Marco, I would suggest FastLane out of RTP, NC. I just took their CCIE Wireless Lab Bootcamp which was actually taught in Toronto. Jermore Henry taught my class and he did develop some of the Cisco Courses for the CCNP Wireless track. He was great! Here is a link if you want to research this further:
There are probably only two companies taking the wireless track seriously whach re fastlane and IP Expert. Its a personal choice at the end of the day.
Have you considered training courses with a Cisco Learning Partner? The training courses by Cisco Learning Partners are highly recommended as the objectives are mapped to those of the certification exams. To locate a Cisco Learning Partner, you can use the Global Learning Locator.
Good luck and welcome to the Cisco Learning Network!

Thank you for your input on CCNP wireless providers. I will look at the options and decide my course of action. I am looking forward in becoming a CCNP Wireless.
I will also vouch for Jerome as a Wireless instructor. He is excellent. If you want a class from him, then FastLane is the place to go.
