Welcome to PH Diversified's Online Store. Here you will find all the books that we are currently publishing.The Programmed Instruction series is for Level I. These books have quizzes at the end of each Chapter and at the end of each book. These books are great for self study. The Classroom Training series is for Level II. These books are more useful in a classroom setting.

All of the books also come in E-BOOK format. You will be mailed a Flash Drive with the PDF document on it. If you prefer a CD, we can do that too. Just let us know. There is extensive page linking and bookmarks which make the books very easy to navigate. Check out the sample on the homepage to see how it works.
