  • “..may I say it is rarer that I ever have gotten a personal reply from a CPE Site! Glad I have found your site.”

    - Tom

  • I wanted to compliment you on the Accounting Fraud – Recent Case Studies (AUCASEMC) course I just took. The ebook was fantastic! Concise, easy to understand, very well structured, and very interesting. Exactly the way I like it. Thank you for putting it together. I feel it took me enough time to be worth 2 CPEs, but it was fantastic nonetheless. Thank you.

    - Mark R.

  • You guys do a great job!  As a person in industry it can be really expensive to stay current and you have great options that are actually useful as well as cost effective!
