Took all three phases of the ACEP/SEMPA EM Academy. I found it useful and a good refresher. In no way is it a replacement for fellowship/residency but is a good stopgap especially for PAs who have been out practicing for a year or two.
I am familiar with EMA. They are smaller than other ER groups in California but has a good infrastructure. Many USC grads.The 1099 is typical and it's up to you and your financial needs if that is more beneficial or if employment with a W2 provides more bang for the buck (personally I do both). The EMA training academy is not a formal residency nor was it meant to be one. It is much more informal: no clinical practicum, grand rounds, M&M.
Assuming you are in California, If you want formal training I would recommend EM PA residency at UCSF-Fresno, Arrowhead Regional, or Kaweah Delta.
Hope that helps.
