Pros

This is a great company to work for... The managers that I work with has been very supportive. They actually give compliments. As a new hire, there was always someone that was willing to assist me in navigating my way through the company. The business unit had undergone some significant changes prior to me. In reading some of the reviews, I was skeptical but this was the best decision I could have made. Reviews are written from the persons perspective and it does not mean, another person will have the same experience- I didn't. I am glad to be apart of the team. The benefits are decent

Cons

Every job has a downside, you just have to make the best of it. This place is much better than my last employer so I have no complaints

Pros

Tetra Tech has some great staff members, but the management is terrible.

Cons

The company is 100 small acquisitions that each operates as a separate entity. This creates a lot of confusion and it prevents sharing of knowledge and expertise across the company. Working there is similar to working at a small regional firm except your clients expect big firm capabilities.
