Pros
10% 401 matching, lots opportunities, and very friendly supportive-communicative and dependable staff. I was between contracts. I was waiting a long time for a new contract to start up (I was working tutoring my son with his college courses while waiting for a unique opportunity to start up) and Legato LLC put pressure on PRIME to bring me on earlier! And PRIME brought me in 2 months early.
Cons
Honestly can't think of any!
