Founded in 2016 by Matt Harrison and Asher Weinberg, the firm provides air quality and monitoring, environmental, and natural resources services that help clients permit, operate, and decommission assets.

It serves more than 100 clients, with its top 10 customers averaging more than seven years of tenure.

The founders and delivery leaders built their careers inside the operators Quandary now serves.
