Pros
Their values are evident with each action that takes place. The top priority is always the experience of patients and how to make improvements that benefit both visitors and staff. Very reasonable assessment of pay and benefits; they're non-profit but remain competetive with other employers in the area. They foster a culture of kindness, saying 'thank you', and caring for employees needs and work-life balance.
Cons
I don't consider this much of a con, but just to fill the required space - they've grown really rapidly. It can be hard to implement processes that work on a large scale that are built on a small-scale foundation. There are still improvements to be made, but they address them pretty effectively.
