Uh, first of all. Please be a little more specific about your location. Second of all (this should be first), check on google, cause thats usually what we do in order to name schools in that area unless a member trains in that location and knows the studios very well.
I was going to give you a couple listings, but I thought you meant in London Ontario, there is more than one London, in fact there are probably hundreds of them.
Overall, you should be more specific if you want to get an answer quicker.
