Background
Home→About Us

After over a decade of experience in water management and chemical water treatment, Precept Environmental, Inc. was founded in 2008 by Britt Rodgers and Johanna Astaire with the goal of providing customers unbiased solutions in water management. They were dedicated to building a business that was based purely on consulting and support services, free of any ties to chemical or equipment solutions, or an in-house laboratory. By prioritizing our customers’ best interests, we have earned their trust and loyalty. These founding goals remain deeply rooted in our business model and will continue to dictate how we conduct business.
