USAP, who bought us out in Denver, has had to retain the services of both Merritt Hawkins and Kendall & Davis to fill positions that used to be filled exclusively by word-of-mouth. Using a recruiter would have been unthinkable to us 5-10 years ago.
To their credit, the salespitch seems mostly to be accurate, with the exception that the recruiters' ads don't mention overseeing AAs. As long as you know that you are working exclusively as a supervisor (of both CRNAs and AAs) , you probably won't be too disappointed. I note that the Gaswork ad states you will be doing 90% of your own cases, which, of course, is 100% wrong.
My former colleagues are all less happy than they used to be, but they dry their tears with unmarked C-notes, so there's no need to feel bad for them. The new ones don't know how it used to be, so they don't even feel like they've missed out. And, again, $450k/year isn't chump change, even if your corporate overlords are getting their take.
