I completed the level one non- confrontational interviewing course approximately five years ago in Nottingham England.

Without doubt it was the best course I have ever done pertaining to investigations and obtaining the truth. The leader was absolutely fantastic and engaging. I have used the WZ method ever since and without doubt it changed my perception of interviewing and without doubt it’s the best way of obtaining the truth and developing the admission and substantiating a case value. The assumptive questions and breaking down resistance due to the techniques encouraged are superb.

I have had some real success stories in conducting investigations ever since and I would recommend any Loss Prevention professional get on the course. It really was that good.

To decant the experience of top level interviews over several years into a two day course is an amazing experience. To have the course delivered by someone with the professionalism, experience and humour of Alan is simply perfect. Overall a great course. I hoped to learn a little, I didn’t, I learnt a lot.

I have 30+ years of interview training and experience, and conducted thousands of interviews using many styles. WZ is extremely useful and will make me a better ‘all round’ interviewer.
