Relational DB for attorneys/location/practice area

For a proposed attorney website to replace an existing site we did in php. We are new to WordPress. On the current php site, we use a MySql DB to create an attorney roster with profiles. User can view list of practice areas, click on one, and then view list of attorneys that fit that practice area. Can view list of office locations, click on location and view all attorneys at that location. Can view list of attorneys and view complete profiles/bios. All related, entered once in the backend. Want to port the site to wordpress and then use a plugin if available to manage and maintain the roster with these same relationships and search capabilities. Anyone know of a plugin that fits the bill out of the box or with a little customization?
