Pros
Some of the pros are pretty particular--for instance my boss is wonderful, I get to telework, and I really enjoy my coworkers. But outside of that you find that there are many more general company attributes that are amazing. Firstly, recognition--we've been in the Washington Tech Fast 50, Inc 500, and also gotten the DoD's Nunn-Perry award. Management also made a really smart decision to partner with TASC in the DoD Mentor/Protegee program, which let the company (which is small) get some really interesting opportunities. Business outlook is really solid, and as an employee that makes me feel good about my future here. Management is also really involved and engaged, and the entire staff are really committed to excellence. Great place to work.
Cons
Ahhh, these reviews have a twenty word minimum for this section. I can't think of any cons at the moment, it is a great company.
