As an experienced Security Officer, I decided to expand my skills vie Door Supervisor Training Course. D.S.T.O offered a course in the area. The faciliites were very good with plenty of space when we needed it (physical intervention), and a quite environment for the training and exams. The Trainer was excellent with real world experience, good pace, and support for those with less experience. Leasons were clearly delivered with good Q&A. I would unreservedly recommend this course and D.S.T.O as the deliverer.
