Birth of a purpose-driven company
In 1969 Clarence “Lucky” Lester and three U.S. Department of Defense analysts founded the Inner City Fund to finance minority-owned businesses in Washington D.C.

Our first president was Clarence “Lucky” Lester, a member of the Tuskegee Airmen in World War II. He earned his nickname after flying more than 90 missions without being hit. He also downed three enemy aircraft in less than six minutes. Outside the military, “Lucky” was known as “Les” by friends and family. He was a passionate photographer and had an affinity for fast cars.

After the war Lucky partnered with Donald “Don” Ogilvie, Herbert S. “Pug” Winokur Jr., and Bruce Caputo — who knew one another from business school and from working at the Pentagon — to establish the Inner City Fund. Our founders, who did not take any outside funding to start the company, sought to finance minority-owned businesses in the nation’s capital. In 1972 we transitioned our focus to consulting, changed our name to ICF Incorporated, and became a well-respected advisor to a number of U.S. federal agencies.

Some of our early clients included the National Security Council, the Office of Child Development, the National Academy of Sciences, the Federal Maritime Association, and the District of Columbia Public Schools system. By the mid-1970s, our founders were less involved in the business, pursuing other passions and career ventures. They had no idea how big ICF would become.

1972
Shifted from venture capital focus to professional services and renamed ICF Incorporated.

Emergence of a consulting leader
We quickly grew as a consulting firm, becoming a trusted partner in policy and strategy in areas including energy, environment, health care, and economic development.

During the 1970s U.S. federal agencies ramped up their regulatory activity — including at the newly created Environmental Protection Agency (EPA), established in 1970, and the Department of Energy (DoE) which was established in 1977. We partnered with these agencies early on to help drive results in energy, climate, and the environment. Other clients included the U.S. Department of Health, Education and Welfare; the U.S. Department of Labor; the U.S. Department of Transportation; the United States Agency for International Development (USAID); and The White House. While U.S. federal, state, and local governments comprised most of our client base during these years, we performed about 10 percent of our work for the private sector.

In the late 1970s and early 1980s we took on more ambitious projects as our expertise and capabilities grew. Notable work included environmental and risk assessments for the EPA that led to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980. Informally called Superfund, CERCLA gives EPA the funds and authority to clean up contaminated sites that pose risks to human health and the environment.

In 1984 we won a project to help USAID implement the Demographic and Health Surveys (DHS) Program (initially as Macro International, Inc., later acquired by ICF), our longest-held continuous contract. Over the last 35 years we have collected, analyzed, and disseminated critical data on important health topics such as fertility, family planning, maternal and child health, gender and domestic violence, HIV/AIDS, malaria, nutrition, and environmental health. Health and government officials use the survey data to make important decisions to improve the overall health and economic status of populations in developing countries.

We continued to pursue meaningful work, which led to two more high-profile projects in 1984. First, in partnership with the U.S. Department of Labor, we estimated the economic loss to Japanese Americans interned during World War II as part of a congressional commission. Additionally, in conjunction with the EPA, we published the groundbreaking book Greenhouse Effect and Sea Level Rise: A Challenge for this Generation, which was decades ahead of its time in its investigation of the potentially catastrophic implications of the “greenhouse effect” and the impact of global warming on sea levels.

Tackling complex energy, health, and environment challenges
In the late 1980s and early 1990s we continued to grow our consulting business, partnering with clients on complex energy, environment, health, and socioeconomic development issues.

We expanded our energy portfolio (and our team) in the 1980s and 1990s, performing exciting work for the U.S. government and the private sector. We outgrew our offices in downtown Washington, D.C. and relocated to our existing headquarters in Fairfax, Virginia, just outside the nation’s capital, in 1987. We continued to accelerate our climate, energy, and environment work while expanding our portfolio in health and human services in the public sector. During this time we also began to build on our advisory services with program management and implementation work that grew rapidly throughout the decade.

In 1987 we developed the first Integrated Planning Model (IPM) of the North American power, fuels, and environmental markets. The federal government used IPM to help craft the U.S. Clean Air Act Amendments which established a program to phase out the use of chemicals that deplete the ozone layer. Also in 1987 we helped implement The Montreal Protocol on Substances That Deplete the Ozone Layer, a global agreement across all United Nations (UN) members to protect the stratospheric ozone layer by ending the production and use of ozone-depleting substances. Two years later we worked with the EPA to create the first-ever U.S. national greenhouse gas (GHG) inventory to help inform climate change policy, an index that we continue to compile today.

