About ERG

Message from David Meyers

ERG Founder and CEO

David Meyers

In founding ERG, I sought to create an atmosphere of respect, a company where everyone at all levels would be treated with kindness and compassion, and where we could all work collaboratively to serve our clients and do work we believe in. With each year, I'm more convinced that ERG’s commitment to these goals is what makes our success possible.

How does this work? Whether hiring staff or, in a few cases acquiring other companies, we look for people with similar goals, skills, and dedication to client service. We look for people who embrace our collaborative, inclusive philosophy, and who are committed to doing excellent, socially beneficial work. In this atmosphere, our employees develop, grow, and diversify their skills by participating on project teams comprised of different specialties and strengths to meet specific client needs. As a result, we have exceptional employee and client retention and maintain a respectful corporate culture. In annual anonymous staff surveys, 95 percent of respondents agree that “employees interact respectfully” at ERG, with just 1 to 2 percent disagreeing.

The atmosphere of respect that we apply internally extends in equal measure to client relationships. We listen to and learn about our clients’ goals. We work collaboratively with our clients to develop and implement practical, cost-effective plans to meet those goals. And we make ourselves available and responsive to their changing needs and priorities.

I and other senior ERG staff contact our clients regularly to assess our performance. Over the years, their feedback has been nothing short of phenomenal. You might be interested in what they have to say about us:

“ERG is absolutely the best consulting firm to work with.”

“Of all the companies I've worked with in the federal government, you're the most professional and knowledgeable.”

“I am so impressed with your attention to detail, flexibility, imagination, and the professionalism your folks have demonstrated…The personalities and uniqueness that your employees bring to the table deserve recognition and praise.”

Diversity, Equity, and Inclusion

ERG values diversity and continually strives to provide a work environment where every employee feels welcomed and supported as their authentic self. Our corporate DEI policy, “to continuously advance diversity, equity, and inclusion in who we are and what we do at ERG,” is supported throughout the company and implemented by our DEI committee. The committee develops and implements recommendations in three areas:

  • Recruiting, hiring, and retention strategies to increase the number of employees from historically underrepresented populations.
  • Internal training, tools, and resources to promote awareness about the full range of diversity at ERG and best practices to help make our workplace as inclusive as possible.
  • DEI-aware work practices to ensure that our products and services are as meaningful as possible to the full diversity of our clients, partners, and audiences.

Our DEI committee is open to all employees. We encourage job applicants to ask us more about the committee’s work and new employees to join the committee if they would like to do so. We thank our committee for helping us continually improve DEI at ERG.


Small Business and Supplier Diversity Program

ERG is dedicated to fostering diversity, equity, and inclusion in every aspect of our business. Our suppliers are no exception. We recognize that our small business partners are an integral source of experience, innovation, and expertise, and we value and respect the significant economic and social benefits that emerge from utilizing and collaborating with a diverse team of small business subcontractors.

ERG’s dedicated Small Business Liaison Officer advocates for small businesses by conducting outreach, promoting company program initiatives, investigating subcontracting opportunities, networking with small businesses, and fulfilling compliance requirements. We are committed to providing maximum practicable procurement opportunities to small, small disadvantaged, woman-owned, historically underutilized business zone, veteran-owned, and service-disabled veteran-owned small businesses. In addition, we identify and team with state-certified minority-owned and woman-owned businesses, AbilityOne Companies, and Historically Black Colleges and Universities/Minority Institutes whenever possible.

In 2019, ERG proudly accepted the Administrator’s Award for Outstanding Accomplishments by a Large Prime Contractor from the U.S. Environmental Protection Agency. This award recognized our small business program accomplishments, including small business utilization and outreach activities. ERG’s unwavering resolve to advocate for diversity, equity, and inclusion, both within and beyond our organization, is firmly grounded in our policies, allocation of resources, executive leadership, and commitment to our small business and supplier diversity program.

Greening ERG

Climate Goals and Reporting

We are committed to doing our part to help mitigate the impacts of climate change and reduce our carbon footprint. Our climate goals include:

  • Annually conducting a greenhouse gas inventory that accounts for our scope 1, scope 2, and scope 3 (business travel) emissions. See our inventory at The Climate Registry.
  • Using 100 percent renewable electricity to power our corporate offices and laboratories.
  • Balancing any remaining emissions associated with our business operations with high-quality carbon offsets.

