About Us

Gordon & Rosenblatt is a consulting firm founded by Gilbert Gordon and Aaron Rosenblatt in 2009. Our mission is to protect people by preventing Legionnaires’ disease and other facility-associated waterborne diseases, including infections by non-tuberculous mycobacteria (NTM) and Pseudomonas.

We are our clients’ advisors and advocates. Our work is informed by our practical experience, our understanding of waterborne disease and our working knowledge of the rules, regulations and standards that cover building water systems. Our clients include hospitals, nursing homes, hotels, multi-unit residential communities, water parks and office buildings. In 2021, we became the water management consulting services partner of WW Grainger.
