Pros

Working at Calpine has been phenomenal! From the management to the operations team, everyone has been so friendly and teaching. Personally Mr. Richard Davis has been a charm! He has been by far the best manager I have ever worked with in the last 15 years. He makes sure everyone is taken care of and up to date with what’s going on. Frank himself has been very proactive with us making sure we understand what it is that we do. He’s so kind and I can tell that this experience is going to be just great.

Cons

I have yet to find any cons.
