Who We Are / Overview

Clausen Miller has proudly represented the insurance industry since 1936. In us you will find a group of diverse and experienced attorneys who are business-minded, strategic counselors, as well as efficient, aggressive litigators. For over 80 years, we have valued hard work, efficiency, and integrity. We believe that partnering with our clients–understanding their business, their needs, and their goals–is the best way to secure resolution on their terms.


In June, 1936, Donald Clausen, Herbert Hirsh, Norman Miller, and three associates opened what is now known as Clausen Miller. This firm would establish itself as a skilled and thoughtful legal pioneer for the insurance industry. What started as a small office has since grown in size, scope, depth, and geography. We are now a national law firm, strategically located throughout the United States, with international capabilities and resources. We are also a founding member of Clausen Miller International, a cooperation of leading independent law firms with affiliates in London, Paris, Rome, and Brussels that practice in all aspects of insurance and reinsurance law.

Diversity & Inclusion

Clausen Miller is committed to the development of diverse attorneys through recruitment, mentoring, and promotion. We support the inclusion and advancement of exceptional attorneys with diverse backgrounds who are committed to providing the outstanding client service for which we are known. We believe that the collective strength of our attorneys lies in their legal abilities, as well as their cultural and life experiences.
