Anyone attended American career college?

I'm thinking about attending ACC in Los Angeles for there Health claims examiner/ Medical biller program. I like the fact that I will also be learning how to do claims which gives the opportunity to also work @ Insurance offices and the training to work @ dental offices. I have looked at other schools and they don't offer the same course, what the other schools offer is just basic Medical billing like to work @ a doctors office or clinic. The thing is I have read bad reviews about this school but in reference to the LVN program i can't find any reviews on Medical billing programs So if anyone out there has or knows anything it would really appreciate you let me know before I sign the paper work, thanks
