In 1959 Onslow H. 'Rudy' Rudolph formed a small contracting company, O.H. Rudolph, General Contractor, based out of his garage in Los Altos, California. Starting with just a small amount of savings, a pickup truck and two employees, Rudy quickly built a business that became known for its ability to deliver the highest quality work on-schedule and within budget. In 1962, Kenneth G. Sletten joined the business as partner and the company was renamed Rudolph and Sletten, Inc., General and Engineering Contractors. Rudolph and Sletten has grown from a small business to a vital corporation with current employees numbering over 800. Over 85 percent of its business is from repeat clients. Today, Rudolph and Sletten is the 24th largest domestic general building contractor in the nation as ranked by Engineering News Record. With its corporate headquarters in Foster City, the company also has regional offices in Sacramento, Irvine and San Diego, California. .
