Geosyntec Consultants has acquired Longenecker & Associates, Inc. for an undisclosed amount. Longenecker & Associates, Inc. (L&A) is a small, woman-owned business recognized for providing highly specialized, fast-response technical and management support to the nuclear and environmental industries. Its team comprises senior management and technical specialists, delivering a broad base of expertise to clients across both the private and public sectors.

Geosyntec Consultants is a leading consulting and engineering firm known for its work in environmental, infrastructure, and energy projects. This acquisition strategically enhances Geosyntec’s capabilities, particularly in the highly specialized nuclear and complex environmental sectors. The addition of L&A’s experienced personnel and their proven model for delivering rapid, expert support is expected to expand Geosyntec's service offerings and deepen its technical bench in critical areas.

The integration of L&A into Geosyntec is anticipated to create significant synergies. Geosyntec will gain L&A's established expertise and client relationships in the nuclear and high-level environmental management fields, allowing for a more comprehensive service portfolio. Conversely, L&A’s specialized services will benefit from Geosyntec’s broader platform and extensive resources, enabling the combined entity to pursue larger and more complex projects requiring diverse skill sets.

This corporate acquisition aims to strengthen Geosyntec’s market position as a provider of high-value, specialized consulting services. The combined entity is expected to deliver enhanced technical and management solutions to a wider array of clients, particularly those facing complex challenges in the environmental and nuclear energy sectors, driving future growth and expanding its strategic impact.
