Mortenson Dental Partners and Your Practice: What Owners Should Know in 2026

You get the letter. You type the name into Google that evening, expecting to find the usual private equity sponsor behind it.

You don’t find one.

Mortenson Dental Partners says it has none. Its own materials put the figure in large type on the front page: $0 private equity.

The organization describes itself as owned entirely by the dentists it supports and by its team members, through an employee stock ownership plan.

That is unusual enough at this scale that it deserves a proper look rather than a shrug. Here is what it actually means, and what it doesn’t.

Key takeaways

• Mortenson is dentist- and employee-owned, not private-equity-backed. Its own disclosures state 100% dentist and employee ownership through an ESOP and zero private equity.
• It buys existing practices, and steadily. Five acquisitions in 2025, with its supported-practice count moving from 144 in March 2025 to 156 today.
• The affiliation process is published and repeatable — six defined stages, from informal conversation through integration. A practised machine, not an improvisation.
• Repeatability cuts both ways. A process refined across dozens of deals is efficient, and standard terms are terms someone else drafted.
• Your practice name may or may not survive. Mortenson runs eleven regional brands, and acquired practices are sometimes folded into one of them.

Does Mortenson Dental Partners buy dental practices? Yes, and regularly. Mortenson affiliated with five practices or groups in 2025 and supports 156 practices across ten states.

Unusually at that size, it reports no private equity sponsor. Ownership sits with supported dentists and team members through an employee stock ownership plan.

Who Mortenson Dental Partners actually is

The clinical lineage starts in 1979, when Mortenson Family Dental was founded. That brand alone has grown to more than 30 locations across Indiana, Kentucky and Ohio.

The support organization around it now covers a good deal more. Mortenson Dental Partners reports 156 supported practices and more than 2,500 team members.

Its own materials name ten states: Kentucky, Indiana, Ohio, Utah, Iowa, Nebraska, Texas, Missouri, Georgia and South Carolina.

Two terms are worth pinning down before we go further. The whole article rests on them.

A DSO is a dental support organization. It is the management company that owns the non-clinical side of a practice and handles everything outside the operatory, while a licensed dentist keeps ownership of the clinical entity.

That split exists because of the corporate practice of dentistry doctrine — the body of state law restricting who may own or control a dental practice.

An ESOP is an employee stock ownership plan. The IRS defines it as a qualified defined contribution retirement plan designed to invest primarily in the employer’s own stock.

In plain terms: instead of an outside fund holding the shares, the shares sit in retirement accounts belonging to the people who work there.

Mortenson says all team members are enrolled automatically, at no cost to them. Eligible doctors can also buy additional stock directly.

That combination — real scale, no outside sponsor — is rare. Most organizations supporting 150-plus practices got there on institutional capital.

Does Mortenson buy existing practices, or build new ones?

It buys. This is the question that kills other profiles in this series, and Mortenson passes it cleanly.

Look at the sequence rather than any single deal.

February 2025. West 10th Dental Group affiliates, bringing four Indianapolis-area locations, one of them a multispecialty hub offering orthodontics, periodontics, oral surgery, pedodontics and endodontics alongside general dentistry. That took the supported count to 144.

June 2025. Millard Oaks Dental joins the Summit Dental Health region.

September 2025. Milford Dental Clinic and Fallbrook Family Dentistry, both founded by Drs. Janna and Jeffrey Spahr, affiliate and take Summit Dental Health to 13 practices in Nebraska and Iowa.

Supported count: 148.

Across 2025 as a whole, Becker’s Dental Review reported five completed acquisitions alongside organic growth running at roughly twice the profession’s average. The orthodontic brand American Family Orthodontics added fourteen locations in the same year.

Today the number is 156. That is a dozen practices added in under twelve months.

Chief executive Bill Becknell has said he expects the opportunity to keep expanding, with independent practices continuing to look for support and for the benefits of scale. Mortenson expects to keep affiliating in 2026.

Now the wider context, which matters more than most owners realize.

The organizations doing the most deals in dentistry are not the ones with the largest advertising budgets.

Industry analysis of the buyer pool finds the mid-market platforms in the 200-to-500-office band completing far more affiliations each year than the household names. Mortenson is named among that group.

Of the three largest DSOs in the country, only Heartland Dental is substantially acquisition-led. Aspen Dental and PDS Health grow primarily by opening new offices.

So if you have been assuming the biggest brand you know is your most likely buyer, that assumption is probably wrong.

