Colorado club with drivers training

apple

I have a friend in Colorado who may want to take some driver training courses.  I have found that the club sponsored courses are as good as those by professional driving schools.  Thus, paying twice as much for a course by professional is not desirable.  I think that would include FASST
Are there any clubs in the Denver area that sponsor driving schools   and   do not restrict it to the make of the car - like PCA.  ????
In our area this can be done with BMWCCA and Alfa Romeo club.  However, the Alfa club pretty much restricts the students to those who are at an advanced stage.
