In the last six decades Rudolph and Sletten has constructed more than 3,000 projects across our five California offices, from research centers designed to cure diseases, to institutions that educate future generations of leadership. As we’ve grown, we’ve built all aspects of life science, higher education, healthcare, high-tech, government and everything in between.

Just like the buildings we construct, our reputation is built to stand the test of time. Our success is owed to our diverse, talented personnel combined with our technological expertise, honest estimates, innovative schedules, and ethical business practices.

We're excited to see where the future takes us. Between new building and construction technology, better earth-friendly materials and techniques, all our phenomenal employees and the amazing people we get to work with, we’re looking forward to another great decade for Rudolph and Sletten.


As with any good Silicon Valley start-up, Rudolph and Sletten started in the family garage. 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.
