Selling a Medical or Aesthetic Practice in Seattle

Washington bans the corporate practice of medicine through case law rather than one express statute, and the doctrine is among the most restrictive in the country. A non-physician, a private equity firm, or a general corporation cannot own a medical practice or control clinical care in Seattle. The lawful path is the MSO and friendly-PC model: a physician-owned professional corporation keeps the clinical license and patient care, and a separate management services organization, the part a non-physician investor can own and fund, contracts under a management services agreement to handle non-clinical operations. Washington adds a local wrinkle that makes structuring uniquely complex: an MSO cannot lease property to or purchase hard assets from the private equity investor, two structures that are standard in most other states. For the full statutory treatment, including the 2SSB 5387 legislative effort, see our Washington state hub. This page focuses on how those rules play out in the Seattle deal market.

It tried, and the restrictive bill did not become law. In January 2026 the legislature introduced Second Substitute Senate Bill 5387 to codify and sharply tighten the corporate-practice ban, including banning unlicensed-entity ownership of healthcare practices and prohibiting dual-ownership and dual-employment MSO arrangements, with a proposed effective date of January 1, 2027. That bill failed to advance from the Senate in late March 2026, so the restrictive bill is not law. The implied common-law ban plus the MSO and friendly-PC model remains the operative reality. The recent push signals real intent to restrict private-equity-style structures, and a buyer will price that risk, which is one reason Seattle owners who are weighing a sale value a clean structure now rather than later.

No. There is no published Seattle-specific multiple, and we will not quote one. What we use is the national vertical range for your practice type, then we explain how Washington law and the Seattle market move structure and value. A practice that is already cleanly structured for compliance, with a defensible management agreement and a durable friendly-PC relationship, transacts faster and holds its value. A practice that is not invites re-trading and discounts. Verified buyer activity in the Seattle metro supports the national range for a well-prepared seller, but it does not create a citable city multiple. Your real number comes from a confidential, practice-specific analysis.

Washington is a smaller, Seattle-anchored aesthetic market. A data set published by Orbital, drawing on the American Med Spa Association 2024 State of the Medical Spa Industry report and US Census County Business Patterns, counts roughly 230 medical spas statewide, ranking Washington fourteenth nationally out of 10,488 med spas in the United States. Seattle is the state’s dominant metro and holds the largest share of that pool. There is no independently citable count of med spas for Seattle alone, because directory scrapes that report far higher metro figures count non-physician day spas, salons, and beauty clinics rather than true medical spas, so we frame density at the verified state level and rely on the qualitative reality that Seattle leads the Washington market. Treat the figures as data-set estimates, not a state-certified statistic.

Yes, unless and until you choose to tell people. We run every process under strict confidentiality, with confidentiality agreements, secure data rooms, staged disclosure, and a vetted buyer process. Premature disclosure can unsettle staff, shake patient confidence, and weaken your negotiating position in a competitive Seattle market, so you decide what is shared, with whom, and when. Because a Seattle deal runs through a management-company and friendly-PC structure, we plan that structure openly with you so confidentiality and compliance hold together through close.
