Key Takeaways

• California medical corporations must be at least 51% owned by licensed physicians under Cal. Corp. Code § 13401.5. The physician-partner is not a medical director on a stipend arrangement — the physician holds actual shares of the professional corporation.
• The physician-partner search is often the hardest single step of remediation. Physicians who take on the shareholder role take on personal Medical Board exposure, professional liability exposure, and the substantive clinical authority the role requires. The compensation and terms have to reflect all three.
• Common physician-partner sourcing paths: the current medical director (if willing to transition from paper role to substantive one), specialists in the modality (emergency medicine, family/internal medicine, psychiatry, functional medicine, integrative medicine), retiring physicians looking for a second act, and physicians with prior operator relationships in adjacent practices.
• Terms to negotiate: compensation (both for shareholder role and for services actually rendered), buy-sell mechanics (how the shares transition if the physician wants to exit), medical director scope, clinical authority and decision-making, MSO relationship boundaries, and change-of-control provisions.
• Two common mistakes: negotiating shareholder terms so restrictive that the physician has no real authority (which the California AG’s 2026 enforcement pattern has publicly targeted as “captive PC” arrangements), and negotiating terms so favorable to the physician that the operator loses meaningful economic participation. The compliant structure balances physician authority with legitimate operator economics.

How to Add a Physician-Owner to Your California Treatment Business

Every California CPOM remediation depends on a physician willing to hold at least 51% of a professional medical corporation on terms the non-licensee owner can live with. The professional corporation is the load-bearing structural component of the friendly-PC + MSO model, and the physician-partner is the load-bearing personal component of the professional corporation. Without the physician-partner, the remediation cannot go forward. With the wrong physician-partner, the remediation goes forward but produces a structure that will not survive scrutiny.

This post walks through what the physician-partner search, terms, and structure actually look like in practice. It sits under the remediation pillar for the CPOM Acquisition & Remediation cluster and pairs with the LLC conversion and historical liability posts in this same batch.

Why This Is the Hardest Step

Remediation converts a non-compliant LLC or non-physician corporation into a friendly-PC + MSO structure. Every structural piece can be built by counsel. The MSA can be drafted. The PC can be formed. The clinical asset transfer can be executed. The billing and marketing infrastructure can be reconfigured.

What counsel cannot build is a physician willing to be the shareholder. That has to come from the physician’s own decision to accept the role — with all of its exposure, compensation, and clinical authority implications. And unlike the paper medical director role that many California practices have relied on for years, the compliant physician-partner is genuinely engaged in the clinical direction of the practice. That is a substantially different commitment than a monthly stipend for signing standardized procedures.

For most non-licensee owners approaching remediation for the first time, the physician-partner search takes longer than anticipated, requires more compensation than the operator initially wants to offer, and involves more clinical authority than the operator initially wants to yield. All three of those are features, not bugs, of the compliant structure.

Where Physician-Partners Come From

Four common sourcing paths, in rough order of ease:

1. The current medical director (transitioned to a substantive role). If the practice has a current medical director who has been on retainer, and the medical director has the appropriate specialty background and is willing to take on genuine clinical authority, transitioning the current medical director into the physician-partner role is often the smoothest path. The physician already knows the practice, the patients, the staff, and the operational rhythm. The negotiation is around whether the physician is willing to move from paper role to substantive role, and whether the compensation and clinical authority match the new engagement.

The candid conversation with the current medical director is where this path either works or doesn’t. Some medical directors have taken on the paper role explicitly because they didn’t want a substantive engagement — they wanted the stipend and were comfortable with the risk profile of the arrangement. Those medical directors are unlikely to want the shareholder role. Other medical directors have been in the paper role because that was what was on offer, and would prefer a genuine engagement with the practice if the terms make sense. Those medical directors are candidates.

2. Specialty-appropriate physicians identified through professional networks. For hyperbaric, IV, ketamine, GLP-1, and HRT practices, the physician-partner needs a specialty background that supports genuine clinical evaluation and supervision of the practice’s services. Physician recruiting firms, healthcare consulting firms, medical staff at adjacent hospital systems, and modality-specific professional societies are typical sourcing channels. The recruiting timeline is often measured in months rather than weeks, and the compensation expectations of specialty physicians willing to take on the shareholder role tend to be substantially higher than what a paper medical director stipend would have supported.
3. Retiring or semi-retired physicians looking for a second-career engagement. Physicians in the later stages of hospital-based or full-time clinical careers sometimes look for lower-intensity engagements that keep them clinically active without the demands of full clinical practice. The shareholder role in a well-run friendly-PC structure can fit this profile — clinical authority without the day-to-day demands of primary patient care. The recruiting channels here are professional network referrals, healthcare consulting firms with retirement-transition practices, and (in some markets) medical staff office referrals.
4. Physicians with prior operator relationships. A less common but occasionally attractive path — physicians who have previously served as the physician-partner in similar structures for other operators. The physicians are familiar with the compliant structure, understand the MSO relationship, and have experience negotiating the shareholder terms. The trade-off is that experienced physician-partners tend to command experienced-partner compensation, and their portfolios may already include multiple structures.

