A minority, woman-owned business, IEM was founded by current President and CEO Ms. Madhu Beriwal in February of 1985, and was one of the first companies in the world to focus exclusively on emergency management. Through previous work in hurricane preparedness and floodplain management, Ms. Beriwal saw that most emergency preparedness activities were focused on compliance with accepted standards based primarily on conventional wisdom. She recognized a distinct need to integrate science and objectivity into decisions about public protection.

In forming IEM, Ms. Beriwal’s vision was to revolutionize emergency preparedness by moving it from a subjective foundation to one based on quantitative data. Using this data, emergency managers and public officials can be more confident that response plans and strategies will work—that they will save more lives.

That vision of more than 30 years ago built the company that today is helping government agencies and the private sector save lives. In addition to improving disaster preparedness, response, and recovery, we offer a range of services and solutions that strengthen homeland defense, counterterrorism, and public agency performance. We are extremely proud that because of our success, Ms. Beriwal was inducted in 2012 into the International Women in Homeland Security and Emergency Management Hall of Fame.

IEM is relied on by those charged with ensuring the safety, security, and resiliency of citizens, soldiers, communities, regions, states, infrastructure, and nations. We have worked with federal agencies like the Department of Homeland Security and the Department of Defense; state and local emergency management organizations in all 50 U.S. states, the District of Columbia, and three U.S. territories; critical infrastructure including nuclear power plants, chemical plants, hospitals, mass transit agencies, and ports. Our international work includes projects in India, Russia, Turkey, the Ukraine, Korea, Taiwan, Haiti, and Kuwait.

We have created science-based tools and strategies like those that helped the Federal Emergency Management Agency (FEMA) and the U.S. Army’s Chemical Stockpile Emergency Preparedness Program (CSEPP) to be recognized as one of the most successful risk-based preparedness programs in existence. Working with the State of Louisiana, we helped write that state’s successful $1.4 billion post-Katrina hazard mitigation grant—the largest grant of its kind. We have supported disaster recovery programs for every major disaster since Hurricane Katrina, including Superstorm Sandy in 2012. We have created scenario-based workshops that drive planning for catastrophic disasters, web-based emergency management decision support systems, models that determine the effectiveness of bioterrorism preparedness strategies, and frameworks for combating terrorism in the 21st century.
