Quite a few hospitals have women in executive roles, some who are trained nurses, and basically "call the shots" in that role.

At San Francisco General Hospital, At least 50% of the Administrator(s)-On-Duty are women. It's a mixture of MDs, and nurses. In fact, I've only personally met one AOD who is male (nurse). The AOD calls the shots on a daily basis.

BTW one recent CEO, Susan Currin is a nurse & the current CEO Susan Ehrlich, MD are both women.

IMO It's not a validation issue. Companies (Tech or otherwise) have the culture they reinforce, dysfunctional or not.
