I'm curious how you know of her but don't know what she does!
She is indeed a publicist for many actors.
She's also one of Laura Benanti's best friends; I believe that's how she got started in the business? I remember her actively campaigning on social media to get Benanti on the TV show Nashville because they both loved it so much and...it worked? I was just learning who she was, then, though, so maybe she was already a publicist then.
