Alcor keeps a list of cases on their website. I've only read the ones linked to me as "horror stories", but it seemed blatantly obvious that it's a DIY job being done by people with minimal familiarity with the technical and managerial aspects involved. It's entirely possible that perspective is biased by the specific ones I read, but it's definitely not anything that (currently) requires a degree, and my perspective was that you could probably get trained up to Alcor's "state of the art" in a few weeks plus participating in a couple of actual preservations for practice.
