Disclaimer: As our organization has grown it has become difficult to monitor our approved providers and/or mentors. Furthermore, not all providers and/or mentors are necessarily completely honest during their accreditation application process. Although we attempt to keep our listings as accurate as possible, it is not possible to monitor all the various service providers located in our listings at all times. As such, we heavily rely on feedback from the public in identifying possible issues with Six Sigma service providers. If you feel that any of our accredited providers are not meeting our Accreditation Standards or any information contained in any of our listings is inaccurate, we kindly ask that you please let us know by contacting
