Four Phases Of A DSO Dental Practice Sale
The DSO dental practice sale process follows four phases.
-
Preparation And Valuation. The preparation and quality-of-earnings (QoE) phase typically runs 6 to 8 weeks (weeks 1–8). The seller assembles financials, a CPA-led EBITDA analysis is built, and the practice is positioned for market. The seller’s main obligation is providing access to financial records and practice management software.
-
Marketing And Competitive Auction. Typically 45–60 days. A marketing deck and virtual data room are created, and a structured bid process is run among vetted buyers. The seller’s main obligation is participating in buyer meetings while the advisor manages the competition.
-
Due Diligence And Negotiation. Typically 60–90 days. The winning buyer conducts a quality-of-earnings review, and the letter of intent (LOI) and deal structure are negotiated. The seller’s main obligation is producing documentation and defending the EBITDA that was presented.
-
Closing And Transition. The closing and transition phase typically takes four to eight weeks post-close to fully stabilize operations under new ownership, though full integration of billing, scheduling, and reporting systems can take 6 to 12 months. The asset purchase agreement, employment agreement, and management services agreement are executed. The seller’s main obligation is negotiating the employment agreement and completing the legal close.
The full DSO dental practice sale process typically runs about 6–9 months from preparation through closing, consistent with industry reporting on DSO transaction timelines. The competitive auction phase itself typically runs 45–60 days. Leverage is highest before the owner signs anything exclusive and declines steadily once an LOI is signed. Dental attorneys often advise treating the LOI as if it were a binding contract, because terms not addressed in it tend to be resolved in the buyer’s favor.
Phase 1 — Preparation And Valuation: How Adjusted EBITDA Is Built
The financial foundation must be established before a practice goes to market. This phase covers financial cleanup, add-back documentation, and a CPA-led EBITDA analysis.
Adjusted EBITDA is earnings before interest, taxes, depreciation, and amortization, normalized to reflect what the practice could earn under new ownership. A DSO applies a multiple to this figure to arrive at enterprise value. It starts with net income, then adds back expenses that would not continue under new ownership.
Common add-backs include:
-
Owner compensation above what a market-rate replacement associate dentist would cost
-
Personal and discretionary expenses run through the practice, such as personal vehicles, family payroll above market, and non-clinical travel
-
Non-recurring items such as one-time legal fees or equipment purchases
-
Standard non-cash charges like depreciation and amortization
Owner compensation normalization is often the single largest EBITDA adjustment and the most frequently contested in a quality-of-earnings review. The difference between what an owner actually takes home and what a market-rate associate would cost can represent 30–50% of a practice’s total EBITDA.
The key distinction is between add-backs that survive scrutiny and those that do not. Universally accepted add-backs include depreciation, amortization, interest expense, and owner health insurance premiums. Buyers often challenge add-backs such as personal vehicle expenses, family member compensation above market rate, one-time legal or consulting fees, and above-market rent on seller-owned buildings.
Every soft add-back must be supported by tax returns, market-rate compensation surveys, independent lease comparables, or receipts with business justification, because the burden of proof sits with the seller.
A diligence-grade, CPA-led valuation holds up in a quality-of-earnings review. A free, back-of-the-napkin number often becomes the anchor that quietly sets what the owner walks away with. McLerran & Associates has documented this directly: a free valuation pegged one practice at $2.5M; McLerran valued it at $4.5M and it sold for $5.25M after a competitive process. For owners weighing both paths, McLerran produces a side-by-side valuation quantifying worth in both the private-buyer and DSO markets.
Seller’s Leverage Point: This is where the narrative around profitability is set. An owner who controls the EBITDA story here can defend it later in diligence. One who does not often gets re-traded. With that foundation in place, the practice is ready to go to market.
Request a CPA-led valuation to anchor your EBITDA story.
Phase 2 — Marketing And The Competitive Auction
Once the valuation is established, the practice goes to market through a structured, auction-like bid process. McLerran builds a marketing deck and a virtual data room, which is a curated repository of everything worth showcasing, and solicits offers from a vetted pool of well-qualified DSO and private equity buyers. This process typically runs 45–60 days and often generates around 10 offers, narrowing to 1–3 finalists who participate in in-person meetings or headquarters visits.
