" To say that this program is invaluable would be an understatement. As an aborist with seven years experience, I was worried about the prerequisite courses (the level ones) may be a bit juvenile for my needs. These worries proved to be unfounded. As the weeks since the programs have passed, I am finding more and more uses for the knowledge gained. This is a great program for anyone that wants to raise their skill, safety, and productivity. And yes, you WILL benefit from these courses. "
