This is the most legit aerial school that I have found.
I just finished my second remote training with them. They are professional and throughout in each aspect. I am satisfied with my experience in relation to content, covered areas, as well as customer service.
The course doesn’t leave areas uncovered: Rigging, Anatomy, Safety, Class Management, Teaching Methodology. The tutorial videos and the manual are easy to follow, covering skills, technique, injury prevention, common errors, and spotting. The instructors are responsive and prompt to help.
