Top notch company! Very easy to do business with and they practice what they preach. I'm very pleased that I selected them as my LSS training provider.

The service has been prompt and timely. I will say it seems like our dedicated rep changes very often. It has also been a more time consuming task in the past to add folks to the platform. Since the most recent updates to the site, you can now purchase and practically enroll an employee yourself, this makes it a much smoother process.

I liked that it was self paced. I didn't feel rushed to get it all done. I also liked you could go back and review certain section if you didn't pass that part of the test.

The Lean Six Sigma course work, case study, examples and exams were really well done. I recommend this course.

Go Lean Six Sigma has very good online Green Belt training. It is easy and informative for our Green Belt candidates without taking as much time as other packages. The belts seem to like the Bahama Bistro simulation that is given throughout training. We are very happy with the service and support of Go Lean Six Sigma as well.
