I have the privilege of bringing Patti DiGangi to you. Patti is a hygienist of over 30 years, filled with vision and passion for our industry more than ever. She empowers hygienists all over the country with her courses and inspires me to be the best hygienist I can be for my patients. I refer to Patti as the Queen of Coding. I am always learning something new from Patti. And, I especially love her little book, DentalCodeology More than Pocket Change. She has made periodontal coding so simple to understand and easy to follow in this handy book.