Responding to a single unsolicited DSO offer is a different negotiation entirely. The owner faces one buyer, with no competitive tension, against a counterparty that negotiates deals every week. A competitive sales process can improve total transaction value meaningfully over an unsolicited offer. The spread between an unsolicited offer and a negotiated deal can be substantial. McLerran vets buyers and has blacklisted DSOs known for poor post-close environments, so poorly run buyers never reach the table.
McLerran clients typically see around a 30% higher valuation than owners achieve selling on their own, and the firm reports a transaction rate of roughly 85–90% versus an industry norm closer to 35–40%.
Seller’s Leverage Point: Competitive tension is the single biggest price lever in the DSO dental practice sale process. It exists only if more than one qualified buyer is at the table simultaneously.
Phase 3 — Due Diligence, Quality Of Earnings, And Deal Structure
After an LOI is signed, the buyer conducts formal due diligence. The centerpiece of this phase for DSO transactions is a quality-of-earnings (QoE) review, which is an independent accountant’s examination of whether the EBITDA the seller presented is real, sustainable, and correctly adjusted. Quality-of-earnings diligence has become standard for dental transactions above roughly $2M in EBITDA, and seller-paid sell-side QoE reports have become more common as sellers seek to shorten diligence timelines and reduce post-LOI surprises.
McLerran defends the EBITDA it underwrote when the buyer’s QoE team challenges add-backs, and reminds buyers that other vetted bidders remain available if they attempt to re-trade the deal down. This can be a meaningful protection. A practice’s adjusted EBITDA may show one figure, but if soft add-backs cannot survive documentation review, the defensible number can be materially lower. At a typical multiple, each dollar of EBITDA lost translates to several dollars of enterprise value lost.
Deal structure is also negotiated during this phase, and the mechanics matter as much as the headline number. DSO purchase prices typically combine three elements, each with different risk and liquidity profiles:
-
Cash At Close. Cash at close typically falls in the 60%–80% of headline enterprise value band for lower-middle-market and platform DSO transactions.
-
Rollover Equity. As much as 40% of a DSO deal can be paid in equity rather than cash. That equity can sit at the joint-venture (JV) level, where the seller retains a stake in their specific practice entity and receives distributions. JV equity has a higher floor but a lower ceiling. Alternatively, it can sit at the holding-company level, where the seller holds equity in the DSO’s parent platform. That equity pays no distributions but offers a higher potential ceiling if the platform is later resold at a higher multiple. DSO rollover equity is almost always structured as an interest in a private entity and cannot be sold until the DSO achieves a liquidity event, typically within a 5–7 year hold period.
-
Earnout. Earnouts in DSO dental deals are contingent payments tied to the practice hitting financial targets typically 1–3 years post-close. If the DSO controls expenses, headcount, and pricing after acquisition, the buyer effectively controls whether the seller’s earnout target is achievable. Non-punitive earnout terms, such as pro-rata provisions so a near-miss on an EBITDA target still pays most of the earnout, and later start dates to account for integration, are negotiable at the LOI stage and rarely later.
Because these three elements carry different risks, comparing offers that look similar on the surface requires modeling the full economic picture. A higher headline number with a large equity component and a punitive earnout can be worth less than a slightly lower, mostly-cash offer. McLerran models multi-year, multi-structure outcomes over 3-, 5-, 7-, and 10-year horizons, conservatively assuming one recapitalization in years five to seven, so owners compare real after-tax proceeds rather than headline numbers.
On tax treatment, much of a DSO deal, specifically the goodwill component, is typically treated at long-term capital gains rates rather than ordinary income. On a $3M dental practice sale, every $100,000 shifted from non-compete allocation (taxed as ordinary income) to goodwill allocation (taxed at capital gains rates) can produce meaningful federal tax savings. Readers should consult their own tax advisors on their specific situation.
Seller’s Leverage Point: The LOI stage is where structure is won or lost. Non-punitive earnout terms are negotiable here and rarely later. Once a dental practice owner signs an LOI, they will almost certainly be required to agree to an exclusivity period, typically 60–120 days, during which they cannot solicit or entertain offers from other buyers.

Phase 4 — The Employment Agreement, Closing, And Post-Close Transition
The employment agreement is a separate negotiation from price and is often the most underestimated part of the DSO dental practice sale process. The most common mistake dental sellers make is negotiating the purchase price without simultaneously negotiating the transition employment agreement. A $3M purchase price with a 3-year below-market employment agreement can be worth less than a $2.5M purchase price with a market-rate employment agreement.
