Founded in 1997, The Sapphire Group set out to structure a business that provided solutions, not just data, to businesses that manufacture, transport and use chemicals and chemical products.  

Today, The Sapphire Group is a leading international health science integrated risk management firm that provides innovative approaches and sound science to risk-based decision-making and advocacy.  

Dr. Robert G. Tardiff is one of the founding principals and is currently serving as CEO and Senior Managing Principal. Previously, Dr. Tardiff served as Chief of the Toxicological Assessment Branch of the U.S. EPA, and as Executive Director of the National Academy of Sciences/National Research Council Board on Toxicology and Environmental Health Hazards.

Cofounder, Richard P. Hubner, M.P.H., President of The Sapphire Group, provides complementary expertise as a public health and occupational health professional, giving The Sapphire Group a solid foundation of services for their clients. Mr. Hubner's background comprises considerable knowledge in health assessment and exposure analysis, industrial hygiene, and science advocacy.  

Essential to the enterprise's success is its global presence. Heading up the European operation, John Fawell has led numerous toxicological research programs on drinking water contaminants and acts as technical advisor to a European science team developing environmental standards. Additionally, Mr. Fawell is actively involved with key entities of the European Union and vital institutions such as the World Health Organization.
