The instructor for 4hour COVID-19 training was one the best instructors that I have had in years. Our instructor was down earth, never boring and kept the training moving along. I was surprised with all the handouts, that was a plus.

I really enjoyed Mr. Mike Gonzalez's Covid-19 Disinfection Seminar. I found the class to be very informative and well structured from beginning to end. The images, charts and graphs were and will be helpful in understanding the importance of being extremely thorough when applying chemicals. Thought Mr. Gonzalez did a fine job of keeping our attention and keeping us engaged by his enthusiasm and love of this business. Overall, I would highly recommend this Seminar to all in this industry.

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