In 1988 we acquired Kaiser Engineers. This allowed us to provide implementation support — primarily for large engineering and construction projects — associated with our existing work in energy and environment. A new company called ICF Kaiser was formed and ICF Consulting became one of three divisions within it, the other two being engineering-related.

But it wasn’t all about climate and energy; we also expanded our scope in health and human services during this time. In 1990 ICF began operating and managing the Child Welfare Information Gateway (initially as Caliber Associates, later acquired by ICF), an online library with hundreds of thousands of resources dedicated to protecting children and strengthening families. In 1990 we also implemented The Behavioral Risk Factor Surveillance System (BRFSS) (initially as Macro International, Inc., later acquired by ICF), a powerful tool for targeting and building health promotion activities across the nation, on behalf of the Centers for Disease Control (CDC).

Implementation work fuels growth
In the 1990s and early 2000s, we expanded our consulting services to include program implementation, powering industry-changing projects like ENERGY STAR and Head Start.

Following the launch of projects like the greenhouse gas inventory in the prior decade, U.S. federal agencies like the Environmental Protection Agency (EPA) and the Department of Energy expressed interest in energy-efficient products and offerings. For ICF this meant more work in commercial energy. In 1992 we worked with the EPA to launch the ENERGY STAR program, which helps customers save money and protect the climate by purchasing highly energy-efficient products and services. Since 1992 ENERGY STAR and its partners have helped American families and businesses save nearly 4 trillion kilowatt-hours of electricity and achieve more than 3 billion metric tons of greenhouse gas reductions. This is equivalent to taking more than 600 million cars off the road for a year – more than twice as many as were on U.S. roads in 2018! We continue to support the ENERGY STAR program while working with utilities across the U.S. to plan and manage energy efficiency programs.

In 1996 we began an ongoing partnership with the U.S. Army Research Lab (ARL) (initially as Jacob & Sundstrom, Inc., later acquired by ICF), greatly expanding our cybersecurity capabilities. We collaborated with ARL to research, test, and apply new technologies to support U.S. national defense. In 1999 we implemented The National Adult Tobacco Survey (NATS) (initially as Macro International, Inc., later acquired by ICF), the first nationwide adult tobacco survey in the U.S., on behalf of the Centers for Disease Control and Prevention (CDC). One year later, we worked with the CDC to deploy the National Program of Cancer Registries, Cancer Surveillance System (NPCR-CSS) (initially as Macro International, Inc., later acquired by ICF), one of the agency’s largest disease surveillance systems, to help policymakers and researchers make timely and informed decisions regarding patient care.

While the consulting part of our business continued to thrive, the two engineering divisions within ICF Kaiser struggled. In June of 1999 the consulting management team led a leveraged buyout of the consulting arm, in partnership with CM equity, splitting from ICF Kaiser. Some 35 senior managers supported the transaction with their own financial contributions. We returned to being a privately-held consulting company, and Sudhakar Kesavan was named CEO. This enabled us to control our own destiny and focus on growing our core consulting business.

Four years later, in 2003, we started a relationship with the Office of Head Start (initially as Caliber Associates, later acquired by ICF), that continues today. For more than 15 years we have worked together to manage the Head Start program that helps the nation’s most at-risk populations achieve the highest-possible performance in school readiness, child welfare, family engagement, professional development, and community support. Services include language and literacy learning, healthy meals, and financial planning. Head Start today supports roughly 1 million people, including children under the age five and expectant mothers.

Expansion and America’s largest housing recovery effort
During the early 2000s we continued to grow. And in 2006 we launched America’s largest housing recovery effort.

The 2000s were a time of rapid growth for us. Following the leveraged buyout of 1999 we acquired several companies to add subject matter expertise and implementation skills to our offerings. We acquired two divisions of Arthur D. Little (2002) strengthening our environment, energy, applied technology and program management capabilities. In 2005 we acquired Synergy, Inc., enabling ICF to provide mission-critical and technology-based solutions for the U.S. Department of Defense and other federal and state agencies. Also in 2005 we acquired Caliber Associates, enhancing our IT and workforce offerings for the U.S. Defense, Education, Health and Human Services and Justice departments.

