“The training and ongoing mentoring our organization received from Ray Hemmele enabled our company to
reach a new level of efficiency resulting in eclipsing our savings goals by millions of dollars.”

— MBB, Automotive Industry


“The impact of Ray’s training allowed me personally to have the lowest project cycle times, largest total savings,
and subsequently reaching the position of Director of Performance Excellence in less than a four year period.”

— MBB and Director of Performance Excellence, Automotive Industry


“The MBB training I received from Ray was excellent. It gave me the confidence to step up and become the in-house guru for all things six sigma and lean related. It was the perfect complement to my previous BB training. Ray’s teaching style and materials were exceptional. They allowed me to build on my previous knowledge and to learn the tools and methodologies at a much deeper level. The mentoring Ray has given me since the end of class has been vital in my education. Ray has always made time for me in his busy schedule and I’ve never asked him a question for which he didn’t have a great answer. That in itself was worth the cost of training.”

“This project was a critical part of reaching our value stream savings goal for the year.  It had several complexities including internal and external involvement, significant capital investments, and challenging change management issues.  Avior Group was able to provide an experienced MBB who quickly organized the effort and
was able to elevate accountability of all team members in order to expedite delivery of the project”

“I recently attended the Avior Group Master Black Belt Training Program and am working through the Master Black Belt certification requirements. I found the 4 week training to be a tremendous experience. I really enjoyed being in the class with other Black Belts from different industries and hearing how they have implemented and use Lean Six Sigma within their organizations. Our Avior Group instructor, Ray Hemmele, was fantastic. He made the class very fun and extremely interesting as he related the concepts back to real life examples of how he has seen the tools applied on projects that he has worked on. His training modules and exercises were excellent and really helped reinforce what we were learning. The training modules have been a great resource to refer back to as I have tried to applied the concepts in the projects that I am working on. I really enjoyed the review and reinforcement of the black belt materials and found the new concepts around TRIZ, Design for Six Sigma, Time Series Analysis, as well as others very interesting all of which have open my eyes to new ways of doing things that in just a short period of time have already helped me become a better Lean Six Sigma resource within my organization. I feel that the training and Master Black Belt experience offered by Avior Group has made me a better leader and will be of great value in both my professional and personal life and I would definitely recommend it to anyone wanting to pursue their Master
Black Belt certification.”
