It is so much information but it came together as we got into the classroom. Knowing the science behind it makes me feel more confident it my “consultations”. The in person segment was awesome. It was nice to be able to touch and run the machines. The instructors explained that every machine is different and stressed the importance of the manual. All of the teachers offered help in any area I needed. They were all so sweet and easy to work with. I loved each and every person for their own reason! The would share their experiences and techniques, and ask if we wanted to review them. They would walk us through different scenarios and stressed safety, safety , safety!
