Pros
The ability to experience and contribute to a wide variety of environmental projects. The company is deeply rooted in client service and response work. Doing a lot of emergency response work in my 4 year tenure, I was able to experience and learn things that most consultants won't see in their entire career.
Family owned, and they are truly invested in their employees and families.
This is a company that rewards hard work & dedication.
Cons
They do the best they can with benefits, but don't have the bargaining power of a 5000 employee firm.
