You'll Love Learning With Us

Absolutely impressed by the training course! Never seen anything like it. Bravo for creating a way of learning that's both comprehensive and enjoyable at the same time!

I must say, I truly have not seen any other education provider with this type of service. I'm very impressed by how you've designed the training outline and content that had subcategories for expounding on methods with just the right pace for learning professionals (not too slow that it gets uninteresting, not too fast that it gets overwhelming). I love the situational examples and interactive opportunities that really kept me engaged! Even the quirks of Bahama Bistro and staff was a nice touch (pleasant humor kept things light yet progressive).

Really looking forward to Black Belt and other courses with you guys! I love!

Testimonial: Emma Austria -

I was certified as a Green Belt through another organization about 2 years ago. The training was 100% onsite in-person training.’s online training course was far superior and covered more areas than the onsite. I am looking forward to moving on towards my Black Belt now and having our teams go through the Yellow Belt and Green Belt Training.

Dale Dean -’s FastPitch simulation helped us kick off our effort with a bang. Combining the online Green Belt Training with remote coaching allowed us to target a cleanliness project in one of our buildings. The project allowed employees to better understand how their performance was being measured and, in turn, to focus on areas that had the most impact on their performance.

By the end we managed to standardize processes, reduce supply costs, and significantly improve our member experience. provided solid support and our improvement efforts are rapidly expanding. Overall amazing experience!’s courses have put our teams on the right continuous improvement path. I had a lot of fun working on my project and their templates made the process so much easier and enjoyable. I’m really looking forward to upcoming projects.

Ken Sheriff - does a great job explaining Lean and Six Sigma in an easy to follow format – and that’s not an easy task. It’s what got me interested in their courses. The customer service they provide have exceeded my expectations. The Voice of the Customer is alive and well at

Scott Lamon -

Each Lean Six Sigma project resulted in decreasing steps in a process, improving quality to customer satisfaction, and saved resources.

Jennifer Traufler -

The web-based training from gives a lot of flexibility in terms of when you can take the courses and exams.

The previous training we went through was a week-long boot camp and there was no commitment to do any project afterwards. A week-long spent in class was too much class time and exhausting. Hence, we walked away with some knowledge but that knowledge didn’t quite stick since we didn’t apply the learning anywhere.

The second approach (with was a training where we were applying the tools to a real project which solidified learning much better.

I thoroughly enjoyed your Green Belt course and believe it to be comprehensive and very easy to use.

We have found the resources and templates particularly valuable as we build our team and establish standard work for our projects.

Register today and you'll learn how to solve problems and improve processes using Lean Six Sigma – in any industry or function.

Good training overall. Was impressed with the breadth of the course and I feel I have walked away with some good applicable tools. My biggest mistake was taking the entire Yellow Belt training course prior to purchasing the Green Belt. Yellow Belt slides were interspersed in a way that made it impossible to not redo them entirely. I recommend this course!

Quick and interactive

very detailed, but long lessons, I wish it would have shorter lessons.

Great training!

solid comprehensive training with real life examples stressed

Perfect training for when your available time is limited. You are completely flexible when to complete the modules.

Great course. Excellent examples used throughout to explain the DMAIC methodology!

I wish I had done this years ago. Great practical method of using a scientific process thinking to improve our day to day thinking. I am suggesting other co-workers complete this. The training content and examples are easy to relate to, understand and apply.

Very practical overview training for project managers working in a lean 6 sigma environment!

Good training!
