Isaias Villa Galvan

Safety Director

CSP, CHST

Before entering construction safety, Isaias began his career as a wildland firefighter, where he developed a calm, confident approach to risk management. That experience made his transition into safety and construction management a natural progression. He has since proven himself a strong leader, capable of guiding teams of safety professionals and fostering a culture rooted in accountability and safe work practices, making him the perfect fit for Safety Director at GLY. Outside of work, Isaias stays active through Brazilian Jiu Jitsu, strength training, running, hiking, and golfing, and he enjoys spending downtime reading. Despite calling himself the world’s worst swimmer, swimming remains a favorite hobby [an unexpected passion that perfectly reflects his willingness to embrace any challenges he is faced with].

Melanie Cochrun

Director of Marketing+Communications

CPSM

A healthy dose of serendipity led Melanie from the Peace Corps third world to the A/E/C integrated world, where she discovered a love for working with the people behind the concrete. Nearly 20 years later, she is contributing and receiving ideas and inspiration for marketing, communicating, and developing business as the Director of Marketing + Communications at GLY! A self-described thinker, linker, and obstacle shrinker, Melanie likes to approach her work with these three questions: Who is our audience? What do they need? How can we reach them and develop trust?
