Trench Shoring Company History

Tom Malloy, launched Trench Shoring Company in 1973 to meet the unique shoring needs of general contractors, focusing on public works projects. Tom’s commitment became the company commitment - to help keep contractors safe in the trenches through excellent, consistent service . Tom was following his father's footsteps; in 1941, Emmett J. Malloy founded his Inglewood, CA, general engineering contracting business, taking the tough jobs too small for larger contracting companies to handle. Emmett’s focus on quality work and customer service helped his business become a leader in the Southern California construction industry.

In today’s business environment, personalized customer service is rare. Equally unusual is a third-generation family successfully guiding its company into a fifth decade of dedicated service to Southern California’s Construction industry. Malloy credits much of the company's recent expansion and success to the involvement of his children, Kevin (President), Bridgett (Vice President), Kelley (Vice President) and Ryan (Director). Each joined Trench Shoring Company after gaining valuable experience at other companies. And all four have brought their varied business backgrounds and passion to the business.
