Our Company

In 1992, Neptune and Company, Inc. (Neptune) was founded with a simple mission: to improve the quality of environmental decision making through the application of state-of-the-art methods in quality assurance, data science, and risk assessment. As a small, employee-owned business, our vision was to work with risk managers to solve difficult problems that require the courage to innovate, the willingness to collaborate, and the expertise to succeed. We recognized that decision makers need partners that they can rely on to produce practical, defensible, cost-effective solutions to technical problems. Today, Neptune remains dedicated to this vision even as our mission and capabilities evolve in response to increasingly difficult decision problems at the nexus of energy, environment, health, food, and climate change. 


Neptune employs a multi-disciplinary staff of over forty-five statisticians/data scientists, decision analysts, mathematical modelers, risk analysts, chemists, toxicologists, health scientists, and ecologists. Our IT specialists routinely develop custom software and data management applications to support risk-based decision making. Roughly three-quarters of our staff have advanced degrees and certifications (16 PhDs, 16 masters, DABT, PE), combining a high level of expertise with an average of more than 15 years of relevant professional experience. 


Neptune specializes in (1) statistical analysis and quality assurance of health and environmental data,
(2) characterization of risk to human health and the environment, and (3) development of decision analysis methods/software to facilitate all forms of risk management.
