Experienced and Engaging Trainers...keeping the subject matter relevent and interesting


At Lean Six Sigma Training Ltd we believe that trainers need to be both experienced and engaging so that students stay alert and interested in the material that is being taught. It is not enough that we have the best training material available.


Accredited by the Council for Six Sigma Certification ( CSSC)the International Association of Six Sigma Certification (IASSC) and the International Lean Six Sigma Institute (ILSSI)our trainers are experienced in applying Lean Six Sigma principles across several different industries. We believe that trainers also need the personality and projection to be engaging to our students with frequent real-world examples and anecdotes together with encouraging class participation and discussion.  


Our trainers take time to understand the industry backgrounds of the specific students we have in our classes (which varies week by week) and to adapt the examples and discussions to apply to those specific industries.
