Company Overview

About Bessa Workplace Health and Safety

The Nationwide Workplace Health and Safety Leader with 30+ Years of Problem-Solving Success.

In more than three decades serving manufacturing, healthcare, biotechnology, construction and service sectors, Bessa Workplace Health and Safety has seen and solved virtually every imaginable problem – from histoplasmosis to welding fumes.

We work with safety officers, engineers, construction supervisors, property managers, lawyers, insurers and more nationwide – helping them identify, evaluate and control occupational hazards. Whether it’s indoor air quality, biological or chemical hazards, noise, or other workplace health threats, we have the expertise to address exposures, navigate regulatory requirements, and ensure healthy and safe operations for our clients. We also work proactively with our clients to develop and implement prevention programs, and provide expert testimony in litigation associated with workplace exposures and injuries.


A solution can look good on paper, but will it hold up on the assembly line or work cell, job site, laboratory or surgical suite? Over the years, we’ve built our reputation on the strength of our results – so much so that we’re known as the experts to call when a company has tried everything and nothing else works.

Our solutions succeed when others don’t because Bessa offers a combination of unique capabilities honed over 30+ years:

  • rigorous investigative work to seek out problems at their source

  • advanced science to devise practical solutions that truly work in the workplace

  • broad experience across diverse industries

  • human relations skills to create a cooperative culture, allay concerns and build “buy in” at every level

In all we do, our focus is forward-looking – always evolving to stay ahead of any new challenge, from regulation changes to managing the hazards of emerging technologies.
