Meet Dr. 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, and Brady and 2 dogs; Bear and Hazel. They live in Prescott, AZ.

Our Mission

The Mission of the Dental Success Institute is to help dentists to achieve their full potential in business and in life.

We believe that once a dental practice is transformed from a staff dependent to a systems dependent business, the owner can achieve improved work/life balance, decreased career related stress, and increased profitability and personal income.

Our Vision

Our vision aligns deeply with our mission in that we practice what we preach. Our systems continue to evolve over time. As you know, nothing ever stays the same for long. While dental technology, dental marketing and the cost of doing business continue to evolve, we are committed to aligning with the best and brightest, allowing us to deliver up to date practice management techniques followed up with a “family like” accountability coach and group.

Your Growth

The true measure of your dental practice success is in the numbers. The true measure of your personal success is in the relationships you foster. Weather you are a listener of The Dentalpreneuer Podcast, or a DSI mastermind member we aim to deliver the most value possible to help you grow no matter what stage of life/dentistry you are in. Thank you for being here.

  • “Being a coach at DSI is one of the most rewarding things I have ever participated in. I truly enjoy watching others lives and businesses catapult. The network of quality dental professional here is unmatched.”

  • I've done over 700 hours of CE in the past 6 years, and I can say without any hesitation that the ROI from DSI has blown ever other course out of the water. After 9 months of membership, I have a 50% OH (down from 64%), revenue up 33%, and I'm now working 3 days a week (down from 4). I thought I'd have to wait until I was 50 years old to get to a 3 day work week, but with Mark's guidance, as well as the other coaches, I'm here at 33. It's always going to be hard work, but it's easier with Mark in your corner. Feel free to get my info from DSI and I'll be more than happy to speak with you.

  • This is going to sound weird, but this group has become like family. As professionals we are in the trenches most our day, and to have a group of people to surround yourself with, that are intelligent and friendly, makes things much easier for me. This group helps in every way possible, from the business side, to the clinical, to helping me simply keep my head on straight. Can't say enough good things about this group!