What “no private equity sponsor” actually changes

This is where I want to be careful, because it is easy to oversell in either direction.

Start with what it does not change. Mortenson still runs a diligence process.

It still has a board that approves deals.

It still values your practice against the same economics every other acquirer uses. The absence of a sponsor does not make anyone a soft touch.

What it does change is the clock.

A sponsor-backed organization is generally working toward a recapitalization. That is the moment the sponsor sells or refinances and everyone’s paper gets marked.

Survey work reported by Becker’s puts a large majority of DSOs anticipating a recap within roughly one to three years. That event is why rollover equity in a sponsor-backed deal can be so valuable.

It is also why the timing is not yours to control.

An employee-owned organization has no such event scheduled. That is a genuinely different shape of risk, and it is neither better nor worse in the abstract.

It is only better or worse for you, depending on what you want.

If what you want is a second payout at a recap, a sponsor-backed structure is built to deliver exactly that. The arithmetic can be excellent.

If what you want is a stable long-horizon home for your team, with nobody optimizing toward a sale window, that argues the other way.

Here is the part owners consistently skip. ESOP shares have no public market.

Their value is established by periodic independent valuation, not by a ticker, and distributions follow retirement-plan rules rather than deal terms.

None of that is a criticism. It is true of every ESOP in the country, in every industry.

It simply means the question “what is my equity worth and when can I touch it” has a different answer here. Get that answer in writing before you sign anything.

One more thing worth separating in your head. Automatic ESOP participation is described as an employment benefit for team members, and eligible doctors can purchase stock.

That is a distinct question from how your purchase price is structured. Do not assume the two are the same conversation.

Ask both.

The pace, and what a practised process buys you

An organization completing several affiliations a year, every year, is not making it up as it goes.

Mortenson publishes its process. Six stages, in order.

Stage one, initial exploration. Informal conversations, for as long as everyone needs. No documents.

Stage two, evaluation and NDA. A non-disclosure agreement, a visit to your practice, and a request for several financial documents.

Stage three, valuation and letter of intent. They analyze the practice, arrive at a valuation, negotiate, and execute a non-binding letter of intent.

Stage four, executive approval. The executive leadership team and board sign off. Legal completes remaining diligence.

Integration planning starts here.

Stage five, binding documents. A binding letter of intent, then the definitive documents for closing.

Stage six, integration. You, your team and your practice move across.

Read that as an owner and the practical benefits are obvious. They have done this dozens of times.

The document request list is settled. The lawyers know their own forms.

Nobody is inventing a structure on your deal at midnight.

Speed is real value. Deals die from drift far more often than from disagreement, and a counterparty who has closed twenty of these does not drift.

Now the honest counterpoint, which applies to every repeat acquirer in this market and singles nobody out.

A process refined across dozens of transactions is refined around the acquirer’s requirements as much as yours. That is not cynicism; it is just where the repetitions happened.

The template exists because it worked — for the party who wrote it, twenty times running.

Standard terms are terms someone else drafted.

Which brings us to the only reliable mechanism for changing that. A repeat acquirer departs from its own template when there is a reason to.

Competition is the reason. Nothing else moves a settled form as reliably, because nothing else changes what the deal costs them to lose.

What kind of practice Mortenson looks for

Their own affiliation materials are unusually plain about the cultural filter. They describe wanting practices that are passionate about delivering high-quality care without private equity involvement, and owners who want to give their team a rewarding career as owners.

Take that at face value. It is a screen, and it screens both ways.

Geographically, the pattern is density rather than flag-planting. The West 10th deal is the clean illustration: Mortenson already supported thirteen Indianapolis practices to the north, south and east, and West 10th’s locations sat to the west.

That is a gap-filling acquisition. Those are the ones a regional acquirer pays most attentively for, because the operating benefits are immediate and local.

The West 10th multispecialty hub was explicitly part of the appeal — a single location delivering orthodontics, periodontics, oral surgery, pediatric dentistry and endodontics alongside general care.

Structurally, Mortenson operates as a family of regional brands rather than one national banner. Eleven of them, by its own listing.

They are Mortenson Family Dental, Gentle Dentist, Howard Family Dental, Stonehaven Dental, Summit Dental Health, Abbeville Dentistry, West 10th Dental Group, Kid’s Dentistree, American Family Orthodontics, Advanced Dental Solutions and Oral & Facial Surgery Group.

