Build a messaging framework

I work in marketing at a private health clinic. Help me build a simple messaging framework for the firm.

Context: Clinicians and front-of-house staff describe the clinic differently, and each promises a little more than the last. One agreed page stops the website and the phone script drifting apart.

Before you start, ask me for anything missing from this list:
- Who we help
- What we do and how it differs
- Proof for each claim

Then:
1. Write one sentence that says who we help and how.
2. Add three supporting messages with proof.
3. List phrases to use and to avoid.

Give me:
- A one-page framework
- A 25-word and a 50-word description of the firm

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general health information only. Never write anything that reads as advice on a person's own condition, and never suggest a treatment is certain to work or free of risk.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else our clinical lead or the registered manager who approves marketing should see:
- Evidence behind each claim about results or safety
- Use of specialist, expert, leading and painless
- The clinical lead's agreement before it is used
