For more than 50 years, we have combined innovation, energy efficiency, and safety to offer a full range of services, including: mechanical, electrical, and structural engineering; plumbing and fire protection design; commissioning; and information technology. We approach each project with an emphasis on sustainability, cost-effectiveness, and quality — an approach that has guided us through thousands of successful projects in the fields of energy, education, healthcare, industry, commerce, and government.

Henneman Engineering has continued to evolve in order to meet our clients’ needs. Today, this includes working with clients to create or renovate structures that are energy efficient, sustainable, and prepared for the challenges of a 21st-century economy. Henneman is honored to be among a handful of American engineering firms granted ISO 9001 certification, a designation that reflects our dedication to excellence at all levels of our work.


Leadership at Henneman Engineering has also evolved with daughters, following their family’s legacy of success, taking ownership. This brings national designation of our firm as a Women’s Business Enterprise (WBE) as certified by WBENC – the Women’s Business Enterprise National Council.
