Yes, I attended the course in 2007. Shannon Smith was the instructor. She truly is great. I took the exam, I passed, and received the credential "CMAS" - they recently had to change it to "CPMA" - no one advised me of this (which was shocking) I happened to read it on an AAPC forum. I called to question this and they said they notified everyone via mail in May 2008, I did not receive such notice. I was told I'd have my new certificate within a week - that was a month ago and I have not received anything. I have also inquired on how we submit our "CEU's" and have had difficulty with getting a straight forward answer.
The course, the curriculum, the materials, the instructor, are GREAT! I think the other staff could work on communication skills a little better. Just my experience.
