The information provided and “hands on” training was valuable for learning the basics. I feel confident to move forward in my work and incorporate After Effects into my editing.

Karen is a terrific instructor. Her in-depth knowledge and approachable teaching style really highlighted the power of Tableau and made learning fun. The day flew by and I feel equipped to go it alone.

CTS is a great training organization. Not only their trainers are all professional in their subjects, the whole team provide super support for all your need during the training and after. I would strongly suggest CTS for any training need.
