“Mark has excellent and deep founded knowledge of lean system design, lean management principles and is an experienced problem solver. He has great ability to apply and coach these skills to all levels of an organization. In the four years we have worked together at BMW, he has been an excellent mentor and leader for me.” – Stephan Moll, Senior Lean Expert, EADS

“I have had a great experience working with Mark. He is one of those persons you probably meet just once in lifetime. I  will always remember his professionalism combined with the ability to teach and motivate people.” – Franz Ganglbauer, Senior VP Production, Deutz AG

“I met Mark the first time in South America during my 3 ½ year BMW assignment, when he supported Chrysler and BMW to set up an engine plant  in Brazil. This was the first time I'd seen such a LEAN system alive. I was fascinated.  It wasn't about the LEAN Tools - it's about the LEAN System- it's about leading to a true continuous improvement culture which is not created overnight. Mark was very strongly involved in developing the right mindset and culture.  Besides his great ability to motivate and to work with people, Mark has a great competence in LEAN and  in the LEAN transformation process itself. Mark showed us over many years in a very consistent  and professional manner the difference between ‘What is LEAN?’ and ‘How can I create a successful transformation process?’ Since I've known Mark he has coached many people worldwide to become LEAN coaches themselves. It is a pleasure for me to confirm that Mark is my LEAN Mentor.  I enjoy working with him professionally and personally.” - Arnd Kaiser, Lean Management and Industrial Engineering Manager, Rolls Royce Motor Cars LTD, UK

“I have had the great opportunity to work with Mark and being coached by him in lean principles and systems; he was the principal consultant brought into the joint venture program with Toyota Production System expertise. Mark was instrumental for the success of the plant, its operating excellence and the lean culture implementation throughout the entire organization.” – Tan Liam, International Product and Market Analyst, Chrysler LLC

“Mark knows more than lean tools, he has the deeper understanding of the TPS system that comes from living in that system for over a decade.”Kent Robinson, Global Rolling ABS Consultant, Alcoa
