Pros
If you're working with the right person, if it's the right fit, and your branch is profitable, you've got pretty great job security. There's a good variety of tasks, so you don't get bored, and it's generally very rewarding to develop relationships with clients. The company is finally recognizing the importance of the branch team (as opposed to just focusing on the FA), and is tailoring more training to the team. The compensation is so-so, but the benefits are quite good, especially the profit-sharing and limited partnership. The corporate culture is unique and supportive.
Cons
As noted, the compensation is underwhelming, and there are limited career advancement opportunities for BOAs once you've made Sr. BOA. The biggest challenge is finding an FA with whom you're well-matched. I've seen many FA/BOA relationships turn toxic when their personalities just didn't mesh. The FAs get minimal training on how to manage their BOA, which contributes to the problem.
