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 ILSSI, CSSC and IASSC ) … or that our trainers are experienced in applying LSS 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. Out 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.

All of our experienced Lean Six Sigma Black Belts are also available for onsite consulting, coaching and for review and assessment of DMAIC projects
