hillary Waterhouse, MPH, CIH owner and Principal

I’m a former OSHA Compliance Officer and Certified Industrial Hygienist with more than fifteen years of experience. I have an extensive background doing complex workplace health and safety evaluations, OSHA litigation, and federal agency consulting. I’m also the current president of the Eastern Upstate New York AIHA section. Most of all, I am an experienced writer of technical EHS and public health reports.
