Since 1985 we’ve supported the National Institute of Environmental Health Sciences and have provided more than 1,600 quality assurance audit reports that the client has used to assess the quality of toxicology studies they sponsor.   

Over the last year our employee owners reviewed several studies involving per- and polyfluorinated substances (PFAS) compounds, or “forever chemicals”, that have been in the news. In addition, our team has reviewed several draft manuscripts that their researchers are preparing for publication in scientific journals.  This new assignment illustrates their confidence in our team to determine the accuracy and completeness of a toxicology research paper.
