Pros
MHC is actually a nice place to work overall; the staff I work with (all health care providers (doctors, nurses) are professionals with plenty of experience in both health care and insurance. The company has good values, and in fact lives by them; they want people to be healthy, and providers to be paid. Senior management appears to have the right mindset (we manage care for people, not shareholders).
Cons
They have grown immensely in the past several years, and their IT systems have clearly not been a focus. Their systems for doing UM can generously be described as "clunky and outdated" (and accurately described as "an actual obstacle to getting any work done"). They have plans to transition to better systems(s), but in my judgment they took far too long to 'get' that newer systems were needed. The company has an aggressive, growth oriented strategy that has left some aspects of the business behind in the race to get ahead.
