The training addresses key elements and good practices for both beginners and expert users. The explanations are of high quality, concise, and supported by an exhaustive baggage of experience. The course explains some best practices for documenting model creation. The process of using the output of excel calculation directly in the Next-In format simplifies model generation and checking of data. The organization and presentation are more practical than previous training (with another company). The whole course reflects a lot of preparation. I’m confident my staff can take this course and become proficient at using SES.

I have been granted access to Never Gray's SES Emergency Analyses course to evaluate it as a potential alternative to future in-house training, in exchange for providing constructive feedback about the technical aspects of the course. As a fellow SES expert, I can confidently say that this course is thoughtfully laid out with a methodical progression from one topic to another. It truly makes for an excellent learning experience, enhanced by the great visual presentation of all the material. In my opinion, the Never Gray Way really shines in the way the overall process for conducting SES Analyses is presented, most importantly being, all the required documenting and checking throughout. It demonstrates how to navigate and manage the often overwhelming amount of information, which helps ensure a quality product is produced. Any Joe can run an SES model, but for it and the associated results to be trusted, this is the way to follow. Bravo Justin!

You make SES fun! Learning SES with Never Gray Way is amazing. I enjoy learning with Justin very much. He’s SES Guru and contributes so much to the SES community in many different ways. His approach to SES is very systematic; thereby making SES simple & straight forward to anyone. I never feel intimidated to ask for his help. Never Gray Way is the best way to learn SES from a real SES Guru!
