Why use an advisor
- One conversation instead of five vendor sales processes.
- You buy directly from the provider you choose, at the same or better pricing: providers quote sharper when they know the whole market is being compared.
- Advice that includes "don't buy this," because we have no stake in which provider wins.
- Coverage of the whole market, including providers you've never heard of.
- Provider claims checked against what advisors see across live quotes, not against brochures.
