- Cornerstone Testing

I was extremely pleased with the Six Sigma training that was provided to members of my organization and me. The teacher customized the training, included a lot of hands-on activities and shared real life experiences to meet the needs of our service organization. The instructor is a talented teacher of adults and intuitively senses when students grasp the concepts being presented, and hence knows when to slow down and/or spend more time on a topic.

I now fully understand Six Sigma and feel the course was very effective. The instructor was very courteous, answered all questions, very knowledgeable, and professional.
