Leon Bowler

Managing Director

Leon has been an inspirational, lean six sigma practitioner, facilitator and coach for over 15 years. He convinced himself of the power of Lean whilst working as a Senior Production Manager, supplying Kimberly-Clark and their range of Andrex products. Leon found himself in a critical situation where scrap was over 12% and the customer was almost lost. The team took the leap of faith and fully committed to Lean, with Leon leading the charge. This resulted in scrap being reduced to under 2% and his company winning supplier of the year.  Once realising what Lean and Six Sigma could do for people, Leon never looked back.

Since becoming a Teacher Leon has educated and qualified over 400 people in Lean & Six Sigma qualifications, within such organisations as Bombardier, AVK, Trelleborg and BCA. In the last 5 years Leon has been directing the Teaching Team within Qualitrain Ltd and is passionate about developing curriculum that simplify the Lean Six Sigma methods so they can be understood and competently applied by a much wider audience.