ERG is a member of The Climate Registry and has achieved Climate Registered™ Gold level for its increasing ambition in the areas of GHG reporting and reductions.

Renewable Electricity

Since 2003, ERG has purchased renewable energy certificates (RECs) to match 100 percent of our electricity use. For 2022, ERG purchased 2.2 million kilowatt-hours of RECs from ACT Commodities, equivalent to the annual power needs of more than 200 average American homes. The RECs are certified by Green-e and sourced from Buckeye Wind Farm in Kansas.

ERG is a longstanding Partner in the U.S. EPA’s Green Power Partnership, a voluntary leadership program of organizations committed to using green power. Our Partner Profile details our involvement in the program and history of green power use.

Carbon Offsets

ERG purchases high-quality carbon offsets to cover all scope 1 and scope 2 emissions, as well as scope 3 business travel emissions. We partnered with ACT Commodities to balance our 2022 emissions. The offsets are sourced from Gaziantep Landfill Gas to Energy Project in Turkey. The project involves the collection and utilization of LFG to generate electricity. Prior to the project, municipal waste was deposited and left to decay at the landfill sites, releasing large amounts of methane into the atmosphere. The project is certified under the Gold Standard for the Global Goals.

Green Buildings

Our Arlington, Virginia, office is located in a green building, certified by the U.S. Green Building Council through its Leadership in Energy and Environmental Design program at the “silver” level. In a recent renovation, our Chantilly, Virginia, office followed the criteria for many of the LEED credits to green the space.

Accreditations

Quality Management – ISO 9001:2015

ERG achieved ISO 9001 Quality Management System certification from NSF International Strategic Registrations. ERG’s quality management system certification applies to the management of professional, engineering, and IT services that ERG provides under U.S. Environmental Protection Agency (EPA) contracts that require contract-specific quality management plans.

The International Organization for Standardization’s ISO 9001 standard is based on quality management principles such as a strong customer focus, the involvement of top management, and continual improvement. The standard helps organizations reliably meet the needs of clients in both the delivery and continuous improvement of products and services. The standard focuses on performance through a combination of risk-based thinking and a process approach, as well as employment of the “plan-do-check-act” cycle at all levels in the organization.

IT Service Management – ISO/IEC 20000-1:2018

ERG achieved ISO/IEC 20000-1 Service Management System certification from NSF International Strategic Registrations. ERG’s service management system applies to the management of website and IT application help desk services for contracted customers.

The International Organization for Standardization’s ISO/IEC 20000-1 standard helps identify and respond to customer needs through planning, delivery, and improvement of customer services. Implementation of a service management system demonstrates ERG’s commitment to excellence and best practices in service.

Information Security Management – ISO/IEC 27001: 2013

ERG achieved ISO/IEC 27001 Information Security Management System certification from NSF International Strategic Registrations. This certification covers the information security management system ERG established to manage the secure cloud-based environment we use to host corporate and customer-based applications. This environment provides isolated development and staging areas that support software development and testing activities.

The International Organization for Standardization’s ISO/IEC 27001 standard describes the requirements for establishing, implementing, operating, monitoring, reviewing, maintaining, and improving a documented information security management system. The standard focuses on the management and protection of information assets through risk-based thinking, monitoring and measuring controls, and continual improvement.

Capability Maturity Model Integration for Development (CMMI-DEV)

ERG’s Digital and Information Solutions Group was appraised at CMMI-DEV maturity level 3 by JFR Consulting.

Capability Maturity Model Integration (CMMI) is a process and behavioral model that helps organizations streamline process improvement and encourage productive, efficient behaviors that decrease risks in software and service development. CMMI is the result of more than 20 years of ongoing work at Carnegie Mellon University by members of industry, government, and ISACA.

An appraisal at maturity level 3 indicates the organization is performing at a “defined” level. At this level, ERG’s Digital and Information Solutions Group ensures that:

  • We use organizational standards and tailoring to address project and work characteristics.
  • We focus on achieving both project and organizational performance objectives.
  • We’re dedicated to continuous performance improvement and producing the highest quality of products and services.
