I’m extremely pleased with my ISO 45001 Lead Auditor course from deGrandson that I started in February 2021. I work for Amazon as a Construction Manager constructing fulfilment centers in the UK, EU and worldwide. The course material is excellent, the online learning system is very easy to use and the course is very well structured. I highly recommend this course by deGrandson. Dr John FitzGerald is an expert in this subject area and it shows. You will be pleased that you also chose to study with deGrandson.
