Does anyone know of a really good provider who specializes in nuru massage?

I have performed a nuru massage. its a work out, but fun.

Second vote for Nirvana

Beware providers who say they offer nuru, but don't have the set up for it.  Ask them if they use a mattress and authentic nuru gel or at least the equivalent.  Also they should offer to shower with you beforehand.  To work properly, both bodies need to be wet before application.  The best I've experienced in town are Nirvana and Mestiza.
