Understanding the many complexities of employment law is a challenging matter. That is why Mr. Dieguez has dedicated his entire legal career to knowing and practicing employment law. As an experienced employment lawyer, Mr. Dieguez has a passion for employment law and vigorously representing his clients. He stands up for the ethical practice of the law and focuses on obtaining the best results possible for every client's case.  Mr. Dieguez has successfully tried both jury and bench cases in both State and Federal courts, as well as in front of the California Labor Commissioner.

Attorney Dieguez understands the stresses and emotional toll of litigation, and tries to resolve every case in the shortest amount of time possible under the circumstnaces.   However, Attorney Dieguez understands that not all cases can be resolved at an early stage, and therefore is not afraid to vigorously litigated cases and take them to trial or arbitration.  Clients of Attorney Dieguez benefit from high quality legal representation and a knowledgeable counsel with a winning track record. In addition, Attorney Dieguez makes it a point to be accessible to clients at all times. This ensures that you are fully informed on the progress of your case from start to finish.

In his spare time, Attorney Dieguez also enjoys boating, soccer, and most of all, spending time with his wife and son. To learn how you can benefit from the help of Attorney Dieguez and the entire team at Diefer Law Group, please call today and schedule a consultation!