Practices that combine two or more of these sourcing paths — starting with the current medical director conversation, in parallel with a network search, typically close the physician-partner recruitment fastest.

What the Compensation Structure Typically Looks Like

The physician-partner receives compensation for three distinct roles. Each has its own analytical framework and its own fair-market-value considerations.

Compensation for the shareholder role. As the shareholder of the professional corporation, the physician receives the equity economics of the PC. Depending on how the friendly-PC + MSO structure is set up, this can range from a nominal amount (the PC’s economic upside flows to the MSO through the management fee) to a substantial amount (the PC retains meaningful economic value and the shareholder participates). The structure has to be arm’s-length and defensible against the AG’s 2026 enforcement pattern — an assignable option that gives the MSO the right to reacquire the shares was one of the arrangements the Carbon Health settlement specifically identified as impermissible.

Compensation for clinical services rendered. The physician’s actual clinical work — good-faith exams conducted, charts reviewed, standardized procedures developed and approved, incident management, being immediately available during procedures — is compensated separately. This can be a salary, an hourly rate, per-service rates, or a hybrid. The compensation should track services actually rendered and should reflect fair-market rates for physician time at the specialty and experience level involved.

Compensation for the medical director role. Where the physician-partner also serves as the medical director (the common configuration), the medical director role has its own compensation. This can be bundled with clinical services compensation or separated. Documentation of the medical director’s time — GFEs conducted, charts reviewed, standardized procedures signed, incident management logs — supports both the compensation arrangement and the compliance posture.

The specific numbers vary widely by modality, region, and physician profile. Ranges anywhere from $150,000 to $500,000+ per year across the three roles are common for California friendly-PC arrangements at various scales. What is not compliant — and what the California AG’s 2026 enforcement pattern has specifically targeted, is a token stipend for the shareholder role paired with an MSA that sweeps most of the PC’s revenue to the MSO. The compensation has to reflect the substantive role the physician actually plays.

Terms Beyond Compensation

Beyond compensation, several terms are load-bearing for compliance and for a workable long-term relationship:

Buy-sell mechanics. How does the physician’s ownership transition if the physician wants to exit? What if the physician dies, becomes disabled, or has their license restricted? What if the operator wants to bring in a different physician-partner? The buy-sell provisions in the shareholder agreement have to preserve § 13401.5 shareholder eligibility (any share redemption or transfer has to go to another licensed physician), have to comply with the § 13407 void-transfer rule (no non-licensee can ever hold the shares), and — critically — have to avoid the arrangements the AG’s Art Center Holdings amicus brief and Carbon Health settlement specifically identified as impermissible. Provisions that give the MSO the right to trigger replacement of the physician-owner without cause, assignable options to acquire the shares, and mechanisms that give the MSO effective control over physician succession are the specific structures the AG has publicly labeled impermissible.

Medical director scope and clinical authority. The physician’s clinical authority has to be genuine. The physician decides which patients receive which treatments, which clinical staff are hired and retained (subject to the practice’s HR framework), what clinical protocols apply, when to escalate clinical concerns, and how to handle clinical incidents. The MSO can provide operational support around all of these functions, but cannot dictate the underlying clinical decisions. SB 351 (effective January 1, 2026) codifies this for PE- and hedge-fund-affiliated MSOs; the underlying CPOM doctrine applies to every non-licensee-owned MSO regardless of capital source.

MSO relationship boundaries. The MSO provides non-clinical services and receives a fair-market-value management fee. The MSO does not employ clinical staff (the PC does). The MSO does not make clinical decisions. The MSO does not control patient records. The MSO does not directly bill patients for medical services (the PC does; the MSO invoices the PC for services under the MSA). These boundaries have to be clear in the operating documents and clear in day-to-day operations. The Carbon Health settlement identified specific MSO overreach — advertising authority, payor negotiation authority, equipment selection authority, clinician hiring and firing authority — that the AG considered evidence of underlying CPOM violation.

Change-of-control provisions. When the MSO’s ownership changes (which happens on the operator’s exit), what happens to the PC and to the physician’s role? A compliant arrangement gives the physician meaningful voice; a non-compliant arrangement gives the MSO the right to replace the physician for a different physician of the MSO’s choice. The Art Center Holdings amicus brief attacked the latter arrangement specifically.

Dispute resolution. Standard commercial provisions with California law and California venue. Non-compete and non-disparagement provisions applicable to the physician are governed by B&P § 16600 (which voids most employee non-competes) and, for PE/hedge fund-affiliated arrangements, SB 351 (which voids non-compete and non-disparagement provisions specifically in those arrangements). Sale-of-business non-competes under B&P § 16601 remain enforceable within specific limits.

