It should be accurate if the reviews are recent. If she's not reviewed, perhaps you should see someone else.

GOOGLE her email address and phone number...
You might find other ads on other websites, which list her rates.

& Is she reviewed, ask other reviewers, who have reviewed her.

In an email I express my desire to schedule some time with her...I include verification info and a little about myself...then I say something like " I never bring up the subject of rates in an appt request , but if your site mentions rates I fear I missed it.  I know what it says on  your TER profile but I do not want to assume that is accurate or current.  So you might have to give me a heads up...thxs".  

If not, you'll have to ask.
