Now that we're doing signs, I'm able to easily follow along with the videos to learn the signs and I love that he goes slow enough that if I'm having a hard time with the signs, there's plenty of time for me to figure them out before he moves onto the next." —Erika Hellbusch

I will need to redo some of the technical parts when the time comes to use this knowledge, so I am glad I have lifetime access." —Tom Caelli