Common Mistakes in Physician-Partner Recruitment

1. Undervaluing the physician-partner role. Operators sometimes approach the physician-partner recruitment as if it were the paper medical director role with a shareholder title added. The compensation offered reflects the paper medical director framework — a monthly stipend or hourly rate similar to what a purely paper role would command. Physicians with the appropriate specialty background and willingness to take on substantive clinical authority command materially more, and structures that offer paper-medical-director compensation for substantive-partner authority either fail to recruit or recruit physicians who won’t do the substantive work the role requires.
2. Restricting physician authority so aggressively that the arrangement is a “captive PC.” The operator wants economic control of the practice — understandably — and negotiates shareholder agreement terms that restrict the physician’s authority to make any decision without operator sign-off. The result is a structure that looks like friendly-PC on paper but functions like non-licensee ownership in operation. This is the arrangement the AG’s Art Center Holdings amicus brief and Carbon Health settlement specifically targeted. Aggressive restriction of physician authority is the exact wrong direction for compliance and creates the exposure remediation was supposed to eliminate.
3. Leaving the medical director role paper. Some remediations produce a compliant ownership structure (physician holds the shares) but leave the medical director role as paper — the physician has the shares but doesn’t actually conduct or supervise GFEs, doesn’t develop and update standardized procedures, isn’t immediately available during procedures, doesn’t manage clinical incidents. This is a partial remediation that addresses the shareholder-eligibility issue while leaving the operational CPOM issues in place. The Medical Board and BRN enforcement patterns have targeted paper medical director arrangements for years; the shareholder title doesn’t fix the underlying operational defect.
4. Skipping the physician’s independent counsel. In a well-run friendly-PC negotiation, the physician-partner has independent counsel representing the physician’s interests. This adds transaction cost and time, but it also produces a more defensible arrangement — arm’s-length negotiation, documented independent review, and terms the physician has actually understood and accepted rather than signed under pressure. Operators who resist the physician’s independent counsel are sometimes signaling that the arrangement they want the physician to accept wouldn’t survive independent review, which is itself a diagnostic finding.
5. Underestimating the timeline. From “we need to remediate our LLC” to “the physician-partner is on board and the new PC is formed” typically runs three to six months, and can run longer depending on the modality, the region, and the availability of appropriately-qualified physicians. Operators who plan for a two-week search timeline consistently underestimate the effort involved.

When to Bring Counsel Into the Physician-Partner Search

Before the search begins. Structural counsel can identify the specialty requirements, the compensation ranges, the compliance-critical terms, and the sourcing channels that fit the specific practice. Counsel can also identify red-flag terms in physician-partner discussions before the discussions harden into agreements the practice will later have to renegotiate.

Frequently Asked Questions

Can my existing medical director become the shareholder of the new PC?

Yes, if the current medical director is willing to take on genuine clinical authority (not just the paper role) and if the compensation terms work for both sides. The transition conversation is where this either happens or doesn’t. Some current medical directors want to move to a substantive engagement; others took the paper role because that was what was on offer and would prefer to stay with a paper role at other practices. The candid conversation is the diligence.

How much does the physician-partner typically make?

Ranges vary widely by modality, region, and the physician’s specialty and experience. Total compensation for the physician-partner role (shareholder equity, clinical services compensation, medical director compensation combined) commonly runs from $150,000 to $500,000+ per year for California friendly-PC arrangements at various practice scales. Practices that offer paper-medical-director-level compensation for substantive physician-partner authority consistently fail to recruit.

Does the physician-partner need to be present at the practice full-time?

No. The physician-partner’s role is defined by clinical authority and substantive engagement — GFEs conducted or supervised, standardized procedures developed and approved, clinical protocols under the physician’s authority, incident management, being immediately available during procedures. This can be structured as a full-time engagement, a substantial part-time engagement, or a distributed engagement across multiple locations depending on the practice. What is not compliant is a “physician-partner” whose actual engagement is signing paperwork monthly and being unreachable in between.

What if I can’t find a physician willing to be the shareholder?

This is a real outcome. Some remediation targets are not viable because no appropriately-qualified physician is willing to take on the shareholder role on terms the operator can accept. Where the practice cannot recruit a physician-partner, the alternatives are: (a) restructure the practice at a smaller scale that fits an available physician; (b) sell the practice to a buyer who has a physician-partner already; or (c) wind down operations. Continuing to operate as a non-compliant LLC while searching for a physician-partner extends the exposure clock.

How do the AG’s 2026 enforcement developments affect physician-partner negotiations?

The Art Center Holdings amicus brief (March 2026), Aspen Dental settlement (May 2026), and Carbon Health settlement (June 2026) collectively identified specific MSA and shareholder-agreement arrangements the AG considers impermissible: assignable options over PC ownership, exclusive above-market financing from MSO to PC, MSO authority over clinical staff hiring and firing, MSO control over advertising and payor negotiations, and continuity or succession agreements giving the MSO effective control over physician succession. Physician-partner shareholder agreements structured after these developments should be benchmarked against them — provisions that would fall on the impermissible side of the line create exactly the enforcement risk remediation is intended to eliminate.
