Meet The Team!


Summit Environmental Contractors was founded with the goal of providing environmental-based solutions for all aspects of construction infrastructure projects. Using advanced modeling and statistical technology, we quantify environmental issues in advance of construction!

Environmental pollution can be detrimental to infrastructure modernization and may cause project delays and health hazards. We believe the nation’s current infrastructure is outdated.

It needs to be modernized to provide for a more sustainable and healthier environment for the future.
