Sienna Environmental Technologies was founded in 2000 by Susanne M. Kelley as an environmental consulting firm and laboratory to service the Architectural, Engineering, Construction and General industries.

With locations in Buffalo and Seneca Falls and a multi-disciplined staff, we have completed award-winning projects and a full spectrum of environmental, health and safety consulting services for existing and new construction projects. Our mission is to provide a safe and healthy environment for building inhabitants, and the lands the structures are built upon. Our expert staff identifies contaminants in the air, water, soil and building materials. Working together with the client, we will then recommend remedial solutions to make the building or site a healthy, inviting space to use.
