Sieber Plastic Surgery Marin
What I’ve seen about Sieber Plastic Surgery Marin.
This spa is on the register, and it has not cleared my public-record screen. That is not an accusation about their medicine — the screen looks at their website, at whether their published details agree with their Google listing, and at their advertising copy. It means one of those did not hold up when I last looked. Ask them the questions on the check page before you book.
What to ask before you book.
- 01
Who’s the medical director?
California requires every med spa to have a licensed MD or DO supervising. If the front desk can’t name them, that’s your answer.
- 02
Who is actually injecting me?
RN, NP, PA, or MD — get the credentials in writing. Estheticians cannot legally inject. Ask before you sit in the chair.
- 03
What product brand and concentration?
Real Botox / Dysport / Juvederm with a lot number. If it’s vague ("a similar neurotoxin"), walk out.
None of these three is part of my screen — I have no way to see a licence from the public record. All three are on you to ask, and if they fumble any of them, that’s your sign.

I checked the state's licence file, the federal provider registry, the Medical Board's public record, this spa's own website and Google's listing — the lines above say which came back with a record, which came back empty and which I have not read — and I do not rate this spa or recommend it.
