Staffing of stabilization teams

I am skeptical that there is so much money to go around at those organizations. The prices are high, but the volume is low and overhead is nontrivial. Replacing staff entirely with doctors would probably be very expensive. You would most likely need to pay significantly more than the industry standard in order to attract them, since cryonics is not widely recognized as a medical occupation.

Fortunately the skillset needed to stabilize a patient for future treatment is usually substantially lower than the skillset needed to actually treat a condition. That is what EMTs are for. I just completed an 8-hour class yesterday that certifies me to do CPR and first aid. It made me realize how just that tiny bit of extra knowledge, properly applied at a critical point (while waiting for EMS) could save someone's life.

The mission of a cryo org is to be an ambulance to the future, not to fix what is wrong with the patient. It makes sense to have well-trained laypersons doing most of the work. The team isn't there to diagnose any illness or treat any condition. The most important part is being in the right place at the right time, and following the correct procedure.

Actually designing the procedure in the first place, training the team to follow it properly, evaluating performance, etc. are the areas where a specialist is most called for.
