Preston Companies is proud to announce that we have been recognized as one of the Top 100 Corporate Philanthropists in the Bay Area.

This honor, presented by the San Francisco Business Times and the Silicon Valley Business Journal, recognizes organizations that demonstrate a strong commitment to philanthropy. Rankings are determined through their contributions to Bay Area-based charitable organizations in the community. In the 2025 fiscal year, Preston donated approximately $181,000 to local non-profits and provided high school students with hands-on experience through a mentorship program.

“I have the privilege of seeing firsthand that our greatest strength is our people. This recognition is a reflection of our employees, leadership, and community partners who generously give their time, talents, and resources to make a meaningful difference,” said Vice President of Human Resources and Marketing Lauren Trekell. “At Preston Companies, we believe success is measured not only by what we build, but by the positive impact we leave on the communities where we live and work.”

Preston’s impact is made possible through the generosity, heart, and dedication to service that our employees lead with. From mentoring young talent to collaborating with local organizations, Preston employees effect positive change in their own backyards. We remain committed to investing in the Bay Area so that our nonprofit partners can thrive and focus on their mission to provide essential services to our neighbors.

Earning this recognition reinforces our commitment to being not only a leader in our industry but also a place that, for the past 55 years, is dedicated to giving back to the area where we first established ourselves and continue building for.
