The idea that in this day and age dentists can keep the business side of the practice in-house is considered by some as no longer possible. One of those persons is Andrea Greer. Greer has been working in the field of dentistry for over 25 years and since 2013 has worked as a consultant and speaker, helping a number of practices and dentists improve their business and reach new levels of success. In an interview with Dental Tribune Online, Greer reflects on how dentistry has changed, the most common business mistakes dentists make and what can be done to improve business education for dentists.
