Client Service Team

Our team is in the client service business. If a team member isn't working directly with you, they are supporting the people who are. Our team is interdependent, each having specific skills and experience that allow us to provide exceptional service.

We are dedicated to the well-being of our team. North Berkeley provides comprehensive benefits that include: 100% of health insurance premiums for team members and everyone in their immediate family, bonuses, pre-tax profit-sharing, paid time off to do volunteer work in the community, and free comprehensive service as clients of the firm, so we all know what it is like to be clients of the firm.
