“I had the privilege to attend a Lean Six Sigma (Yellow Belt) class directed by Mark. His teaching methods are very effective; he made everyone feel part of this team, and encouraged every student, creating a professional but friendly atmosphere in class; during class he established himself as a leader not because he was the teacher, but because of his knowledgeable and passionate approach to teaching. He maintained high quality standards throughout the event. “
