Here’s what people are saying

Keith is simply an excellent instructor who possesses a strong, wide knowledge base that spreads across many areas. I would encourage anyone to drop a couple Jackson’s and take this course. You will come out with more understanding of SIP than you ever expected, and the price, again, is a STEAL!! Well done, Keith! Thanks!

Chris K –

excellent class, well explained complex matters

Lars L

The course is not boring at all, which is uncommon for sip courses very informative and down to the point.
