She needs to retire - I don't say that lightly - she is slow, still working as if it's 1992 - took so long to provide a prior auth for a upped dose of a prescription I've been on for decades - that it's been cancelled twice. Calling my cell phone on a random Friday night after 8:30pm to tell me about result she already provided. Did not suggest an endocrinologist (because her husband is one - retired btw)  when I am being treated for Hashimoto's - yet had me do an at home sleep study but some shady company - doesn't know how to pull results from portals.
