Mark Costes

Dr. Mark Costes is far from a typical dentist and dental coach. During his career, he has been able to start or acquire over a dozen successful dental practices during some of the profession’s most challenging times. But Dr. Costes’s journey was not without its setbacks.

In fact, he credits much of his success to the fact that he made more mistakes in his first year of private practice ownership than most dentists make in an entire career. What separated him from the masses, however, was the fact that he viewed each failure and roadblock as a learning experience and an opportunity to improve his business and life.

This philosophy, as well as his decision to model the world’s most successful entrepreneurs and dentists, has led him to where he is today. Dr. Costes is an international keynote speaker and the founder of the Dental Success Institute, a company committed to helping dentists to achieve their full potential, while recapturing their passion for dentistry.

He is also the co-founder and CEO of the Dental Success Network, a vibrant community of dentists from around the globe focused on maximizing access of advanced clinical and practice management education to the
profession. Dr. Costes is the International and #1 Amazon Best Selling Author of the book Pillars of Dental Success. His internet radio show, The Dentalpreneur Podcast now has listenership from over 150 countries worldwide.

Mark and his wife Leslie have three sons; Bryce, Brendan, Brady and their dog Bear. They live in Prescott, AZ.
