The short version. A non-physician owner of an established aesthetics practice wanted to add hormone therapy,
IV therapy and medical weight loss. California is the strictest corporate-practice state in the
country, so the owner could not simply hire a physician and start prescribing. About seven
months passed between the first conversation and the first patient under the new lines, and
almost none of that was clinical work.
What this is. A real MDside engagement, described without naming the client. No client name, location, ownership or commercial terms appear here, and nothing below identifies the practice. It is not a client case study and it is not a testimonial: the client has not endorsed us and is not quoted. The regulatory points are cited at the foot of the page.
What the practice already had
An owner-operated aesthetics business, already running injectables under a delegation arrangement, with an established patient base and a physical location. The owner is not a licensed physician. The ambition was three additional service lines — testosterone replacement, IV therapy and medical weight management — each of which is a materially bigger regulatory step than neurotoxin injection.
The three lines fail differently. Hormone therapy means a controlled substance and an ongoing prescribing relationship. Weight management means GLP-1 sourcing decisions and the compounding rules that came with them. IV therapy means an ordering provider standing behind every bag. None of the three is satisfied by the arrangement that already covered Botox.
Why California made this harder than it would have been elsewhere
In California a non-physician cannot own the entity that practises medicine. That is not a paperwork preference, it is the corporate practice of medicine doctrine, and California enforces it more actively than any other state. The medical side has to sit in a physician-owned professional corporation, and the business the owner already had relates to it through a management services agreement rather than owning it.
The timing mattered too. SB 351 took effect on 1 January 2026, barring management companies and their investors from controlling clinical decisions and giving the Attorney General enforcement authority. Any management agreement written before that date had to be read against it — specifically the provisions that let a non-clinical party sign off on staffing, protocols, or what gets offered to a patient.
The practical consequence for this owner: the structure had to be built to a standard that was still changing while it was being built.
What MDside actually supplied
- A named medical director — a physician licensed in the state, who is a real clinical authority over the medical services, not a signature on a wall.
- A second covering physician, so the practice was never one holiday or one illness away from having no medical oversight.
- A third physician for jurisdictional gaps, because the owner’s growth plan crossed state lines and licensure does not travel.
- Protocols and delegation documentation for each new line, written to what the state actually requires rather than adapted from a template for another state.
- Operational plumbing: a reference lab account for hormone panels and a pharmaceutical distributor account for injectables, so the clinical programme could actually run rather than existing only on paper.
What MDside did not supply is as important: we are not the owner’s lawyer and we did not form the entity. Structure of that kind belongs with healthcare counsel licensed in the state, and this engagement proceeded alongside one.
Where the seven months went
Almost none of it was clinical. Physician licensure and credentialing runs on the boards’ timelines, not yours. Agreements had to be drafted, reviewed by counsel and signed. The lab and distributor accounts each have their own onboarding, and both want to see the medical entity before they will open. The protocols had to be written per line and per state.
This is the honest answer to the question every operator asks first, which is how fast this can be done. A vendor promising a fortnight is quoting the time it takes to sign a contract, not the time it takes to be able to defend the arrangement to a board.
What we would tell the next owner in this position
- Decide the service lines before the structure, because the lines determine what the structure has to support.
- Assume licensure is the critical path and start it first.
- Read any management agreement drafted before 2026 against SB 351 before relying on it.
- Do not let the fee arrangement drift toward a percentage of medical revenue; that is the part regulators look at hardest.

Frequently asked questions
Can I just hire a physician and skip the professional corporation?
Not in California. The entity that practises medicine has to be owned by a licensed physician. Employing a doctor inside a business you own does not satisfy the doctrine — it is closer to the arrangement that gets cited in enforcement actions.
How long does this take, honestly?
This engagement ran about seven months from first conversation to first patient under the new lines. Faster is possible where licensure already exists in the state and the service lines are simpler; much faster than that usually means something was skipped.
Does adding hormone therapy change the medical director requirement?
It changes what the director has to actually do. A controlled substance and an ongoing prescribing relationship carry oversight obligations that a single aesthetic procedure does not, and the protocols have to reflect that.
Why will you not name the client?
Because they have not agreed to be named. When we publish a client case study it will say so on its face and the client will have approved it in writing. Everything on this page is written so that no practice is identifiable.