Key employment agreement terms to negotiate include:
-
Work-Back Period. Most DSO transactions include a 3–5 year employment agreement for the selling dentist, with compensation typically structured as a percentage of net collections.
-
Compensation. Go-forward compensation for general dentistry is typically structured at 30–35% of net collections, while specialty work commands higher rates. Whether compensation is based on production or collections matters. Production is generally more seller-favorable.
-
Clinical Autonomy. Clinical autonomy is preserved in most DSO transactions in the sense that treatment planning decisions remain the responsibility of the treating dentist. Staffing decisions, scheduling templates, software platforms, and supply vendor relationships are typically standardized across a DSO’s portfolio.
-
Non-Compete Terms. Non-compete terms commonly run three years, with five years being the buyer’s opening ask. The geographic radius should match the practice’s actual patient draw rather than the entire metro area.
-
Termination Provisions. Sellers should confirm what happens to their earnout, rollover equity, and non-compete obligations if the buyer terminates them without cause mid-employment term.
Closing mechanics involve the asset purchase agreement, the handoff of staff and patients, and, in most states, a management services agreement (MSA) structure under which the DSO acquires non-clinical assets while the dentist retains ownership of the professional corporation holding the dental license. McLerran serves as buffer and advocate through closing, including introductions to attorneys and lenders, though McLerran is not the attorney.
One forward-looking consideration deserves attention: what happens if the DSO is later resold or recapitalized? A DSO recapitalization is a platform-level capital event that resets ownership of the dental support organization without selling the individual practices underneath it. It is also the moment rollover equity becomes liquid. In a recapitalization, the dentist may be required to roll some equity again into the new holding structure, potentially extending the illiquidity period.
Because as much as 40% of a deal can be in equity, the owner is effectively underwriting the DSO as an investment. The value of retained equity depends directly on the buyer’s strength and backing. Its profitability, growth at existing offices, management experience, and private equity sponsor’s track record all determine whether that equity is worth what the seller hopes.
Seller’s Leverage Point: Post-close economics depend on buyer quality chosen months earlier. Fit and financial strength can matter as much as headline price.
How Long Does It Take To Sell A Dental Practice To A DSO?
As outlined in the four phases above, the full process typically runs about 6–9 months. The competitive auction phase usually occupies 45–60 days, and diligence and closing consume the balance.
The timeline can shift based on the readiness of financials at the outset, the number of qualified buyers engaged simultaneously, the complexity of the deal structure, particularly the equity and earnout components, and how quickly the employment agreement is negotiated. Decision checkpoints where a seller can still walk away include before signing any exclusivity agreement, before signing the LOI, and during diligence if the buyer attempts to re-trade the agreed price. For owners weighing whether to pursue a DSO sale at all, the next section compares the DSO path with a traditional doctor-to-doctor sale.
DSO Sale Vs. Private Sale Process: Key Differences For Owners
The table below compares the two paths on the dimensions that most affect an owner’s economic outcome: buyer profile, valuation method, work-back period, and post-close obligations. The key takeaway is that DSO deals often offer higher headline prices but come with employment agreements and illiquid equity, while private sales tend to offer cleaner exits at lower valuations.

Owners in the roughly $1.5M–$3M revenue range can genuinely go either way, which is why McLerran’s side-by-side valuation matters. It quantifies worth in both markets before the owner chooses a path.
Frequently Asked Questions
How Long Does The DSO Dental Practice Sale Process Take?
The process typically runs about 6–9 months from preparation through closing. The competitive auction phase itself typically runs 45–60 days. Variables that can extend the timeline include the readiness of financial records, the complexity of the deal structure, and the pace of employment agreement negotiations. Doctor-to-doctor sales typically close faster, in roughly 4–6 months.
How Is Adjusted EBITDA Calculated And Defended In A DSO Sale?
Adjusted EBITDA starts with net income and adds back the owner’s compensation above what a market-rate replacement associate dentist would cost, personal and discretionary expenses run through the practice, non-recurring items, and non-cash charges like depreciation and amortization. The resulting figure is what a DSO applies a multiple to in order to arrive at enterprise value. Defending it requires documentation for every add-back, including tax returns, market-rate compensation surveys, and receipts with business justification. Add-backs that lack documentation are challenged or rejected during the buyer’s quality-of-earnings review, which can reduce the defensible EBITDA figure and, at a typical multiple, meaningfully reduce the final sale price. McLerran builds a diligence-grade, CPA-led EBITDA analysis up front so the number holds when buyers scrutinize it.
