If you’re a dental practice owner considering a sale to a Dental Support Organization (DSO), you’re not alone. These transactions are becoming increasingly common—and increasingly complex. While the promise of liquidity, operational support, and growth is appealing, the structure of these deals can be layered and nuanced.
Here’s what you need to know about how these deals are typically structured, what documents are involved, and what life looks like after the sale.
The Anatomy of a DSO Transaction
Most DSO deals follow a hybrid structure that separates clinical operations from administrative functions. The goal is to preserve the legal independence of the dental practice while integrating it into a broader business platform.
- Asset Sale + Management Agreement. The practice sells its non-clinical assets (equipment, branding, goodwill) to a DSO-affiliated entity. The clinical entity (usually a professional corporation or professional limited liability company) remains intact and retains control over patient care. The transaction will include a Management Services Agreement (MSA), which governs the relationship, allowing the DSO to provide administrative support like HR, billing, and IT.
- Rollover Equity. Sellers often receive equity in the DSO or its parent company. This is meant to align incentives and offer upside in future recapitalizations. However, this equity is often illiquid, subject to forfeiture, and governed by restrictive agreements.
- Earnouts and Performance Bonuses. Additional payments may be tied to post-sale performance metrics such as revenue growth or patient retention. These serve the useful purposes of increasing the total potential deal value for the seller while avoiding additional capital at closing requirements for the buyer.
- Cash at Closing. A portion of the purchase price, or total transaction value, is paid upfront, typically based on a multiple of EBITDA or collections. This represents the selling dentist’s “take-home” and, therefore, represents a key component of the deal.
Key Documents You’ll Encounter
These deals are document-heavy. Each agreement plays a specific role in defining rights, obligations, and control. Typical transaction documents include:
- Asset Purchase Agreement (APA). This document defines what’s being sold, the price, and the terms of the sale.
- Management Services Agreement (MSA). This agreement outlines the administrative services provided by the DSO and preserves clinical autonomy.
- Employment Agreements. The selling doctor is typically required to work for the buyer for a minimum defined period of 3-5 years after closing. The employment agreement will govern the dentist’s post-sale role, compensation, and termination rights.
- Unitholder/Operating Agreements. These documents relate to the equity and ownership of the DSO-entities, controling the rollover equity, including transfer restrictions and exit rights.
- Shareholders’ Agreement. This agreement applies to professional entities, tying ownership to licensure and employment. PLLCs have similar agreements, often called buy-sell agreements.
- Business Associate Agreement (BAA). These documents ensure HIPAA compliance when the DSO handles patient data.
What Happens After the Sale
Selling doesn’t mean stepping away. Most dentists continue practicing under new employment terms, and most deals make this a requirement, presenting ongoing obligations for the dentist.
- Clinical Autonomy. Legally, the dentist retains control over patient care. DSOs cannot legally interfere with clinical decisions, though they may set performance expectations and will have extensive control over non-clinical aspects of the practice.
- Custodianship of Records. Patient records remain with the licensed provider. Even if the DSO provides IT infrastructure, access to clinical emails or records requires explicit authorization and must comply with HIPAA.
- Equity Liquidity Limits. Rollover equity may be non-transferable and subject to forfeiture. Exit rights are often limited to specific events like recapitalizations or retirement. Many sellers wrongly assume they’ll have control over their own exit from the DSOs. In reality, sellers often have little to no say in this decision.
- Risk of Forfeiture. Termination for cause or breach of contract can trigger mandatory buyouts at reduced valuations—or even total forfeiture of equity.
Final Thoughts: Is a DSO Sale Right for You?
Selling to a DSO can unlock new opportunities, but it’s not a one-size-fits-all solution. These deals are complex, and the long-term implications are significant. Understanding the structure, negotiating favorable terms, and planning for your post-sale role are essential.
Thinking about selling your practice?
Start by asking the right questions:
- What do I want my role to be after the sale?
- How much control am I willing to give up?
- What protections do I need in place?
A well-structured deal can be transformative, but only if it’s built on clarity, compliance, and trust.