In 2005 the most active Atlantic hurricane season in recorded history saw catastrophic damage to the southeastern U.S., particularly from Category 5 Hurricanes Katrina and Rita. These storms, among the top 10 most intense Atlantic storms in history, battered U.S. states Florida and Louisiana just one month apart. Nearly 4,000 lives were lost, and damages totaled over $180 billion. In the aftermath of Hurricanes Katrina and Rita, we partnered with the State of Louisiana to implement Road Home, the state’s Community Development Block Grant - Disaster Recovery (CDBG-DR) program. CDBG is one of the largest continuously run programs at the U.S. Department of Housing and Urban Development (HUD). The Road Home, a joint effort with several partners and federal agencies, including the Federal Emergency Management Agency (FEMA), was an ambitious and complex project that would eventually become the largest single housing recovery effort in U.S. history.

Despite massive infrastructure challenges and the complexity inherent in such a vast, unprecedented project, we opened nine housing assistance centers within 90 days of being contracted. We later added four more assistance centers and a mobile center to handle the high demand for assistance. We also hired 2,300 intake staff to augment state, local, and nonprofit capacity. We ensured that there was no duplication of benefits and that funds were tracked to the individual case or applicant level, a critical step for protecting taxpayer investment in federal and state programs. As of 2018, the Road Home program had dispersed more than $9 billion dollars to over 130,000 Louisiana residents affected by Hurricanes Katrina and Rita.

2006
Managed the Road Home program to assist citizens in rebuilding after Hurricanes Katrina and Rita.

Going public: expanded capabilities, global reach
ICF went public on NASDAQ in 2006 following tremendous expansion of our core offerings. This led to a series of acquisitions and continued growth.

Our organic and acquisitive growth during the period from 1999 to 2006 allowed us to do something big: we went public on NASDAQ with the stock ticker ICFI on September 28, 2006, having raised $56M. That same year, compelled by our corporate commitment to environmental stewardship, ICF employees pushed the company to take more responsibility for our carbon footprint. We became the first professional services firm in the world to achieve net carbon neutrality by purchasing high-quality carbon offsets.

From 2007 to 2009 we quickly grew through a series of strategic acquisitions including: Energy and Environmental Analysis (EEA) (2007), enhancing our capabilities in alternative fuels such as natural gas, and in automotive emissions and fuel efficiency technologies that impact greenhouse gas emissions; Advanced Performance Consulting Group (APCG) (2007), broadening our capabilities in federal organizational performance, human capital, and strategic communications consulting; Z-Tech Corporation (2007), which brought additional health technology skills; Simat, Hilliesen & Eichner (SH&E) (2007), which added aviation consulting capabilities; Jones & Stokes (2008), which expanded our geographic presence to the West Coast and greatly enhanced our environmental expertise; Macro International, Inc. (2009), which significantly increased our public health and international health portfolio; and Jacob & Sundstrom, Inc. (2009) which brought cybersecurity and identity management.

At the same time we continued to grow organically, largely due to The White House’s significant investment in the economy following the financial crisis. We supported key infrastructure and implementation projects that were funded under the American Recovery and Reconstruction Act (ARRA). We worked with the Department of Agriculture to encourage the installation of broadband access to underserved and rural communities; with the Department of Education to support the Race to the Top program; and with the Centers for Disease Control and Prevention (CDC) to reduce the risk factors for chronic diseases. ICF’s organic growth in its federal business during this period was well above 10 percent.

We also experienced robust double-digit growth in our commercial energy efficiency business during this period. This was driven by more than 30 state public utility commissions mandating the implementation of energy efficiency programs by utilities and providing a dedicated funding stream to support such programs, typically through a small public goods charge on energy bills. In 2008 we were selected to work with the Baltimore Gas and Electric Company (BGE), an Exelon Corporation company, to pioneer one of the first, longest-running energy efficiency programs in the nation. Since 2008 we have assisted utility clients in more than 30 states to design and implement innovative energy efficiency programs that help their customers save energy and money, while helping the states and utilities achieve efficiency targets and improve grid resiliency and reliability.

We also expanded our geographic presence. In 2011 we acquired Canadian-based Marbek Resource Consultants Ltd, strengthening our position in energy efficiency, renewable energy, and pollution prevention programs. Also in 2011 we acquired Ironworks Consulting, L.L.C. which accelerated our technology implementation skills and was the first step in building what would eventually become a powerful commercial marketing technology services capability. A year later in 2012, we acquired London-based company GHK Holdings Limited, strengthening our advisory services capability in the U.K. and Europe. That same year, we purchased the Sustainability Information Management System (SIMS) platform, an analytical framework used by energy utilities to make informed decisions on resource consumption trends and program effectiveness.

