Pros
The AAMC has a great mission and that is focused on improving healthcare for all by ensuring quality education for future and current physicians and medical researchers. They promote from within and are keen to offer educational opportunities for current employees. They frequently seek input from employees about their experiences and are actively working to improve the company culture.
Cons
Unfortunately, for many of the reasons that working for the AAMC might be considered a check in the "Pros" column, it can be very challenging to work there, especially if you are an outsider coming into the organization. Although upper level management is actively working to improve the culture, it isn't quite filtering down to the line managers yet. Trust issues, inconsistencies with applying company policies, expectations and opportunities for success and continued improvement can be a real challenge. Intelligence in the form of "book smarts" is prized above real leadership qualities which leads to ineffective and even harmful managers being promoted quickly and issues of high turnover and employee burnout abound.
