"Dear Mr. Speer & Greenlight Guru,

I was hired by the FDA in 1976 to help implement the new Medical Device Amendments to the FD&C Act. I left FDA in the late 1980s and worked for several large medical device manufacturers to help them with compliance issues. I have seen literally hundreds of documents prepared by QA/RA departments of large device firms and by numerous consulting firms.

I just wanted you to know that I have not seen anything that equals the quality of content in your presentations. I am Impressed. I may take advantage of more of your free downloads.

Thanks, and Keep up the Good Work!!
