What distinguishes your law firm from others?

O’Brien & Associates believes its first responsibility is to serve its clients. This means more than providing excellent legal services. This means providing excellent customer service as well. Our case reporting standards are second to none. Our attorneys are available whenever you need them. Our response time is unparalleled.
