Concentrating on Workers' Compensation Defense

About Us



We are a community of professionals who enjoy our work, our clients, and our associations with each other.

Founded in 1998, our office concentrates on defending California employers in workers' compensation and related labor law matters. Located in Century City, California, we provide legal services to major corporations and other clients headquartered throughout the United States. We are proud of having distinguished our firm by working with our clients to assist in implementing safety prevention measures, investigating industrial injury and discrimination claims, reviewing medical protocol, and reviewing Return to Work policies. We emphasize an integrated approach to resolving industrial injury claims by requesting that employers and insurance carriers actively participate in the defense of claims, in an effort to reduce overall costs.

Our practice provides detailed and thorough representation regarding all aspects of industrial injury claims, from investigation to Trial. Our representation covers claims of orthopedic and psychiatric injuries, chemical and toxic exposure, discrimination actions under Labor Code Section 132a, as well as allegations of Serious and Willful violations. A staple of our practice is to apply civil litigation skills in the workers' compensation arena. Thus our Attorneys are trained to have a comprehensive understanding of California labor, litigation and other laws and regulations applicable to our business. We are solely dedicated to representing the employer side of workers' compensation matters. We actively track legislation pending before the California State Assembly and before the federal government. We issue periodic legislative updates to our clients, and our Attorneys are available to present seminars on workers' compensation and legislative issues.
