Falcon, greetings.

As for Spanish people they attend english classes in several places.

1.- CHN Institute
2.- British Council
3.- Berlitz LC
4.- Cedars Tutoring Center

And there are other around.

Attendance will depend on needs of the people as well as price/budget.

By the way I'm in the Latino community, if your wife needs some spanish talk just drop me an email and I will get back to you.

Best of luck.
