“Loved the tree climbing and aerial rescue course. I’d have been happy to carry on for another week. It was probably the best course I’ve been on. Matt and Adam provided a calm, relaxed environment, knew when to add more without overwhelming with information. The course is well structured, covers everything needed for the assessment and more. The kit provided is very good, with the opportunity to try different bits of kit for those who want to.” AO, Plymouth – Level 2 Tree climbing and aerial rescue course, July 2022
