Criminal Defense & Professional License Defense Representation in Orange County
As a highly qualified and experienced Laguna Beach criminal defense attorney who has advocated on behalf of individuals throughout the Orange County area for more than 25 years, I know what is at stake in cases involving serious criminal allegations or accusations of dishonesty, malpractice, or fraud. I have aggressively represented clients facing DUI charges, sex crime accusations, and drug charges. Your livelihood, your future, and your freedom may be hanging in the balance, but I am wholly devoted to helping you secure the results you need to move forward with your life.
Whether you have been arrested, a loved one has been accused of a crime, you are being investigated by a licensing board, or you are facing allegations by a licensing board, I can help protect your rights. By choosing my firm, you will be represented by me directly, which means you will have individual, one-on-one access to a skilled professional who is personally invested in the success of your case.
Proudly Serving the Orange County for Over 25 Years
Unlike most firms, I do not keep my clients at a distance or in the dark. I make every effort to keep you informed of your rights and any case developments. You are unique and so are the facts involved in your case, and you deserve legal advocacy that recognizes your side of the story. We have years of criminal defense experience in Laguna Beach, Laguna Hills, and Orange County.

Saved my RN License
Alan is my saving grace! I received a dreaded letter from the board of nursing that my license was being investigated. The worst letter anyone who has a license can receive. I was so scared and I knew that my livelihood was literally on the line. I contacted Alan who I found online. When I sent a me...

Previous Client
I was facing a serious, violent criminal felony that carried a lengthy prison sentence. I knew I was innocent of all charges so I went on the hunt for a criminal defense attorney. I interviewed a myriad of attorneys. Every single one of them sounded pessimistic about my case. One attorney even sta...
Alan Castillo's Lawyer Endorsements
"I have known Alan for over 25 years. We worked as colleagues in the Orange County Public Defender’s Office, later I consulted with him on cases in private criminal defense practice. I am pleased to endorse Alan, who is one of the most knowledgeable and experienced attorneys I know in the field of DUI defense. His depth of understanding in this complex area is unmatched, and he is consistently a reliable resource for fellow attorneys seeking guidance or insight. Beyond his impressive expertise, Alan has built a strong and well-deserved reputation in the legal community for his professionalism, integrity, and dedication to his clients. His combination of skill, experience, and generosity in sharing his knowledge makes him an invaluable asset to both his clients and colleagues."
"I recommend Alan Castillo unequivocally. He is a strong litigator and conscientious protector of his client’s rights. His knowledge in particular to the ins and outs of DUI law is especially incredible. You would be well-served with his legal services."
"I endorse this lawyer. Knows DUI's better than anyone I know. Great person and even better lawyer."
"I endorse this lawyer. Alan Castillo is one of the most talented criminal defense attorneys that I know. Not only is Mr. Castillo one of the most talented criminal defense attorneys that I know; but he is also one of the most talented DUI Defense Attorneys that I know. He is a skilled negotiator and a highly skilled trial lawyer. I highly recommend this lawyer to anyone seeking a criminal defense attorney or issues with any professional licenses he/she may have."
"I have known Al Castillo for over 15 years since we both worked in the Orange County Public Defender's Office. Al is an extremely knowledgeable attorney in the filed of DUI law and criminal law in general."
"I have known Alan for about 15 years. During that time I have seen first hand his dedication to each and every client. He leaves no stone unturned and the result is that he consistently gets great results for client. In a recent case with facts I was familiar with, I saw him get a truly extraordinary result which saved the client from a felony and jail. Given the facts, I am still not sure how he did it. I would enthusiastically recommend this attorney."
"Mr. Castillo has shown as a member of the National College for DUI Defense that he is committed to providing cutting edge DUI defense. The National DUI College members represent the most experienced DUI defense attorneys in the country. If you are charged with a DUI, a general practice lawyer is not the answer. Good DUI defense is hard work and few offenses in our court system call for greater attorney expertise than cases involving driving under the influence of drugs and alcohol. DUI cases are especially complex because they require defense counsel to understand BOTH scientific and legal issues. As a fellow member of the College, if you are looking for exceptional representation, I would not hesitate to recommend Alan Castillo."
"It is with pleasure that I recommend and endorse Mr. Castillo to anyone who wants a superb and caring attorney. I have had the opportunity to send clients to Mr. Castillo for help with unpleasant matters in Laguna Beach. These were not only clients, but some were friends. The best endorsement that I can give to any other lawyer is to refer my clients to them for assistance."
"Alan is one of the great trial lawyers! He's a true champion of his clients. He has earned the respect of both Judges and Prosecutors in every courtroom he enters."
