is Master's Degree sufficient?

I was recently told by a nurse that starting very soon a Masters Degree in speech and language pathology will be insufficient to work with seniors and accident victims. She says that a "doctorate" will be required. I assume she knows the difference between PhD and MD, but it was a casual conversation with a virtual stranger.

Is there any buzz to corroborate what she told me?

there is no truth to her statement. as of now the top degree necessary to be licensed as a SLP in any state is a master's. with a master's (and in many cases just the bachelors for an SLPA) you can work with any number of groups, including seniors. they recently made the switch that audiologists must have a doctorate, so maybe she is assuming one day the SLP will need a doctorate too? but as of now, nothing more than the master's and clinical experience
