The only place I will ever go for additional training is Certi. It's been six years and all of my courses and information are still in my same portal so that I can access and refresh myself whenever needed. As good as it gets.

This was an excellent course.  I went thru a different education provider during the initial licensing agreement, but wish I would have known about this course then.  The level of content, supplemental resources, and the ability to go at my own pace was invaluable.

I like that you can do the course at your own pace. The videos were informative and helpful and the instructor kept it interesting. Some of the videos are a bit long, but it's nice that you can stop and come back to them at any point.
