Robert B. Krost Public Accountant is established in Pasadena in 1939
KROST, formerly Robert B. Krost Public Accountant, was established in 1939 by Robert B. Krost, who previously worked in the accounting offices of Lockheed Corporation. Venturing out to create his own firm he established many key contacts to help his clients through the various tax rules and regulations of the time. Some of these were with local IRS office managers and the head of the State Board of Equalization. Needless to say, these contacts were very important in resolving various tax issues for his clients which helped him grow his practice.

“At the beginning of the computer age (late 60’s) the firm saw the benefits that automation could provide to their clients and to the office. They installed one of the first automated accounting systems (Monrobot), which was a punched tape to tape system that created the general ledger and financial statements from tape machines reading to electric typewriters. As technology improved the firm upgraded to a minicomputer (Basic 4), a big improvement over the old tape to tape machine. Once this system was installed the firm was fully automated to handle all their clients accounting needs, in fact, we were the first accounting practice in the Pasadena area to be computerized.” — Rick Krost
