About Us

It’s not just about a great living. It’s about a great life.

If you left your dental school graduation full of ideas about helping patients and living a life of respect and success, only to find yourself trapped in a never-ending cycle of business worries, you are not alone.

It’s wrong to pay a small fortune for a dental degree and leave without the know-how you need to run a business that enables you to not only help people but also to enjoy your own life.

At NextLevel Coaching, we get it.

There is a better way. For more than 20 years, we’ve helped 6,000 practices just like yours embrace and implement a new way to practice dentistry. Through expert coaching on how to implement our proven, unique business model, we’ve seen dentist after dentist find the satisfaction they were dreaming of on graduation day.

We are committed to helping you build your practice on a foundation of integrity and empowerment so you can form a cohesive team, employ powerful automations, and educate your patients on your important role in helping them achieve Complete Health.

Find the Potential

There is hidden revenue in your practice, and you don’t have to see new patients to find it.

Dig in With a Coach

Our proven strategies will help you implement a simple, predictable business model that takes you to (you guessed it) the next level.

Total Transformation

Revolutionize your practice and your life. You deserve to spend more time with your patients, your family and your hobbies.

You deserve a practice that allows you to focus on what’s really important—dentistry that gets patients healthier and the time and means to enjoy your own life. We’ll help you transform your practice so you can live your life to the fullest.

“Our projections were declining, there were inconsistent patient results, and our staff just wasn’t a team. Now our patients are healthier, our team is much more cohesive, and there’s enough money left over now to pay down debt, upgrade the practice, and to move toward financial independence.”

Meet Our Team

Gary Kadi

Chief Executive Officer & Founder  |  New York, NY

Gary has worked to empower dentists for more than 20 years. After watching a movie that poked fun at dentists, Gary discovered his life’s mission: altering America’s health by transforming the way the public relates to dentistry.

Gary realized that dentists rely on a broken business model that focuses on attracting new patients instead of engaging and educating current ones. After years of studying the recurring challenges that dentists face (team dynamics, finances, high patient turnover, etc), he created NextLevel Practice and the Complete Health Dentistry model.

He is inspired every day by the courage and personal successes of dentists and their teams, and his goal is to help create practices where teams embrace and implement change, patients respect their treatment regiments, and doctors enjoy practicing.
