The Man Behind $200 Million in Orthodontic Growth, and What He Teaches Practices About Real Results

Luke Infinger does not sell doctors a bigger ad budget. He hands them a system, and the numbers his partners post are hard to argue with.

There is a moment many successful orthodontists reach where growth simply stops feeling possible. The schedule is full. The team is stretched. Revenue has plateaued, and the only obvious lever left is to open another location, which means more overhead, more complexity, and more of the owner’s attention split across more addresses. It feels like the ceiling of what a practice can do.

Luke Infinger has spent his career proving that the ceiling is usually an illusion. Across the practices he has worked with, he has helped drive more than 200 million dollars in growth, and the striking part is how often that growth comes not from adding locations but from getting far more out of the ones a practice already has.

A weekend that changed a four-office practice

Consider Harvey and Thomas Orthodontics. When the two doctors came to Infinger in early 2023, they had a familiar problem. They had been buying growth by adding offices, and each new location brought more cost and more chaos. As of that March, they were on pace to invoice about 4.5 million dollars for the year across four locations. They needed more production from each office, not a fifth address.

What followed was not gradual. In a single weekend that March, they hired more than ten new employees and committed to installing Infinger’s operating framework exactly as prescribed. It demanded a real emotional and financial investment. Both doctors had to challenge long-held beliefs, rebuild internal procedures, and question nearly everything about how they ran the practice. By the end of 2023, they had invoiced over 9.5 million dollars, adding 5 million dollars in growth in roughly nine months.

The pattern repeats across very different practices

One dramatic case could be luck. A portfolio of them starts to look like a method. Dr. Fishbein came to Infinger doing about 2.6 million dollars a year. By tripling his marketing budget and rebuilding how the practice converted interest into booked patients, they lifted his return on investment tenfold and boosted online conversions by 500 percent. Seven years into the partnership, his practice generates more than 26 million dollars annually.

Dr. Ed Wentz already ran a highly successful nine-office operation when the two met. Raising his visibility and optimizing his lead generation grew new patient exams by 61 percent and added 4.5 million dollars to his top line in the first year alone. Dr. Craig Murphy bought a small practice in New Orleans, trusted the team to bring his staff up to speed, and generated 2.2 million dollars in new revenue. Dr. Kyle Sparkman, 17 years into business and feeling that growth was behind him, moved from 8 million to more than 10 million dollars in under two years and found himself booked out six weeks with three doctors.

Systems over spending

The through line in these stories is not a marketing gimmick. Several of Infinger’s partners describe something that sounds almost unglamorous: a framework, installed to the letter, that reorganizes how a practice attracts patients, converts them, and delivers care at scale. One doctor put it bluntly, saying the value was not somebody spending money on Google but somebody who took the time to learn his brand, his team, and his market, then coached the entire staff rather than handing over a plug-and-play campaign.

That distinction matters for any practice owner tempted to equate growth with ad spend. Money poured into advertising without a system behind it tends to buy expensive leads that leak out of a broken funnel. Infinger’s approach starts inside the practice, tightening the operations and the team so that every new lead has somewhere productive to go. Sometimes the advice even runs counter to intuition. He once counseled a doctor to close a location that had become a drag on the business, and that subtraction set up the practice’s biggest year yet.

The specifics vary from office to office, but the receipts do not. Anyone curious about whether these outcomes hold up can review the documented orthodontic practice growth results directly, with named doctors, real revenue figures, and the timelines behind each turnaround.

What the framework actually touches

It is fair to ask what a growth system like this changes on the ground, because the word framework can sound abstract. In the practices Infinger works with, the answer tends to reach into every corner of the operation at once. Hiring and staffing get rebuilt, sometimes dramatically, as Harvey and Thomas showed when they brought on more than ten people in a weekend. The way a front desk answers the phone, converts a call into a booked exam, and follows up with a hesitant patient all get examined and rebuilt. Marketing spend is redirected toward channels that actually produce, and the practice’s visibility is raised so that more of the right patients find it in the first place.

The common thread is that none of these pieces works in isolation. A bigger marketing budget fails if the phones are not answered well. A great clinical team stalls if new patients never make it through the door. By treating the practice as a single connected machine rather than a collection of separate departments, the approach fixes the bottleneck that is actually holding growth back, which is often not the one the owner assumed. That is why Infinger’s counsel sometimes means spending more and sometimes means cutting, as it did for the doctor he advised to close an underperforming office on the way to a record year.

The scale of the aggregate number, more than 200 million dollars in growth across his partners, is really the sum of these individual rebuilds. It spans solo practices climbing from half a million dollars in production to multi-office groups adding millions in a single year. The range is the point. The method is not tuned to one size of practice or one stage of maturity. It is tuned to the parts of a practice that most owners never step back to examine.

Why the mindset shift comes first

Read enough of these testimonials and a theme emerges that has little to do with tactics. Almost every doctor describes a moment of fear before the breakthrough. One admitted he was scared at first, stuck at 500,000 dollars in production, before climbing to 2.5 million. Another opened his practice six weeks before the pandemic, followed the system anyway, quit his corporate job inside a year, and now averages 35 new starts a month. The tactics are teachable. The willingness to challenge your own assumptions about what your practice can become is the harder prerequisite.

Infinger has packaged much of that thinking into a best-selling book series that pulls back the curtain on how eight-figure orthodontic practices actually operate, from their systems to their strategies to the mindset that holds it all together. But the books are an on-ramp, not the destination. The real product is the transformation his partners describe: practices that stopped equating growth with more locations and started building the internal machine that makes each location dramatically more productive.

For an industry where so many owners quietly accept a plateau as the natural end of their growth, that reframing is the whole game. The plateau, it turns out, is rarely the market’s fault. More often it is a system that has not yet been rebuilt, and rebuilding it is exactly what turns a stuck four-office practice into a nine-and-a-half-million-dollar year.
