The author's years of experience in building and maintaining a studio make this book a good read for a teacher who perhaps majored in performance and needs help formulating their studio, or for a teacher who has things running and needs to step back and take an assessment of how things are going.
Content probably would have gotten 4 stars, but the book would be much better with some editorial work - the grainy cover, pixelated interior font, clunky formatting, and incorrect grammar and punctuation greatly detracted from the content of the book.
