1) Your employer pays for you for multiple board-certifications - that is key! 2) It's no one else's business, really. But, it's also nice to know how others view it. 3) That being said, my personal thought on multiples is that they should make "sense" together. It sounds like yours do - otherwise, it leads to speculation of how is an RN keeping up hours for Peds, Neonatal, Stroke, Post-Anesthesia, Med-Surg and Oncology, etc.... But, if they are realistically congruent and keeping them up is easily done - go for it! I sign emails, other professional items with: DNP, APRN, FCCM I sign work items with my credentials: ACNP-BC I sign the WHOLE alphabet when I'm feeling snappy or bratty about something!!! ha ha (truly, I put everything I have down and fume over whatever issue the "nurses" were not "qualified" to comment or speak on): DNP, APRN, ACNP-BC, ACNS-BC, CNRN, CCRN-CSC, FCCM
