- [Step 1: Pick your state and entity types](https://dso.getlemma.com/start/zero-to-paid/pick-your-state-and-entity.md): Choose your launch state by reading its dental practice act: proprietor clauses, DSO registration regimes, the genuinely permissive states, fee-structure bans, and where to organize the DSO.
- [Step 2: Find your friendly dentist](https://dso.getlemma.com/start/zero-to-paid/find-your-friendly-dentist.md): What the dentist-owner of your professional entity actually does, why genuine clinical authority decides enforcement outcomes, how they're paid, and how succession windows work.
