At Mastagni Holstedt, A Professional Corporation, our attorneys have been zealously advocating for our clients for 40 years. Our large team of 46 lawyers, investigators, negotiators and consultants believes it is important to vigorously pursue your matter until the appropriate result has been reached. With offices in Sacramento, Stockton, Ontario and Pleasanton, California, our firm's practice is focused on a variety of personal injury, employment and labor, and workers' compensation matters. In addition, our firm is proud to provide legal representation to all of the state's police and firefighter unions.

The founder and lead attorney of our firm, David P. Mastagni, has tried in excess of 300 cases to verdict, including 100 jury trials in both state and federal courts. In 2003, he led a team of attorneys in receiving the largest law enforcement binding arbitration award in the state's history, and Mr. Mastagni has been selected to Super Lawyers along with six of our firm's other attorneys. Our firm has received an AV Preeminent* peer review rating through Martindale-Hubbell, a designation reserved for those firms demonstrating the highest level of legal ability and ethics.

As a firm, we strongly believe that the protection of rights is our ultimate commitment to our clients throughout the state of California. Collectively, we aggressively litigate on behalf of our clients in order to garner the best results. Our attorneys come from many diverse backgrounds, including civil rights, military, government and police work.

With offices located in several cities in the state, we are easy to locate. For clients who have personal injury matters, many of our attorneys speak Spanish or Russian in addition to English. We also offer free consultations to allow you to make an informed decision regarding the handling of your case.

*AV Preeminent and BV Distinguished are certification marks of Reed Elsevier Properties Inc., used in accordance with the Martindale-Hubbell certification procedures, standards and policies. Martindale-Hubbell is the facilitator of a peer review rating process. Ratings reflect the confidential opinions of members of the bar and the judiciary.