Practically, that means a fit question you can answer before the first call. Does your practice sit inside or adjacent to one of those regions?

If yes, you are a more interesting target than your production alone suggests.

What an offer typically contains

Mortenson does not publish a price sheet, and neither does any other organization in this market. What a buyer pays depends on the practice, the geography, their current appetite, their capital position, and above all on who else is bidding.

Any source quoting you a specific multiple for a named organization is generalizing from limited data. Treat it accordingly.

What does hold broadly across the buyer pool, rather than for any one organization:

Cash at close is typically a portion of the headline figure, not all of it.

Rollover equity — keeping a slice of ownership in the buyer’s company instead of taking all cash — often makes up part of the balance.

Earnout, meaning part of the price paid later and only if agreed targets are hit after closing, may account for the rest.

Two offers with identical headline numbers can be worth materially different amounts. That is the whole reason a headline number tells you almost nothing.

The bridge most dental owners get wrong

Before any of that matters, you need the right number to apply it to. Dental owners think in collections and overhead percentage.

Acquirers think in EBITDA. These are not interchangeable, and the gap between them is where a great many owners lose money.

Walk it once, properly.

Start with collections — the money actually collected, not what was billed or produced. Say $3.1 million.

Subtract true operating overhead. At a 62% overhead ratio, that is $1.92 million, leaving $1.18 million.

Now the step owners skip. Subtract what it would cost to pay a market-rate associate to do the clinical work you currently do yourself.

If you personally produce $1.1 million and the market rate is 30%, that is $330,000.

You are left with roughly $850,000 of adjusted EBITDA. That is the number an acquirer is actually buying.

Now apply the credible 2026 ranges. Very approximately: 5 to 7 times for a solo general practice bought as a tuck-in, 7 to 9 times for a two-to-four-doctor group taken on as a regional add-on, 8 to 11 times for a five-to-nine-location regional group.

A single-location practice at $850,000 therefore lands somewhere near $4.3 million to $6.0 million before structure.

Now watch what happens to the same practice under the other framing. Someone quotes you “85% of collections.” On $3.1 million that is $2.64 million, and it sounds like a real number because it is expressed in the units you think in every day.

It is roughly three times EBITDA. It is not remotely the same offer.

I have sat across from owners who were genuinely pleased with a percentage-of-collections figure and had no idea what it converted to. Nobody misled them.

They simply never did the conversion, and the conversion is the entire game.

What changes after the sale

Branding is the question owners ask first, and the honest answer here is that it depends.

Milford Dental Clinic and Fallbrook Family Dentistry were rebranded as Summit Dental Health when they affiliated. West 10th Dental Group kept its name and now sits in the group listing as its own brand.

Both outcomes are real. Both happened within seven months of each other.

So the practical instruction is simple: ask, get the answer in writing, and do not infer it from what happened to a practice down the road.

On the team side, Mortenson’s stated model is that team members are automatically enrolled in the ESOP at no cost. That is a genuinely different pitch to make to your staff than most acquirers can offer.

Its published doctor retention rate is above 90% and hygiene retention above 85%.

Those are the organization’s own figures. They are also the kind of figures worth testing against people rather than pages.

On your own role, the support-center model is standard for the category — marketing, IT, credentialing, human resources and accounting handled centrally, with the clinical work left to you.

The terms genuinely worth pinning down in writing, at any acquirer: which clinical decisions stay with you, your post-sale role and hours, what happens to your team’s roles and pay, whether your practice name survives, and who your day-to-day contact becomes.

Questions worth asking Mortenson specifically

Some of these apply to any acquirer. Several only make sense here.

Can I speak with two dentists who affiliated at least two years ago? Two years is long enough for integration to have finished and any honeymoon to have ended.

A confident organization arranges that call quickly. Hesitation, or a single carefully chosen reference, tells you something at no cost.

Which regional brand does my practice go into, and does my name change? Given that both answers exist in their own recent history, this is not a rhetorical question.

How is ESOP stock valued, how often, and by whom? Independent valuation is standard. The cadence and the methodology are what you actually want to know.

When can I access the value of any stock I hold? Retirement-plan distribution rules govern this, not deal terms. Find out the practical timeline for someone in your position and at your age.

How does my purchase price interact with ESOP participation, if at all? These may be two entirely separate things. Get that confirmed rather than assumed.

Without a sponsor recapitalization on the horizon, what is the liquidity path for any equity in my consideration? A fair question, asked neutrally, and any serious acquirer will have a clear answer.