What Is A Quality-Of-Earnings Review?
A quality-of-earnings (QoE) review is an independent accountant’s examination of whether the EBITDA a seller presented is real, sustainable, and correctly adjusted. The buyer’s QoE team reviews tax returns, practice management software reports, bank reconciliations, and production reports by provider, then challenges any add-back that lacks documentation. QoE has become standard on DSO transactions above roughly $2M in EBITDA. McLerran defends the EBITDA it underwrote during this process and reminds buyers that other vetted bidders remain available if they attempt to re-trade the agreed price.
Are DSO Deals All Cash, Or Do They Include Equity?
DSO deals almost always use a mix of cash and equity, and sometimes an earnout. As noted in the deal structure section, cash at close typically represents 60%–80% of total deal value, with the remainder in rollover equity and occasionally an earnout. That equity can sit at the joint-venture level, where the seller retains a stake in their specific practice entity and receives distributions, or at the holding-company level, where the seller holds equity in the DSO’s parent platform with no distributions but higher potential upside if the platform is later resold at a higher multiple. Because rollover equity is illiquid and its value depends on the DSO’s future performance, McLerran helps owners underwrite the DSO like an investment before accepting equity as a meaningful portion of proceeds.
Does The Selling Dentist Have To Keep Working After The Sale?
On a DSO deal, yes, the 3–5 year employment agreement noted earlier is standard. The selling dentist transitions from owner to employed clinician, typically compensated as a percentage of net collections. The degree of clinical autonomy, schedule flexibility, and non-compete scope vary by buyer and are negotiable. On a doctor-to-doctor walk-away sale, the seller typically works back only about 4–8 weeks before exiting. McLerran negotiates employment agreement terms on the owner’s behalf alongside the purchase price, because the two together can determine the real economic outcome.
How Do I Tell A Good DSO From A Bad One?
Vetting buyers is a core part of McLerran’s mandate. Key factors include the DSO’s profitability and same-store growth at existing offices, the management team’s experience, the private equity sponsor’s track record of successful exits, and references from dentists who sold to the same platform several years ago. McLerran has blacklisted DSOs known for poor post-close environments, including undercapitalized buyers that emerged when capital flooded the space, so poorly run buyers never reach the table. Owners should also ask what happens to their rollover equity if the DSO is recapitalized or resold, and request a cap table and distribution waterfall before signing.
What Happens To Staff And Patients After The Sale?
In most DSO acquisitions, existing staff are retained as part of the deal because the team represents institutional knowledge and patient relationships that are part of what the buyer is acquiring. Staff employment agreements are typically restructured under the DSO’s employment framework, including its benefits programs and HR systems. For patients, the selling dentist typically continues practicing under a 3–5 year employment agreement, so patients usually keep seeing the same doctor for years. Finding the right fit is half of McLerran’s mandate, not just the highest price, and the firm aims to secure a strong financial outcome while identifying a buyer whose strategy and support model protect the legacy, patients, and staff the owner leaves behind.
Is Now A Good Time To Sell?
Demand remains steep for premier, Class A practices and valuations sit near all-time highs. McLerran will tell owners candidly how their specific practice is positioned, and if an owner is not ready, the firm will update the valuation for free a year later rather than push anyone into a deal before the time is right.

Conclusion And Next Steps
Across all four phases, the same principle applies: leverage is highest before exclusivity and declines with every signature. Owners who capture the most value typically build a defensible EBITDA story, create competitive tension, negotiate structure alongside price, and vet the buyer as carefully as the buyer vets them.
McLerran & Associates is sell-side only, dental-only, works both transition paths in roughly equal measure, and has completed approximately 2,000 practice sales with the transaction rate noted earlier.
Concrete next steps for any owner considering a transition include assembling 3 years of financial records, clarifying personal goals and timeline, requesting a comprehensive valuation, and speaking with a dental-specific sell-side advisor before responding to any unsolicited DSO offer. Engaging with a DSO directly, without competitive tension or representation, shifts the leverage to the buyer’s side of the table.
