Business Entity Formation & Corporate Governance3 min readUpdated September 2026

The MSO Structure Behind a Multi-Site MedSpa Entity

A medspa offering injectables, laser treatments, or other medical procedures is a medical practice first and a spa second, which means it usually runs into the same corporate practice of medicine restrictions a doctor's office does: a licensed physician, not an outside investor, generally has to own the clinical entity.

That single constraint shapes the entity decision more than anything about the medspa business itself, so it's worth working through before comparing Bizee and Doola. A lot of medspa operators only discover the restriction after they've already lined up outside capital, which is the wrong order to find out; get the structure question answered before you're negotiating an investment on the assumption of direct ownership.

The PC-and-MSO Split, Applied to a MedSpa

Similar to a dental support organization, a multi-site medspa typically splits into a professional corporation owned by a licensed physician that holds the clinical practice, and a management services organization, which can have outside investors, that provides the business side under a management services agreement. The physician-owned PC employs or contracts the medical staff and retains authority over clinical protocols; the MSO handles marketing, scheduling, facilities, and other non-clinical functions.

Formation vendors like Bizee and Doola file the entities once this structure is designed; they don't design it, and getting the split wrong, particularly letting the MSO exert too much influence over clinical decisions, is a legal risk that goes well beyond a filing error.

A multi-site medspa structure usually rests on these pieces:

  • A professional corporation owned by a licensed physician that holds the clinical practice and retains authority over clinical protocols.
  • A management services organization, which can take outside investors, that handles marketing, scheduling, facilities and other non-clinical functions.
  • A business associate agreement between the PC and MSO covering patient information, in addition to each entity's own HIPAA compliance program.
  • A documented medical director for each location, plus facility licensing confirmed well before opening.

Who Can Actually Perform the Procedures

State medical boards set specific rules for which procedures a physician must perform personally versus which can be delegated to a nurse practitioner, physician assistant, or registered nurse under supervision or a standing protocol, and those supervision requirements vary meaningfully from state to state. This isn't an entity question exactly, but it directly affects your staffing model and your management services agreement, since the MSO needs to know which roles it's actually recruiting and scheduling for.

Confirm your state's specific delegation and supervision rules with a healthcare attorney before you build your service menu and staffing plan around procedures your license structure may not actually support the way you assumed.

Facility Licensing Is Separate From Entity Formation

Beyond the entity filing itself, many states require a separate facility or business license for a medical or aesthetic practice location, sometimes tied to specific equipment like lasers. Confirm your local and state facility licensing requirements for each new location well before opening, since this timeline often runs independently of your entity formation and can be the longer pole in the tent for a new site.

HIPAA and the Management Agreement

Because the MSO handles scheduling, billing, and marketing that touch patient information, the PC and MSO typically need a business associate agreement between them in addition to each entity's own HIPAA compliance program. This is a common gap in growing medspa groups: the two entities exist and operate correctly day to day, but nobody formalized the data-sharing agreement HIPAA expects to sit underneath that relationship.

A Medical Director at Every Location

Many states require a location performing medical aesthetic procedures to have a designated medical director, a licensed physician responsible for the clinical protocols followed at that specific site, even when that physician isn't there full time. As you add locations, confirm each one has its own properly documented medical director relationship rather than assuming one physician's oversight of your first location automatically extends to a new one across town.

The medical director relationship is usually formalized through the same PC that employs your treating clinicians, so keep this documentation organized alongside your clinical staffing records, not filed separately as an afterthought.

Device Purchases and Marketing Claims

Lasers and several other aesthetic devices are FDA-regulated medical equipment, and manufacturers typically require documented, device-specific operator training before staff can use them, tied to whichever entity purchased and registered the device. Keep a simple record of which staff are trained on which device at which location, since this is exactly the kind of documentation a state inspector or a malpractice claim will ask for.

On the marketing side, the FTC expects any objective claim about results, from a website testimonial to a social post, to be substantiated, and a medical practice carries extra scrutiny here on top of general advertising rules. Review your marketing content against what you can actually back up before an ad runs, not after a regulator or a competitor flags it, and have whoever manages social content for each location work from the same substantiation standard.

Executive Capability Standard

What Good Looks Like

A well-run medspa group has a physician-owned PC holding every clinical location, an MSO handling the business side under a proper management agreement, and staffing at each location that matches what the state's supervision and delegation rules actually allow.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Have a healthcare attorney confirm your state's corporate practice of medicine and supervision rules before designing the PC-and-MSO structure.
2. Do Manually:Audit each location's facility license and confirm it's current and matched to the procedures actually offered there.
3. Delegate:Assign someone to own the HIPAA business associate agreement between the PC and MSO as the group adds locations.
4. Automate:Use Bizee or Doola's compliance tracking for the mechanical entity filings once you're managing a PC and an MSO across several sites.
5. Buy:Bring in a healthcare attorney to design or review the structure before your first new location, not after you've already signed a lease.

Frequently Asked Questions

Can a non-physician own a medspa outright?

In most states, no, if the medspa performs procedures that require a medical license; the clinical practice generally has to be owned by a licensed physician, with non-physician investors participating through a separate management company instead. Confirm your specific state's corporate practice of medicine rules with a healthcare attorney before assuming either structure works.

Can a nurse or aesthetician perform injectables without a physician present?

It depends entirely on your state's supervision and delegation rules, which range from requiring the physician on-site to allowing supervision under a standing protocol without direct presence. Get this confirmed for your specific state and procedure type before building a staffing model around an assumption that might not hold.

Does each medspa location need its own facility license?

Often yes, separate from your entity formation, and sometimes tied to specific equipment like lasers or the type of procedures offered at that location. Check your state and local requirements early in the process for each new site, since this can take longer than the entity filing itself.
