Pros
The hours aren't as bad as some other public accounting firms. Large presence in Denver so you have some clout when looking for other jobs.
Cons
This is the least professional office I've ever worked at and unfortunately nothing is going to change because some of the worst gossips are the partners. A partner should never gossip with staff or seniors but they will openly badmouth anyone who decides to leave (as if high turnover in public accounting is anything unique) to lower level employees for the entire office to hear. When you do quit they'll try and manipulate you you out of leaving with the most ridiculous lies about how once you leave public accounting your career and compensation will stagnate, and unfortunately people fall for it and don't even realize the culture is toxic because it's their first job out of college.
