About Dr. Cassat

A Dentist Who Understands the Business — Because He’s Lived It

D. Douglas Cassat, D.D.S.

Dr. Cassat has spent more than 40 years in dentistry, building, growing, and ultimately selling his own successful dental practice. Throughout his career, he experienced firsthand the challenges dentists face beyond the operatory — managing finances, making high-stakes decisions, leading a team, and balancing professional success with personal fulfillment. 

After decades of clinical practice and practice ownership, Dr. Cassat made the intentional decision to transition into consulting and financial management. His goal is simple: to help young dentists avoid costly mistakes, gain financial clarity, and build practices they’re proud of.

Why Dr. Cassat Works With Young Dentists

When Dr. Cassat graduated, there was little guidance on the business side of dentistry. Most lessons were learned through trial and error — often expensive error.

 Today, he sees many young dentists facing even greater pressure:

  • Significant student loan debt

  • Complex practice purchase decisions

  • Rising overhead and staffing challenges

  • Uncertainty about long-term financial security

Dr. Cassat believes young dentists shouldn’t have to navigate these challenges alone. By sharing practical insights earned over four decades, he helps clients move forward with confidence rather than guesswork.

 

Real-World Experience, Not Theory

Dr. Cassat’s advice is grounded in experience — not textbooks or sales incentives.

He has:

  • Practiced dentistry for over four decades

  • Built and managed a thriving dental practice 

  • Navigated economic cycles and industry changes

  • Successfully transitioned and sold his practice

This perspective allows him to offer guidance that is realistic, honest, and immediately useful.

 

His Approach

Dr. Cassat works closely with each client in a collaborative, mentor-style relationship. He takes the time to understand your goals, concerns, and financial picture before offering recommendations.

 Clients value his:

  • Straightforward communication

  • Calm, steady perspective

  • Ability to explain complex financial concepts simply

  • Focus on long-term sustainability, not quick wins

There are no products to sell and no one-size-fits-all solutions — just thoughtful guidance tailored to your situation. 

Outside the Operatory

Having stepped away from full-time practice, Dr. Cassat enjoys sharing the lessons learned over a lifetime in dentistry. He finds fulfillment in mentoring the next generation of dentists and helping them build careers that are both financially sound and personally rewarding.
