I use Google to do searches, just put in the number and it will give you lots of info.  If she's been reviewed, the search results will show it.  It will also give you info on the ads she's placed on various sites.

Then click on the 'search reviews' tab, enter the provider's phone number in the appropriate box and click search.  Or you can always use the search box on your browser, enter the number and click.
