About Sierra Consultants
In the late 1980s, early in his environmental career, David VerSluis watched other firms recommend unneeded testing and run up unnecessary million-dollar cleanups, while the client had no way to know the difference. He started Sierra in 1993 and tried to hold himself to a higher standard — but for years, that standard was just his word.
In 2012, a lending client who believed in Sierra's integrity suggested making it a guarantee instead. That's how Clean-or-Free began: if an RSRA finds elevated risk, your fee is waived, and Sierra has nothing to gain by pushing a report you did not need. Read the full story.
