Private equity has fundamentally restructured who makes purchasing decisions in healthcare, and most healthcare B2B vendors have not caught up. Management services organizations now sit above portfolios of physician practices in dermatology, gastroenterology, ophthalmology, orthopedics, primary care, and a growing number of other specialties. The executives running those MSOs — professional managers with financial and operational training, not clinical backgrounds — control procurement for dozens or hundreds of practices simultaneously.
The healthcare vendor whose outreach strategy is built around reaching individual physicians is increasingly sending messages to people who no longer control the purchasing decision. The physician is still the clinical operator and still matters for preference-setting. But the MSO executive is the purchaser. And reaching the physician without reaching the MSO executive produces clinical awareness with no path to purchase.
This post is the complete guide to understanding the MSO executive buyer: who they are, how MSO organizations are structured, what drives their purchasing decisions, and the specific contact and messaging strategy that reaches MSO executives with content that converts.
What an MSO is and why it controls purchasing
A management services organization is a corporate entity that provides management, administrative, and business support services to physician practices under its umbrella. In PE-backed consolidation, an MSO typically sits above a portfolio of acquired practices and handles contracting, procurement, HR, billing, and financial management for all practices in the network.
The MSO structure exists to solve a specific regulatory problem: in most states, only licensed physicians can own physician practices. Private equity cannot directly own the clinical operations. The solution is a management services agreement in which the MSO provides all management services to the physician-owned clinical entity in exchange for a management fee that captures the economic value of the practice for the PE investor.
For B2B vendors, the practical effect of this structure is that purchasing authority for most non-clinical product and service categories has migrated from individual physicians to MSO executive teams. Supply chain, practice management software, billing platforms, data analytics tools, HR services, and technology infrastructure are all categories where the MSO executive is the purchaser and the physician is, at best, an influencer.
PE ownership of physician practices reached 6.5 percent by late 2024 and is expected to continue climbing through 2026, as documented in the Physician Data analysis of the disappearing physician and the healthcare buyer map shift at physician-data.com. In major metropolitan markets, a handful of MSO organizations may control purchasing decisions for a substantial share of the physician practices that vendors were previously reaching one at a time.
The MSO executive team: roles and purchasing authority
The CEO. Sets strategic direction and manages the PE firm relationship. The right contact for enterprise vendor conversations: platform agreements affecting multiple practice categories, technology investments changing the operational model, and partnership discussions involving revenue sharing or co-development. Not the right first contact for product-level introductions.
The COO or VP of Operations. Day-to-day operational leader and typically the most relevant contact for vendors whose products affect clinical operations, workflow, and practice efficiency. This role oversees practice management, staffing, scheduling, and the operational metrics PE investors use to evaluate portfolio returns. Responds to messaging that quantifies operational impact: cost per encounter reduction, staff productivity improvement, no-show rate reduction, billing efficiency gains.
The Director of Procurement or VP of Supply Chain. For product and supply categories including medical devices, consumables, equipment, and in some MSOs software, this role is the direct purchasing authority. Manages vendor relationships, negotiates contracts, and administers group purchasing agreements covering the entire practice portfolio. A professional buyer who understands negotiation dynamics, GPO pricing benchmarks, and multi-site contract structures. Reaching this contact requires demonstrating awareness of the MSO procurement context.
The CFO. Involved in all significant purchasing decisions through the lens of financial impact on the management fee model and the PE return profile. For purchases above the COO’s approval threshold, CFO sign-off is typically required. Responds exclusively to ROI framing that is specific and defensible. Not “our product saves money,” but “based on your per-encounter cost structure across your 30-practice portfolio, an implementation would produce an estimated X in annual savings.”
The parallel to how government procurement works is instructive for vendors who sell across sectors. As Civic Data documents in its guide to state and local government technology spending, government purchasing also separates the technical evaluator, the budget authority, and the final approver into distinct roles at different organizational levels. Vendors who have built role-aware contact strategies for the government market can apply that same discipline to MSO outreach with meaningful efficiency gains.
What MSO executives actually care about
The purchasing priorities of MSO executives are shaped by the PE return model underlying most MSO structures. PE investors in physician practice consolidation focus on EBITDA growth and multiple expansion. Every purchase an MSO executive approves should, in their calculus, either grow revenue or reduce cost in ways that improve the earnings picture PE investors use to value the investment.
