With just about every corner of California experiencing intense construction activity and worker shortages, it’s an employee’s market. But the young people profiled in this year’s Top 20 Under 40 list clearly do not rest on their laurels. Instead, these industry professionals manage megaprojects, dedicate themselves to improving their communities and foster teamwork within their organizations.

Selected from around 60 applicants, the 20 individuals profiled here include innovators, community leaders and industry mentors. Some balance a demanding job with family commitments. And several have turned serious health obstacles into inspirational examples for others.

A majority of the Top 20 honorees incorporate energy efficiency in their design or construction activities, and several mentor or teach sustainability strategies to the next generation coming into the industry.

In its sixth year, the Top 20 Under 40 competition accepts entries through an online system for those under the age of 40 who work within the construction industry in California and Hawaii. Submitters provide information on a candidate’s work experience, industry leadership activities, efforts to improve the built environment and service to the broader community.

An independent panel of five judges evaluated the entries. One was a past Top 20 Under 40 honoree: Christopher Taylor, Southern California division leader with Southland Industries. Other judges included Danielle Feroleto, president of Small Giants; Mike Humphrey, San Francisco regional manager for DPR Construction; Brent Leif, project executive and branch manager of Hunt Construction Group’s San Francisco office; and Alan Laurlund, senior vice president of XL Construction.

Any candidate who worked for the same company or an affiliated company as a judge was assigned to a different judge.
