It's not really 2 providers and 1 anesthetic it's more like 1.25 providers to one anesthetic as MDAs can supervise up to 4 anesthetists at a time. The anesthetists earn less than the MDA so it will be cost effective. CRNA in most cases don't function alone so the same applies to them for the most part as well. I have seen AA jobs posted for 190K as a 1099 as well.
