Pros
Well-run company exhibiting civic and community responsibility as well as responsible business practices. Despite focus on a single field (healthcare), successful efforts at diversification of business model including "exporting" healthcare models to other countries and developing health-related technology. Fair salaries and excellent benefits package including low-cost family health benefits, employee-assistance programs, health and wellness initiatives, and 403b along with cash-balance plans. If one is a physician, "back-office" functions are effectively and efficiently run, leading to higher reimbursements. These functions are rated among the highest in the country among academic medical centers.
Cons
Quite Oakland-centric and Presbyterian/Shadyside-centric; if you are an employee working in the surrounding community, the opportunities for recognition and career advancement are somewhat more limited.
