Gaithersburg, MD – Therrien Waddell and The GreenBench Companies are proud to announce a new partnership whereby GreenBench has acquired a minority interest in Therrien Waddell. The companies will remain separate and will continue to operate independently. Current service offerings and active contracts will remain unchanged.

This partnership enables both firms to broaden their perspectives and understanding of the construction industry's issues with a coordinated focus on the adoption of best practices in the areas of leadership and training, communication, risk identification and mitigation, and the integration of technology.

Leveraging their collective expertise allows each firm to improve their overall service offerings, deliver a strong client experience, and, in the right circumstances, offer a comprehensive client journey from development and planning through construction and closeout activities.

‘This partnership is a natural extension of our 15-year relationship with the leadership of GreenBench,’ says Matt Maynard, Therrien Waddell's Principal. ‘We look forward to the opportunities ahead.’ While each firm will continue to offer competitive services individually, the two teams can now offer a broader and more robust list of services in those situations when they are working together. ‘Relationships are at the core of everything we do, and in that way, GreenBench and Therrien Waddell have always been aligned,’ recalls Principal Dave Wagner of The GreenBench Companies. ‘We believe this partnership will make GreenBench better, which will serve to strengthen our relationships with our clients and other general contractors on future projects.’
