I read this book and gave it to a friend with a med-spa business. While much of the book applies to physician practices my friend called me to say how excited she was about all the information she is going to put to immediate use in her spa. This book is very well written and makes obvious the expertise of the author, Ms Whitman, in the field of aesthetics businesses, and also in being able to relate her experience and knowledge to other business people in the field for their advantage.
