This month, the company begins major upgrades to Stockton’s Banner Island Ballpark, home of the Stockton Ports, to align the facility with Major League Baseball standards. HAGGERTY also recently delivered the new Fremont Cadillac dealership, a ground-up project that strengthens its portfolio in the auto and retail sectors across Northern California.

Beyond construction, the company actively supports the San Joaquin and Sacramento community by investing in local youth and those in need. “We believe in building more than structures,” says Haggerty. “We support growth through volunteer work, mentorship and donations that help educate and uplift the next generation.”

HAGGERTY Construction remains committed to strengthening the industry and the community while delivering the highest level of service. Haggerty concludes, “We look forward to another 15 years and more of supporting our people, our community and our industry’s growth within the greater Northern California area.”
