Simon Wilson

CEO, Markel Insurance

Markel’s insurance leadership team is committed to serve our customers, create great outcomes for our employees, and build the value of the organization. To us, insurance isn’t just a policy – it’s a vital promise that gives people and businesses the confidence to move forward, each and every day.

At Markel, we believe you’ll find exceptional people, without the ego – people who bring out each other’s best, and support each other at every turn, because it’s who we are, and the secret to our success.

The Markel Style provides us an atmosphere that allows us to focus on doing what’s right and on serving others. We bring together broad-ranging expertise, innovative thinking and expert claims handling to deliver even better solutions.

We are there for our insureds on their worst day, and our job is to make everyone who comes in contact with us better for having done so.
