This episode is part of our Skilled Labor Series hosted by MCJ partner, Yin Lu. This series is focused on amplifying the voices of folks from the skilled labor workforce, including electricians, farmers, ranchers, HVAC installers, and others who are on the front lines of rewiring our infrastructure.

Today’s guest on Yin Lu’s Skilled Labor Series is Alana Guzzetta, a 15-year veteran of the concrete-making business. Alana started as an intern, worked her way up to being a lab technician, and now runs the R&D lab at Vulcan Materials. She has both a bachelor's and master's of civil engineering.
