Pros
The best reasons to work here are that your scope of your responsibilities and roles and your influence on the company are limitless. Those who are self-managers, take initiative, who engage in positive communication, and who aren't afraid to speak up and get involved can make a huge impact on the company, and on their own position in the company. The owners are VERY open to suggestions, and in learning what their employees feel will benefit the company, the customers, and the culture.
Cons
As with all small companies, one challenge is learning to multitask and wear multiple hats without feeling overwhelmed or falling behind. One thing I've learned to do is to be honest with myself and my employers when it comes to how much I'm handling and learning when to say "I need help." It's easy to get caught up in managing your tasks without turning to higher resources for assistance when needed.
