PHE is an innovative environmental, planning, and technology consulting firm. Our engineers, scientists, and planners are engaged in complex programs and projects solving today’s most pressing environmental, climate change, energy, and national security challenges. In our 30+ year history, we have earned a reputation as a provider of responsive, cost-effective, and high-quality services to Federal and private sector clients. PHE leverages staff expertise, a broad network of industry and government partners, and value-adding information technology to consistently produce exceptional results in the following service areas:

• Environmental Analysis, Communication, and Documentation;
• Environmental Compliance, Management, and Sustainability; and
• Site Evaluation, Characterization, and Planning.


Throughout our history, PHE has operated on the basic principle that above all else, we must focus on performing exceptional work for our clients. Consistently striving to meet that goal enables us to structure our organization, our management approach, and our resources effectively. Our founding partners, who had come from large firms that were plagued with bureaucratic challenges, were inspired to create an organization that focused its senior professionals’ time and energies on serving client needs and applying technology to add value to our services. This philosophy has served us well through the years, and today, we are one of the fastest-growing environmental consulting firms in the country. As we have grown from a small business to a mid-size firm, our underlying principles have allowed us to remain nimble with a leadership that is still able to focus on our clients’ needs.

Our corporate mission can best be summarized as:

Be the consultant of choice, be the employer of choice, and provide exceptional hands-on support for challenging environmental, management, and information technology projects and problems.

Living this mission has led to the development of a corporate culture that attracts highly talented professionals, and a working environment in which these professionals can thrive. Our culture (click here to learn more) sparks the dedication and passion needed to execute our clients' most challenging requirements successfully.

PHE’s dedication to our clients and the exceptional services we provide have gained us a reputation as a go-to firm for completing the most complex projects. Whether it is a project with a demanding schedule or challenging technical barriers, the common denominator with PHE is excellent service and value. Our long history of repeat customers is the best reflection of our success of this mission.
