There are some good options in So Cal. Its a fantastic experience when done right. Nirvana and Isis both offer nuru I believe. Veronica45 and Mestiza - active on other boards - also offer nuru. One of the Asian agencies occasionally has a provider in town who will specialize in nuru massage as well. Up in the LA area there are other options, which I have not tried but which look very interesting. Mynurubliss and Pamela Balian are both highly recommended. You could also go on Backpage and use nuru in a keyword search - lots of interesting results!
I was glad to read about your new found obsession for the Nuru massage. Its quite tantalizing and there's nothing like it, when done with the right person. I have plans to visit San Deigo in August. Please check out my website for more details and let's go Coo, Coo for Nuru!
