Laurel Cain

Environmental & Intake Inspector

For the past decade Laurel has worked in the environmental field to reduce toxins, implementing sustainability certifications for building materials, and recently joined HBS as an environmental inspector.

Laurel has a passion for helping people to create environments that enrich their lives. Prior to her work in the environmental field, she was a commercial artist creating decorative paint finishes. After focusing on the aesthetic aspects of spaces, her interests evolved into creating more healthful spaces motivated by the poor air quality that results from many building materials and coatings.

Laurel holds a B.A in painting and intensive coursework in chemistry from Portland State University and the Evergreen State College and is a Certified Sustainable Building Advisor. She spends her free time tending to her garden, creating art, and sailing on the San Francisco Bay.
