Consulting at the Leading Edge of Science & Technology
Since 1982, ENVIRON has worked with clients around the world to help resolve their most demanding environmental and human health issues. We combine resources across geographic boundaries and technical and scientific disciplines to provide clients with the best, most responsive teams—whether responding to existing challenges, evaluating opportunities to improve performance or seeking to reduce future liabilities. Clients benefit from our unique ability to bring clarity to issues at the intersection of science, business and policy.

The entrepreneurial spark that defined ENVIRON's beginnings remains evident in each innovative, forward-thinking solution we deliver. Advances in science and technology and evolving regulatory, legal and social pressures create increasingly complex challenges for businesses. We evolve to keep pace with these changes—by adding new services, contributing to scientific advances or expanding geographically—all with an eye to supporting our clients' changing needs.


ENVIRON is the premier global consultancy, working with clients to manage their most challenging environmental, health and safety issues and attain their sustainability goals.

We anticipate and keep pace with our clients’ evolving needs by continually enhancing our global geographic presence and broad spectrum of complementary technical and strategic skills.

We uphold the highest ethical standards, support professional activities that provide a public service and maintain a workplace environment that attracts the most talented professionals to our employee-owned firm.

We deliver innovative and responsive solutions based on a clear understanding of a client's needs and objectives; a thorough analysis of technical, regulatory and community considerations; and the application of sound scientific and engineering principles.

We look for opportunities to reduce the environmental effects of our operations, and support activities that promote the protection of human health and a sustainable global environment.

ENVIRON was founded in 1982 in Washington, DC, as a privately held consulting firm providing a broad range of services to clients concerned with the problems of human exposure to potentially hazardous substances in the environment; in food ingredients and packaging; in drugs, medical devices and consumer products; and in the workplace. The strong demand for chemical risk assessment and environmental risk management services that drove the firm's growth in the early years was fueled by the public's insistence that effective steps be taken to manage exposure and health risks related to the products and by-products of industry and technology.

At the outset, the firm chose to pursue a course of planned, measured growth to meet the challenge of geographical expansion without diluting leadership or weakening the company's ability to perform sophisticated multidisciplinary engagements. The first ten years saw expansion to six domestic offices on both US coasts. Subsequent domestic expansion positioned ENVIRON strategically throughout the US.


After an almost 10-year period in the 1990s as a wholly owned subsidiary of publicly traded parent companies, ENVIRON reprivatized with a management buyout in 1999. The privatization of the firm, at a time when many competitors were consolidating and becoming part of larger publicly held corporations, enhanced ENVIRON's ability to attract and retain the best and brightest practitioners that our industry has to offer—those seeking an environment that fosters collaboration, creativity and sophisticated thinking. Our privatization has enhanced the entrepreneurial spirit that was at the heart of ENVIRON from the outset, returning control of the firm to those who provide client services and who hold the successful provision of these services as their highest objective.

The 2003 merger with Applied Epidemiology, Inc. (AEI), brought to ENVIRON a full range of epidemiological consulting services in occupational health, environmental health and injury and disability research. The application of epidemiological concepts and methods provides powerful, data-fueled solutions to a wide array of health risk challenges.

In the spring of 2005, ENVIRON merged with The ADVENT Group, Inc., a premier consulting and engineering organization that specializes in Integrated Industrial Wastewater Management and related areas for predominately industrial clients. This merger created a firm uniquely qualified to provide a full range of engineering and technical services to help clients meet their business goals related to water management.


In August 2007, ENVIRON acquired Boelter Associates, Inc.—the largest single acquisition in the firm's history. The addition of Boelter's seasoned professionals positioned us to offer clients expanded consulting capabilities, particularly in the areas of industrial hygiene and building forensics. The subsequent 2008 acquisition of Chicago-based Gustitus Group, Inc., brought to ENVIRON a well-established core practice in forensic architectural services and additional Leadership in Energy and Environmental Design (LEED)-certified practitioners. These two acquisitions positioned us to offer comprehensive building-related environmental, health, safety and energy-related services to our existing global network of property/real estate sector clients.

