Who We Are

Four Decades of Local, Independent Insurance

Atchison Insurance Agency was founded in 1982 and has called the St. Charles area home ever since. From our office in the heart of Cottleville, we’ve spent over four decades helping our neighbors find the right coverage for their cars, homes, families, and businesses.

Because we’re independent, we’re not locked into one company’s products. We represent multiple top-rated carriers, which means we’re free to shop the market on your behalf and recommend the coverage that actually fits your life — not whatever one insurer happens to sell. When something changes or a claim comes up, you reach a real person who knows you and your policy.

We Work for You

As independent agents, we aren’t tied to any single insurer. We represent you — so our advice is built around your needs, not a sales quota.

We Shop the Market

We compare coverage from 9+ top-rated carriers to find you strong protection at a competitive price, and we re-shop as your needs change.

Local & Personal

Based in Cottleville, we know this community. You’ll always reach a real person who knows your name, your policy, and your history.
