HIGHLY recommended. I started there two weeks ago after a week and a half at the GHETTO of ALL trucking "schools", Sky-Bay, in Fontana, CA.
ASD is right around the corner. Much better instructors (that speak english), personal attention when needed, much better equipment (although not new, they keep their trucks in very good working condition), and even though their program is 40 hours, they are giving me the 140 hours I need for TMC for not very much more.
CRST sends their drivers there I noticed. They take them to school every morning in a CRST van, then pick them up in the afternoon and take them back to the hotel.
Highly recommend this school in SoCal. You wont be sorry.