Which parts of your standard agreement have you changed for other sellers? This one is worth asking any repeat acquirer. The answer tells you exactly where the template is soft.

How to know whether the offer is competitive

Here is what actually decides your outcome, and it is not which organization is on the letterhead.

An acquirer who approaches you directly is competing with nobody. The offer reflects that, and it would be strange if it did not.

The same organization, bidding against three others who also want your practice, behaves differently. Not because the first number was dishonest.

Because the leverage changed.

The pool is deep enough for that to be real. Becker’s Dental Review tracked more than 200 DSO affiliations across the United States in 2025, and reported that 69% of DSOs expect increased acquisition activity in 2026.

Roughly 30 to 35 organizations acquire independent general practices at meaningful scale.

The demographics point the same way. ADA Health Policy Institute data shows practice ownership among US dentists falling from 84.7% in 2005 to 72.5% in 2023, while DSO affiliation reached 16.1% of dentists in 2024 and 27% among those within five years of graduation.

Fewer independent practices exist each year. That is your side of the table talking.

And regional platforms frequently outbid national ones inside their own footprint. Filling a gap in a market they already run delivers density and shared-cost benefits immediately.

A scattered national addition delivers none of that.

Creating that competition is what the Elite Selling System exists to do. We hand-select and vet every buyer who bids, the way a doorman with a velvet rope admits only the right people.

Then we run a private competitive window.

Against a repeat acquirer with a settled process, this is the whole argument. Competition is what makes a practised buyer depart from a template they have used twenty times without ever needing to.

What to do next

If a Mortenson approach is in front of you, the first job is not to judge it against your expectations. It is to convert it into something you can actually compare.

Get your adjusted EBITDA documented — what the practice earns after paying a market-rate dentist to do the work you currently do yourself.

Separate the cash at close from anything deferred or held as equity. Then find out what your practice attracts when several qualified organizations are competing for it.

The ownership model here may genuinely suit you. It is a serious option for an owner who cares where their team lands, who is uneasy about a sale window set by someone else, and who wants a buyer with long institutional memory in their region.

Choose it on the numbers, though. Not on the framing, and not because the first approach happened to arrive first.

We will give you that assessment free and in confidence, including the answer that you should wait and fix a few things first when that is the honest one. It starts with a free, confidential practice value estimate.

Our fee varies depending on the value of the practice and is entirely success-based. If we do not get you a result, we do not get paid.

Frequently asked questions

Does Mortenson Dental Partners buy dental practices?

Yes. Mortenson completed five acquisitions in 2025 and its supported-practice count has moved from 144 in March 2025 to 156 today.

Its chief executive has said the organization expects to keep affiliating through 2026.

Is Mortenson Dental Partners private-equity-backed?

No, according to its own disclosures. Mortenson states that it is 100% dentist and employee owned through an employee stock ownership plan, with zero private equity.

That is unusual for an organization supporting more than 150 practices.

What is an ESOP, and why does it matter to a seller?

An employee stock ownership plan is a qualified retirement plan invested primarily in the employer’s own stock, as the IRS defines it. For a seller it matters because no sponsor recapitalization sits on the horizon.

That changes the timing and shape of any equity.

How many practices and states does Mortenson Dental Partners cover?

It reports 156 supported practices and more than 2,500 team members. Its own materials name ten states: Kentucky, Indiana, Ohio, Utah, Iowa, Nebraska, Texas, Missouri, Georgia and South Carolina.

Will my practice keep its name?

It depends, and both answers have happened recently. Milford Dental Clinic and Fallbrook Family Dentistry were rebranded to Summit Dental Health in 2025, while West 10th Dental Group retained its name as its own brand.

Get the answer in writing.

What does Mortenson Dental Partners pay for a practice?

There is no published price sheet, and any specific multiple attached to a named organization is generalized from limited data. What any acquirer pays depends on the practice, the market, their current appetite, and who else is bidding.

Are the biggest DSOs the most likely buyers for my practice?

Usually not. The mid-market platforms in the 200-to-500-office band complete the most affiliations per platform, and of the three largest DSOs only Heartland Dental is substantially acquisition-led.

Should I accept a direct offer from Mortenson?

Not before other qualified buyers have bid. An acquirer with a well-practised process has a settled set of terms for a reason, and competition is the mechanism that gets those terms opened up rather than presented.
