Tips Needed on Becoming a Trauma RN

Hi to all! I have been an ER nurse for 2 years now and feel it is time to move on to the next chapter of my nursing career. I was hired as a new grad straight into ER so I have no previous nursing experience. I now want to go into trauma nursing.
I live in South Florida and wanted to know tips on what are the next steps I need to take to pursue my goal. I know there is a TNCC course but want to know if there is any other certification, course, exam I need and/or should take.
Your help and tips are greatly appreciated!
Are you CERN, PALS, ACLS, CPEN etc etc certified? That would be a good start since you never know what kind of trauma you are getting into. TNCC would also work I think.
