Firm Information

Overview

Rose, Klein & Marias LLP proudly serves clients in Ventura, California, who are dealing with injuries, unsafe working conditions and a wide range of employment-related disputes. Our practice is focused on protecting individuals harmed due to negligence or workplace misconduct. We work hard to hold those responsible parties accountable while pursuing the financial recovery and legal remedies our clients deserve under the law.

Our experienced attorneys focus on workers’ compensation, personal injury and motor vehicle accidents, as well as claims involving dangerous or defective products. Our attorneys also handle employment law and discrimination cases and represent clients suffering from asbestos-related diseases, including mesothelioma. This experience allows us to address both immediate legal concerns and long-term impacts.

We prioritize careful case preparation and open communication. From the first consultation, we work to understand how a legal issue affects a client’s health, career and family. We provide clear explanations and realistic assessments so clients can make informed decisions.

Founded in 1936 by Victor C. Rose in Los Angeles, our firm grew with the addition of Alfred M. Klein and later, Eugene Marias in 1946. Their shared dedication to protecting the rights of injured workers and individuals created a lasting legacy of service throughout California.

We are prepared to advocate forcefully for our clients through negotiation, administrative proceedings or litigation when necessary. Throughout the process, we focus on communication, keeping clients informed and involved as their case moves forward.

Whether resolving a case through negotiation or pursuing litigation, we are prepared to advocate firmly. At Rose, Klein & Marias LLP, we remain dedicated to serving the Ventura community with integrity, experience and a commitment to achieving meaningful results for our clients.
