I used Peter and SixSigma.us for all of my six sigma and lean training and certification coursework. I am now a working six sigma master black belt / certified lean agent. Peter’s coursework focuses not only on the statistics, but more importantly, practical application of statistics and project management techniques. I came out of his course not only knowing statistics and statistical theory, but how to use them to positively impact my business and related projects. I plan on using Peter for all training needs and consistently refer others in the industry to take advantage of his best-in-class training.
