Individuals and organizations worldwide, from diverse professional backgrounds and industries have participated in the Temperament Certification. Each participant has a unique story for how they utilize temperament in their spheres of influence. Below are some stories from Temperament Certified Professionals.

“The Temperament Certification training was an excellent investment. The materials were very focused on learning and understanding the history, the theories, the types and the usage. The Live Training was extremely helpful in understanding how others may view the types and their usage of the materials in their industries. I highly recommend this training to any individual or organization that wants to gain insight in progressing to the next level in human potential. This was one of the most meaningful trainings I have ever taken!” - Jeanne P., President, Consulting Firm, (Wisconsin)


“Our Temperament Certification has opened a new level of business opportunities with companies we work with in our Sales and Marketing training programs… It is the perfect complement to our programs, enabling us to give our clients a deeper perspective on how to engage buying influences in complex selling situations and how to frame their presentations and negotiations in a way that will resonate with their target customers. We consider the work being done by Keirsey as a best practice in this area… Our ability to tie temperament theory and application into our program was a deciding factor in our gaining a 300+ Sales Professional development program with a new client… It has also provided an instant understanding of why my partner and I have been able to work so well together, each applying our natural strengths… It is truly remarkable how true to form our profiles have been. What I especially like about the Temperament Certification program is that it is structured in a natural, no-hype, no-fluff manner with practical examples provided to clarify the different temperament types. I am able to reference these examples and use them frequently in my interactions with friends and family. It has also helped my wife and me better appreciate the evolving talents of our children and areas where we can develop a stronger bond with them. What a great gift at this stage in our lives.” - David G., Director, Sales and Marketing, (Maryland)



“Prior to discovering my temperament type, Keirsey temperament theory was completely new to me, so the realisation of my in-born drives and how I relate to the world and other people, came as a big surprise to me. Despite having participated in many personal development and training courses, the Keirsey training pulled all that previous knowledge together… I have become so aware of how I communicate with friends and family and can now, as a result of the training, quite easily steer my conversations with them, from their perspective – this makes for much richer interaction, because people like to be understood. It’s a win-win situation... Temperament Certification is in my opinion, vital knowledge for any individual or organisation and has certainly had a profoundly positive impact upon my life and I am most grateful for it.” - Janice B., Consultant / Therapist, (United Kingdom)


“Even though I am qualified on the MBTI and have been studying Type and Temperament for about 20 years, I was surprised at how much I learned that was new information. I really enjoyed the focus on observing behavior - what people say and what they do. It is so much easier to listen to what people say and watch what they do to better understand them than to try to figure out their cognitive processes. I have already recommended this training to several other coaching professionals… I think this training is excellent. Taking the live training and then doing a deep dive into the material with the online training (though a challenge for my idealist temperament) really helped me learn and appreciate the depth of the material. I am telling people that this is a wonderful and accurate resource that will help people better understand themselves and appreciate the diversity of people around them.” - Linda D., Consultant, Consulting Firm (California)


“The Temperament Certification has greatly impacted the way I approach my job. It has given me a unique perspective into what motivates and drives both my peers and superiors, which has enabled me to understand them better, and enhance those relationships. This has impacted morale and productivity in noticeable ways. This is the type of training one wishes they would have had access to at the beginning of their career. I can’t even begin to estimate the positive impact this would have made in my career early on, not to mention the frustrations and headaches that could have been eliminated along the way. I would recommend this training to any company that I work for now or in the future, at every level of the organization. As a corporate trainer, I’m in the process of bringing this training to the company, and I must say, it has proven to be among the most popular and sought out offerings we have… I would absolutely recommend this training to others. The course was well organized and paced, and the support materials were extremely valuable resources. The temperament training itself is essential learning for everyone, but in particular for professionals in a formal leadership and/or human resources/organizational development role. I sincerely believe having an understanding of temperament for these individuals can make the difference between success and marginal performance. If I was a CEO of a company, this would be required training for the entire leadership team.” - Tim B., Corporate Trainer, Telecommunications Company, (Colorado)



“After three months of working closely with the CEO, whom I did not know before, it was clear that he and I had two very different approaches to leading the company… Since undergoing the Temperament Certification training, our working relationship has improved immensely. I became aware of the Temperament Certification program through a Google search of the Internet. Even though I had read "Please Understand Me" over 10 years ago, I must say that I was quite naive about the Keirsey Temperament Sorter II (KTS II)… The Temperament Certification class also provided me with a clear and concise approach to executive coaching. The material was presented in a very comfortable setting and at a pace which allowed it to be thoroughly internalized. While my initial reason for taking the Temperament Certification training was in furtherance of creating a new business in executive coaching, it has paid great rewards in my personal life and in my relationships with others dear to me.” - David M., Chief Operating Officer, Hi-Tech Company, (Washington D.C.)


“I want to thank you and commend your organization on what I consider to be one of the best, if indeed not the best learning tools I have ever seen and used. This is truly a learning experience which I continue to enjoy and appreciate. Please accept my congratulations and gratitude for a job well done. The knowledge and insights you have provided will unquestionably assist and serve to help me in my endeavors to promote the value and need for understanding temperament in many various applications and settings. Dr. Keirsey is absolutely one of the great thinkers and contributors to the success of the on-going exploration and understanding of human behavior and temperament. My hope is that he realizes the value and impact of his contributions, which are a direct result of energy, purpose, time, commitment and research. He can be pleased and proud of the difference he has made. May I extend my sincere heartfelt thanks to him and his supporting cast. Well done.” - Ray A., Engineer, U.S. Department of Defense, (Virginia)
