Thank you for the updated information, LaLaLand.
I was able to verify from multiple sources (including models.com) the move to Why Not and Success. But not to Wilhelmina and Sight. Also, it appears that he is still with Click (LA and Paris). Please give me the source of your information, so I can verify it. I do not want to update his profile (page 1 of thread) without multiple source verification.
According to COACD he moved to Wilhelmina. There's a picture which they sent out on twitter. (http://twitpic.com/339625). He's also on the Sight website http://models.sight-management.com/models/2399-garrett-neff
