Hard to tell.  

She's been discussed on this board before without a positive conclusion, but nothing negative either (at least that I recall).

Phone number has been around for a while, but hasn't generated any reviews,  (red flag)

SOME of her pictures from this (and other) ads appear to be borrowed. (see below), but I can't say they are all fake.

May be real provider, but B&S? Seems risky to me. Stay safe and write your reviews.

Cheers,
