Larissa Bunker

Chief Operations Officer, Pro Moto Billet & Fastway

In my position as Chief Operations Officer of a small manufacturing company, this course (Lean Six Sigma Black Belt Certification) has provided structure to my continuous improvement efforts in manufacturing, shipping and receiving, finance and research & development. This year, the company has experienced great success with quick wins, kaizen events and measurement charts/KPI’s tracking improvement on measurable CTQ’s. For many years, I have studied the lean and six sigma improvement process. As I cross the finish line on this course, I feel that I have the skills to make a measureable difference leading DMAIC projects. THANK YOU for putting together such a quality course!

Quality Improvement Project Manager, WellCare of South Carolina

My (Lean Six Sigma Black Belt) course book and the Simulation Workbook are worn out! I have been referring, re-reading, and applying the  principles and tools in my responsibilities as a Healthcare Project Manager – Quality Improvement. I appreciated the design of the program: coursework, application to a real-life project, and the tollgate checks when I was going through the program but the real value came when I got into a position that I applied the methodologies to build efficiencies into Lean Six Sigma projects. I highly recommend the Acuity Lean Six Sigma Black Belt Certification Program. It wasn’t easy but it was worth it!

The online training (Lean Six Sigma Black Belt Certification) was very inspirational and energizing. It brought lots of ideas, with both substantial and in-depth knowledge together with case studies, experience-based learning and project immersion. Well-balanced composition of content, which contributed to interesting and focused lessons and material. I have referred numerous students for training with Acuity as a result.

This [Change Management Professional Certification] is a great course!  I have paid for many university-level online courses, and rarely have I enjoyed, or felt rewarded the way I am with this course.

I highly recommend Acuity Institute if you are considering taking courses to obtain professional training and/or certifications. I have taken classes through other companies and Acuity has clearly set a standard that they did not meet. I enjoy having written material to review or refresh and Acuity makes that possible. The courses are reasonably priced. They are responsive. I have received responses the same day. And, everyone is polite, helpful and professional.

If you are looking to gain the REAL knowledge needed to move forward, go with Acuity.

I would like to thank you and your entire team for a truly wonderful experience.  Of all the training courses I have ever participated in, the Lean Six Sigma Black Belt Certification course was by far one of the most comprehensive, yet to-the-point, and best run technically that I have ever seen.  I will gladly recommend the Acuity training program to all of my colleagues as a great value in every regard.

Certified Acuity Institute Lean Six Sigma Black Belt

I really love the Lean Six Sigma Black Belt Certification course.  I have never done online training before and I did find it somewhat challenging to stick to my own schedule sometimes. However, the content was EXCELLENT!!  The Presentation very well done!! The Simulation absolutely appropriate.  I have since read several books on Lean Six Sigma and I find that your course is the MOST THOROUGH resource. I have been recommending your program and I will continue to encourage my peers to consider your program.  This Certification is enabling me to pursue a career in Health Care Consulting and to make a valuable contribution to this troubled world.  I am encouraging others to do the same.

The Simco Simulated project was essential to the overall Lean Six Sigma Black Belt Certification program. Before applying the various charts and tools, it was not apparent to me why one certain chart would be better than another. The simulated project really drove home the points covered in the materials.

Danielle Peotter

Certified Acuity Institute Change Management Professional

The Change Management Certification course with Acuity was incredibly easy to use and applicable to my job as a Success Manager. I am able to employ tactics in my onboarding and vision discussions with customers that are effective and well received. This class also helped prepare me for the CCMP certification. I would definitely recommend the course!

Matias Johannessen

Certified Acuity Institute Lean Six Sigma Black Belt

I have taken Lean Six Sigma White Belt, Yellow Belt and Black Belt Certification in addition to the Kaizen Workshop (a total of 199 PMI PDU’s) with Acuity and I intend to continue expanding my professional toolbox with them. I have a family and a full-time job which means I require a highly flexible learning-environment without any compromise in quality. The Acuity staff were professional, helpful and offered their full support throughout my learning-process.

I mainly interacted with Kimberly during my learning. I give her absolute top-remarks in the following categories: Customer Support, Professional Guidance and Professionalism. You truly have an asset in her and her support was important in my decision to take 199 PDU’s with you. I look forward to further expanding my toolbox with you (looking at Change Management Professional as my next step, after alot of good advice from Kimberly). Thank you for the good job Acuity is doing providing buiness tools.
