The combined working careers of the partners add up to more than 50 years of public accounting experience as of January 1, 2015. Benson, Piombo & Company, and its predecessors, has continuously provided accounting, tax and assurance services to its clients since 1960.
