Bujold,
A quick search here and at Max Fisch reveals no reviews of this lady or any information about her as a Domme using a google search on the web.
What I did find, however, was a link to a FBSM provider in Oakland who does Tantric work:
Dakini Ava Maybe she does Pro Domme stuff but I can't find it, so I doubt you will get a response from anyone who has actually seen her (although I have been wrong many times before). Based on her background, I would speculate that if she does do Pro Domme then it is more Bondassage style sensual stuff rather than full on BDSM play.
Maybe if you provide a little more information, like where you ran across her and if she does BDSM using a different name that doesn't include Dakini (which is a Tantric term), someone might be able to answer.
