I did ISO 27001 lead implementer course with sentinel. Very practical and Interactive course that provides a roadmap for setting up an ISMS from Scratch to right to the end. I am using what I learned to set up and ISMS where I work.
The trainers were on point in delivering the content in terms of knowledge-wise and professionalism. The fact that they are practicing what they are teaching makes it even better.
In addition, the company provided excellent customer service and support throughout the training.
I would definitely recommend taking training with sentinel
