My previous company, Thermo Fisher Scientific, in the biotech, medical device, and pharmaceutical industries is one of the most trans friendly companies I've ever experienced. It's the main reason why I joined them after grad school. I started out of grad school as a Project Manager for them.
I work for a company now that offered me a better opportunity, but it was a very amicable parting. I find that a lot of the companies in the sector though are overall very similar.
