DSO & MSO Legal Guidance for Dental Practices in Los Angeles

These arrangements can shape how a practice operates for years. Before any agreement is signed, dentists benefit from understanding what authority they are retaining, what they may be giving up, and whether the proposed structure complies with California law. 

We help dentists identify and evaluate:

• Management authority provisions — Whether the agreement grants the management entity authority over clinical staffing, patient scheduling, or operational decisions that California law reserves for licensed dentists
• Compensation and revenue-sharing structure — Identifying financial arrangements that may raise fee-splitting concerns under California regulations governing professional practices
• Ownership and governance — Confirming that the Professional Corporation structure satisfies California’s requirements for licensed dentist ownership and control
• Restrictive covenants — Evaluating non-compete and non-solicitation clauses for enforceability and scope under current California law
• Exit rights and buyout terms — Reviewing how the agreement addresses future transitions, ownership changes, and what happens if the relationship ends
• Future change-of-control provisions — Understanding what rights you have if the DSO or MSO is sold, merged, or changes ownership after you sign

With the right review in place, dentists can enter into these relationships with a clearer picture of how the agreement will affect their practice over the long term.

A DSO generally refers to an organization that provides broad operational and administrative support to dental practices. An MSO typically structures its involvement through a management services agreement that formally separates clinical functions from non-clinical business operations such as billing, staffing support, marketing, and technology management.

In California, this structural distinction matters because state law, specifically the Moscone-Knox Professional Corporation Act,  restricts ownership and control of licensed dental practices. Only licensed dentists may own a Professional Corporation operating a dental practice in California. Management entities can provide support services under contract, but the agreement must be carefully structured so that management authority does not cross into the territory California law reserves for licensed dentists.

For dentists in Los Angeles and throughout Southern California, where DSO and MSO activity has grown significantly in recent years, understanding how these structures work legally is an important first step before evaluating any specific deal.

DSO and MSO agreements define how operational decisions are made and what authority the practice owner retains after the relationship begins. While management organizations typically handle non-clinical business functions, California law requires that clinical judgment,  including decisions about treatment, patient care, and clinical staffing, remain under the control of the licensed dentist.

The line between administrative support and clinical control is not always obvious in a contract. Some provisions that appear routine on the surface, such as patient volume expectations, staffing arrangements, or compensation structures tied to production metrics, can raise compliance concerns if they effectively give a management entity influence over decisions that California law assigns to the dentist.

California’s approach to the corporate practice of dentistry is among the most restrictive in the country. The Moscone-Knox Professional Corporation Act establishes that licensed dentists must own and control dental Professional Corporations operating in California. Management entities, whether structured as a DSO, MSO, or private equity-backed platform, can provide valuable operational support, but they cannot hold ownership interests in the PC or direct clinical operations.

For dentists in Los Angeles, Long Beach, Pasadena, and across the greater Southern California region, compliance with these requirements is not a formality. The Dental Board of California oversees licensed dentists’ conduct, and agreements that blur the line between management support and clinical control can expose dentists to regulatory scrutiny regardless of how the arrangement is labeled in the contract.

Because DSO and MSO agreements are negotiated commercial documents, their structure varies widely. Some are carefully designed to maintain a clear separation between business and clinical functions. Others contain provisions that warrant closer review. Legal analysis of the specific agreement language allows dentists to evaluate the compliance implications before committing.
