Overview Overview Culture Results News


Sedgwick has come a long way from its modest beginnings as a two-attorney law firm to our current status as an international trial firm with 14 offices, dozens of practice areas and more than 250 attorneys worldwide. 

The firm that would become Sedgwick LLP was founded in 1933 in San Francisco and continued to grow through the 1930s and 1940s, expanding its service offerings and solidifying its reputation as a trial and litigation firm. The 1950s represented the emergence of the first multiplaintiff consumer litigation. Sedgwick was chosen to represent Cutter Laboratories in the polio vaccine lawsuits that filled the courtrooms during most of the 1950s. The firm name Sedgwick, Detert, Moran & Arnold was adopted in 1959 and shortened to Sedgwick LLP in 2011.

Firm Culture

More than 80 years ago, two attorneys formed what is now the international trial and business law firm known as Sedgwick. With 250 attorneys in 14 offices around the world, Sedgwick’s collective experience spans the globe and virtually every industry. Sedgwick’s growth and expansion has not altered the core values that have defined the firm since its formation. The legacy of its founders, unparalleled client service, integrity, creativity and the highest quality legal services, continues to define Sedgwick’s core values and culture today. While our core values define us, our strength is derived from our commitment to a progressive work environment that empowers and challenges our attorneys and professional staff to achieve excellence and to effect positive change in the legal and business communities we serve. At Sedgwick, we enjoy working in a diverse environment that values individual talents, abilities, personalities, cultures and backgrounds. Our firm’s leaders foster an atmosphere in which people of all backgrounds are given access to the mentorship, education and opportunity critical to reaching their full potential.

Our firm is committed to the communities in which our employees live and work. Through our pro bono initiatives we provide services to a variety of underserved groups. Sedgwick employees regularly team together to volunteer their time and energy for local charitable institutions and causes and can often be found working with the homeless, disadvantaged and children forgotten by the system.

A collegial atmosphere was embedded in Sedgwick’s foundation in 1933, and we know that our clients are better served by a firm whose members truly enjoy working together. We are proud of our firm and will hold true to those values that have driven our success, thanks to the ongoing efforts of all of the members of the Sedgwick family.



Defense verdicts. Dismissals. Summary judgment. Appellate rulings. Our clients come to us for what we do. How well we do it is defined by our clients' successes.
