Using a Parent Child Hierarchy in SQL Server to Implement a Custom Security Scheme

I have a requirement to implement a custom security scheme where roles and the user's place in the organization hierarchy are used to determine which customers a user can access. In particular the requirements are that a sales person can only access their customers and any other role can access any customer in their level of the organization hierarchy and below. We have a simple hierarchy that is made up of regions and offices. Can you provide us with an example of how to do this?
