Founder Louis J. Kruse was the son of a German immigrant who came to California to mine the gold fields of the Sierra foothills. Louis was born in Grass Valley in 1889, and when his father died a few years later in a mysterious mining accident, the family moved to San Francisco. Growing up in the city, Louis enjoyed working with his hands and studied gas fitting at Lick-Wilmerding, which was then a trade school.
After the great earthquake of 1906, Louis realized the vast potential for tradesmen in the East Bay and moved to Oakland. He built a home in the Rockridge neighborhood. In 1916, he opened his plumbing shop on College Avenue. After his death in 1946, his son, Edward H. Kruse, directed the fast post-war growth of the company. David Kruse, now Chairman of the Board, served as President from 1986-2015.
The firm now works in all five Bay Area counties and is managed by third and fourth generation leaders Andy Kruse, Nathan Kruse, Ben Kruse and Will Kruse. “We need youth and the energy it brings” Andy Kruse says. “When our grandfather was young, he had a vision and this next generation does too."