We shall continue to add strategically located offices, offer new services and pursue mergers or alliances that will position us to keep pace with the evolving needs of our global client base. The founders' original vision of bringing together the interrelated backgrounds and disciplines necessary to address the complex issues and inherent uncertainty encountered by business decision makers remains at the heart of ENVIRON.


Since its inception over 25 years ago, ENVIRON has advanced practices and technologies that support the corporate responsibility and sustainability initiatives of our clients around the world. We are proud of our continuing contributions to the field and to our clients' responsible stewardship of their operations and assets. We are also proud of our commitment to continually enhancing our own performance as a responsible corporation. Throughout our business, we uphold ENVIRON's Corporate Responsibility Policy (the Policy), which established the following primary objectives:

  • To maintain a workplace environment that attracts the highest-caliber consultants and supports our employees in attaining their professional goals
  • To promote the protection of human health and a sustainable global environment
  • To reduce the environmental footprint of our own operations
  • To support the communities in which we work and live
  • To operate in a manner consistent with the highest standards of business ethics

Adopted by the ENVIRON Board of Directors and implemented by the ENVIRON global Corporate Responsibility Committee in conjunction with firm management, the Policy defines three primary elements of responsibility and specific commitments within each:

  • People
  • Environment
  • Community

The ENVIRON Corporate Responsibility Committee has developed metrics which allow us to monitor our performance in each of these areas. Our performance measures and targets are updated as our experience grows and as our Corporate Responsibility program evolves.


ENVIRON is committed to promoting employee professional development; diversity, inclusion and equal opportunity; workplace safety and health; and responsible business practices with our contractors and suppliers. ENVIRON is committed to upholding the highest standards of business ethics in all our internal and external affairs. As part of this commitment, ENVIRON has also established a Business Ethics Policy and Code of Conduct that applies to all employees. We deliver interactive on-line training for all employees in the various aspects of workplace conduct, such as harassment, to foster awareness and understanding of the roles and responsibilities of all staff members to ensure a workplace environment where all employees are treated with dignity and respect.

ENVIRON recognizes the opportunity to promote the protection of human health and a sustainable environment through our work on behalf of our clients, as well as through our own operations. We are committed to our ongoing efforts to reduce our environmental footprint, and helping our clients do the same, by providing the means to measure and manage our use of energy, water and other consumables.

For example, ENVIRON has achieved the status of 'Climate' by successfully registering its North American greenhouse gas (GHG) emissions inventory according to the rigorous standards of The Climate Registry. Becoming 'Climate Registered' requires the annual calculation, verification and reporting of complete and accurate GHG emissions inventories in a transparent manner for all North American locations. ENVIRON is also proud to have been recognized as a leader in climate change consulting services through inclusion in The Climate Registry's Climate Pages.


ENVIRON encourages employee contributions to our own communities and to the global community by supporting volunteer programs; maintaining initiatives such as ENVIRON's Pro Bono and Disaster Relief programs; and through the work of the ENVIRON Foundation, which has donated more than $1,500,000 to not-for- profit organizations around the world since its inception in 2005.

For example, in 2010, the ENVIRON Foundation and the ENVIRON Pro Bono Program supported Light4Life, a project to bring photovoltaic power to a remote rural school in the Himalayan community of Dhawa, Nepal. This pilot project uses clean, sustainable energy to transform the school building into a self-sustaining educational, cultural and commercial resource. The resulting significant reduction in the school's reliance on kerosene lighting is helping to improve health conditions, reduce fuel costs and local pollution and extend the use of an important community facility by increasing the use and reliability of computers and a projector, units for commercial use and a photo studio, all powered by photovoltaic electricity. Light4Life hopes that the pilot project's success will influence decision makers in other parts of the region, thereby accelerating the transformation to sustainable rural communities. ENVIRON's contribution included a Foundation grant and time volunteered by a member of the UK Carbon and Energy Management team.
