Is Goldwell made by Wella?

I just a called a salon to make an appointment for a highlight.  This salon advertises they use Goldwell.  When I asked to confirm this the hair stylist said that they use Wella, that Goldwell is made by Wella.  Does anyone out there know if this is true.  Is Wella a good product for highlighting fine, thin, hair.  I've had experience with Goldwell hair color and it was gentle on my hair.  I don't know anything about Wella.    

Thanks Karen.  Now I'm really upset.  I have been searching for a new hair salon for months.  I saw someone the other day with fine hair and I asked her who does her highlights.  I called that salon and they told me Wella makes Goldwell.  Now what can I do can I trust them?  I made an appointment with them for Dec 8.
