I am a dentist; I work with the Ministry of Health,We are trying now to work on improving the present dental school health programI attended a workshop by Bill Smith and I read your book about fostering sustainable behavior. But we still need a lot of work.We did what you suggested in your book, but we need to know more and to know how to use the new knowledge we gained to implement a new and a better program. I would like to thank you very much for your book it helped a lot, but if there is any other books I would appreciate it if you can send me the titles.
