Becoming an ADI (Approved Driving Instructor) was one of the hardest and most stressful qualifications I have ever had to go through.
It can be a complex process and given the safety Implications it is totally understandable.
ADI Training
Along my Journey, I was lucky enough to work with some good Trainers, eventually meeting Frank Eustace.
Frank is without doubt an expert of un paralleled quality.
I have been lucky enough to have been working with Frank for some time now and would always recommend him for anyone wishing to become an Instructor.
Frank can be contacted via his website and I would thoroughly recommend him.