In the midst of this growth we grew our disaster recovery and management offerings. In 2011 we helped launch the HUD Exchange, an award-winning online platform that provides program information, guidance, services, and tools to the U.S. Department of Housing and Urban Development’s (HUD) community partners to help build resilience before a disaster hits. In 2013 we expanded our work in disaster recovery, helping more than 30,000 people in the Northeast U.S. return to their homes or relocate to safer areas following the damage caused by Superstorm Sandy.

Over the last few years we’ve continued to expand our work in Europe. In 2013 we partnered with the U.K. Department of Business, Energy and Industry Strategy (BEIS) on the Energy Using Products Programme, building on our ENERGY STAR work. To this day, we provide technical and economic analysis services to the U.K. government, influencing European Union (EU) regulations on mandatory Minimum Energy Performance Standards (MEPS) and energy labels for domestic products including appliances, lighting, and other devices. We also manage applications and assessment criteria for a U.K. incentive program to encourage industrial and commercial consumers to purchase highly energy-efficient products. We replaced a 16-year incumbent on the project and established ICF as a recognized program contractor for the U.K. government. Since that win we have expanded our services to BEIS and now deliver support for the Energy Technologies List and the Industrial Heat Recovery Support Programme (IHRS), a GBP 18 million grant programme to support feasibility studies, detailed engineering and capital expenditure analysis on IHR projects in the U.K.

Starting in 2015 we worked with the EU Network of Public Employment Servies (PES) to establish a formal and highly engaging mutual learning program that connects jobseekers with employers to help reduce the soaring levels of unemployment across the EU. Beginning in 2016 we won another impactful project for the EU: the EU Aid Volunteers programme, a lighthouse project that trains young volunteers for humanitarian aid. Also in 2016 we started working with the European Commission to strengthen relationships with North America and China on sustainable urban development, climate change, and cooperation on energy programs.

In 2017 we again expanded our disaster recovery work with the launch of projects in Texas and Puerto Rico. These projects are focused on helping residents and communities recover in the aftermath of Hurricanes Harvey, one of the most costly and damaging storms on record and Maria, the most powerful and devastating storm to ever hit the island of Puerto Rico. In addition to case and project management, we are also bringing new innovation to recovery efforts. In Puerto Rico, we are partnering with the Federal Emergency Management Agency (FEMA) to leverage innovative technologies including drones and 3D modeling to quickly assess damage and expedite access to federal recovery funds. In 2018 we acquired DMS Disaster Consultants, which now operates as part of our disaster management and resilience division.

For decades ICF has delivered strategic communications services to U.S. government clients. As the state of the art in commercial marketing technology advanced, ICF moved to expand our market access in this newly emerging space, as well as to bring these cutting-edge, commercially derived skills to our existing client sets. The 2011 acquisition of Ironworks was the beginning of this effort, followed by the 2014 acquisitions of CityTech and Olson, which together greatly increased our service to commercial sector customers in marketing, communications, and marketing technology. In 2014 we also acquired Mostra SA, a leader in strategic communications for the European Commission. We followed that by acquiring The Future Customer in 2017 and We Are Vista in 2018, both marketing firms based in the U.K. serving the private sector. In the midst of acquiring organizations that expanded our marketing and communications capabilities, we acquired ECA, a boutique ecommerce solutions provider, in 2013.

In 2019 we launched ICF Next, encompassing all of our marketing, communications, and technology organizations to bring our outreach and engagement capabilities to private and public sector clients worldwide. ICF Next represents an exciting period in our evolution, enhancing our ability to bring our complete set of capabilities to clients in the energy, financial, consumer, government, health, and travel and hospitality industries. For example, we worked with the Belize Tourism Board (initially as Olson, later acquired by ICF), to create a 95 percent year-over-year increase in tourism growth; we serve three of the largest global hoteliers to provide loyalty marketing services; and we partnered with the CDC to launch the Be Antibiotics Aware campaign to promote appropriate antibiotic prescribing and use. We also supported the CDC on RxAwareness to help combat the nationwide opioid epidemic. And we helped the European Union engage its citizens on policy issues (initially as Mostra SA, later acquired by ICF).
