Dentist coaching and mastermind community built around leadership, systems, profitability, and practice independence.

Dental Success Institute (DSI) is a dentist coaching and mastermind community founded by Dr. Mark Costes, built around leadership, systems, profitability, and practice independence. Since 2012, DSI has helped dental practice owners at every stage tighten operations, build stronger culture, and grow with discipline. Their tiered membership programs range from self-paced resources to elite one-on-one coaching, and members report an average 49% increase in profitability and 38% revenue growth.

DSI is also home to The Dentalpreneur Podcast, one of the most popular podcasts in dentistry, where Dr. Costes interviews industry leaders on topics ranging from practice management to personal development.

Many DSI-aligned practices explore reducing PPO reliance, improving retention, and strengthening patient lifetime value, where an in-house membership plan can play a practical role in stabilizing recurring preventive care and cash flow.
