OnSite-LLC is a collaborative team of scientists, engineers and medical professionals with extensive, collective experience in Planning and Design of healthcare's built environment, Infection Prevention and the role of the microbiome in the Environment of Care. Together, we are uniquely qualified to conduct and use research based evidence to help facilities optimize their patient spaces by using fewer resources to create cleaner environments.

“With every increasing fiscal constraint, our leadership recognizes the need to determine business cases for optimization of our environments. OnSite-LLC provided a facilities functional performance assessment of our systems to help us obtain the necessary capital to improve them. It was truly a miracle for us.”
— Facilities Director Academic Medical Center
Our organization used OnSite-LLC to measure the efficacy of our invention through third party independent testing. When we saw their EQI Methodology for measuring dynamic environments in the operating room was published by the American Journal of Infection Control, we knew it was exactly what we were looking for to validate our product.
