Let us tell you a bit about us

We are a team of dental educators with a passion for dentistry, excellence, and education. Over the years, we have been involved in dental education in all capacities. Dentists’ needs and desires for learning both didactically and to actually implement new skills into practice are the foundations for thoughtful education. We have been privy to dentists’ frustrations with CE courses which attempt to facilitate change, but fail to deliver the necessary tools to implement new skills into practice.

We are committed to providing the support, guidance, and mentorship to minimize challenges and to facilitate learning to provide the best possible patient care. The mandate of this educational platform is pragmatic dental knowledge to implement into every day practice. We strive to help dentists fulfill their passions in dentistry and not just do it, but do it RIGHT.  Our goal is to positively impact the lives of patients and the great profession of dentistry. GDM is here to mentor you on your journey of professional growth.
