I recently attended The G4S Phoenix ATOM course, the student to instructor ratio was spot on. The course was set at the correct level, the instructors truly are at the top of their game and still operate as Paramedics including one who operates on the air ambulance. All the basics required were covered however the instructors with their vast experience were full of great hints and tips. The final assessment was a great experience and it really took me be surprise, that's all I wish to say to prevent ruining the course for those who's choose to attend.
