I just attended one of their seminars on wound care. Worth every penny!
the speaker was very informative. lots of information of dressing choices. wound tx and she also wrote a pictorial book on wounds, their tx and healing . the book was an additional 20 dollars, but very useful in identifying wounds, staging etc.
the text she provides with the seminar is a useful resource.. email me if you have any other questions. the above mentioned resource from previous responder is also great.
