"I completed Six Sigma Black Belt training with Steve Zagarola and Larry Mucha in April 2005. They took a pragmatic approach to training in Six Sigma tools without sacrificing a solid grounding in the basic concepts and logic associated with the tools."

Bill Redman -- CQE, SQM, CQA, SSRB


"To work with THE ZDM GROUP is not an expense but an investment. It is a business strategy based on lowering quality problems, reducing costs and saving resources with the objective of increasing productivity."

Mario Benjamin Ramirez -- Processes coordinator Alpla Mexico PET Injection

" Our people responded very enthusiastically to Steve's training in statistically sound approaches to continuous improvement such as SPC and DOE. As a result, we became the benchmark in the Middle East for World Class PET preform and plastic container manufacturing operations."

Mohamed Al Majdhoub - General Manager -- Zamil Plastics