Cost reduction is the most consistent driver. Procurement consolidation across practices, reduced per-encounter supply costs, elimination of redundant vendor relationships, and technology platform standardization are all decisions MSO executives can justify directly through the savings they produce.
Revenue optimization is the second driver. Scheduling efficiency that reduces no-shows. Billing optimization that improves clean claim rates. Patient retention platforms that grow the panel. Each category has a clear revenue impact narrative that MSO executives can evaluate in financial terms.
Operational standardization is the third driver. MSOs managing large practice portfolios want to standardize operations across sites to reduce management complexity and enable performance benchmarking. A platform serving all practices on a single instance with centralized reporting offers a consolidation benefit that resonates strongly with MSO operational leadership.
Compliance risk mitigation is the fourth driver. Healthcare regulatory exposure, billing compliance, and data security are areas where MSO executives have significant personal liability. Products reducing compliance risk have a defensible ROI even when operational savings are not immediately apparent.
Why MSO executives are missing from legacy contact databases
The challenge with reaching MSO executive buyers is that they are systematically absent from legacy physician contact databases. MSO organizations are relatively new entities created by the consolidation wave, and the executives running them did not come from physician practice backgrounds that would have placed them in traditional medical directories or NPI databases.
Building MSO executive contact data requires a different sourcing approach: monitoring healthcare industry news for PE acquisition announcements, tracking the formation and growth of specific MSO organizations, researching organizational structures through MSO websites and LinkedIn, and direct verification of executive contact information. This is a research-intensive process that most healthcare vendors have not invested in — which is precisely why MSO outreach remains an underexploited opportunity.
The same data gap problem affects vendors selling across multiple verticals. The community college VP of Workforce Development role that has grown fastest in purchasing authority is also underrepresented in legacy higher education databases, as College Data documents in its guide to selling into community colleges. In both cases, the opportunity is accessible to vendors who invest in current, role-specific contact data rather than relying on legacy directories built for a market structure that no longer exists.
The MSO outreach messaging framework
MSO executive outreach fails most consistently because it is written for physicians, not for professional managers. A message leading with clinical outcomes, patient care improvement, or physician satisfaction is addressing the wrong priorities for an executive whose evaluation framework is financial and operational.
The subject line should reference operational or financial context specific to the MSO’s scale. “For Multi-Site Practice Operations: Reducing Per-Encounter Supply Cost Across Your Portfolio” signals the email was written for someone managing multiple practices, not a single-office physician.
The opening line should establish financial or operational context demonstrating understanding of the MSO model. A reference to procurement consolidation opportunities at portfolio scale, standardization advantages across sites, or a specific financial metric relevant to the MSO’s category signals that the vendor understands the business.
The body should be brief, specific, and ROI-forward. One problem statement. One solution description. One concrete financial outcome from a comparable MSO. The ask should be a short financial conversation: “I would like 15 minutes to walk through how a similar MSO in your specialty reduced per-encounter supply costs by X. Would that be worth your time?”
Building MSO-aware healthcare contact infrastructure
- Segment your healthcare contact database into clinical physician contacts for preference-setting and MSO executive contacts for purchasing conversations. These are different outreach tracks requiring different messages, different timing, and different follow-up sequences.
- Identify the MSO organizations active in your highest-priority specialty categories and metropolitan markets. A handful of MSOs in a given market may control purchasing for a majority of the relevant practices.
- Map the executive hierarchy at priority MSO targets before sending any outreach. CEO for strategic conversations. COO for operational efficiency pitches. Procurement director for supply and product categories. CFO for ROI conversations above the COO’s approval threshold.
- Build ROI models specific to MSO economics. Per-encounter cost savings across a 20, 30, or 50-practice portfolio. Billing efficiency gains expressed in annualized collections improvement. No-show reduction expressed in revenue per appointment slot recovered.
- Update your MSO contact data quarterly. Consolidation activity continues to create new MSO organizations. Executive turnover at PE-backed companies is higher than at physician-owned practices. A contact database that is current six months ago may be significantly stale today.
The bottom line
The shift of healthcare purchasing authority from individual physicians to MSO executives is one of the most significant structural changes in the B2B healthcare market in the past decade. Most vendors have not fully adapted their contact strategy, their messaging, or their data infrastructure to this reality. The organizations that do will find a relatively uncontested outreach lane to buyers who control purchasing at a scale that individual physician relationships cannot match.
