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.
