SSM acquired full ownership of Dean Health Plan (DHP) in 2013, and continues to slowly integrate DHP into the SSM 'family'. However, Dean Health Plan is not a typical SSM Health subsidiary - most SSM subsidiaries are providers. There are a lot of SSM Health policies, initiatives, etc., that are clearly based on the assumption that the subsidiary is a healthcare provider, and yet these policies are still applied to DHP just for the sake of adhering to corporate policy. Within DHP, for the 3.25 years I worked there, employee turnover was pretty high. Key leadership turnover was also very high - there were 3 different CEOs during my tenure and two chief actuaries (I reported to the chief actuary). No one seemed particularly concerned about the high employee turnover and taking steps to prevent it. My manager forced me into rating a well-performing employee who I managed, and who was a great asset to the company, as not meeting expectations on his annual performance review, citing his "attitude".
He made other vague criticism that wasn't actionable, and some of which was counterproductive (suggesting I wasn't a 'good fit' as a manager rather than mentoring me and giving specific feedback for potential areas of improvement). I know this was poor management because I was making the extra effort to learn about becoming a better manager while I worked for him. My last manager also continued to make negative statements about an employee he fired, both in meetings with just me and meetings with all of his direct reports, for nearly two years after firing this employee.
Though there's a lot of great people working at Dean, overall leadership lacked stability and many high-ranking employees weren't as competent and knowledgeable as they should have been.
IT policies seemed to simply advocate for any security increase without regard to loss in efficiency, which often hampered my team's productivity. Certain things would be described by IT as "against policy", but I was unable to locate an official source of these policies. I once raised security concerns in advance of a meeting with IT, and based on their response, they seemed to think it was my personal problem. However, I was simply trying to share some security vulnerabilities to help them do their work most effectively.
