What Our Students Say

"I think that this is probably the best class I've taken while gaining training and certificates to be a Covid-19 Compliance Officer (C19CO) in the film industry because it goes well beyond telling me what to do and actually goes into the detail of WHY the processes are necessary. It also explores which cleaning systems work for different phases of the process and WHY. I think that the videos were very detailed and helpful. I've recommended this class to my work group."
