sara, I am glad that I read the answers prior to mine on your question. Shirley’s book was a huge help for me, as well as spending time learning the complexities of the fascial system. Thomas Meyers can provide you with some very easy to digest, intelligent insight into the matrix of connective tissue that makes us who we are. Mostly, from personal experience, I have found that each client will require their own unique blending of several modalities. If at first you don’t succeed, try again… Be assertive, but not bravado… Be truthful, and you will never go wrong. If you don’t have an answer for your client, they will respect and appreciate an “I don’t know, but I’ll do some research and get back to you” better than some ham-handed explanation that you make up as you go. I trust you will be helping more than tight traps very soon!
