Helping an out of state student

Attorney Deniz was responsive, professional, and knowledgable. I didn't understand why I was arrested over not signing for a parking citation while on a delivery job, but it turned into something that needed to be handled, and I was leaving the state in a few weeks after graduating school. Due to his... efforts no further legal action was taken. Thank you Attorney Deniz, C.M.

Connected, aggressive, compassionate, and results outcome-focused

Hiring Mark Deniz was the best decision I made after my DUI arrest. If you’re looking for the best DUI lawyer in San Diego or an experienced California DUI attorney, he is the one you want in your corner. From the start, he showed real compassion; even speaking with my wife the night of the incident ...to reassure her. He is highly knowledgeable, well-connected, and has the perfect balance of being strategic and aggressive in handling a case. In my situation, CHP stacked multiple charges, but he was able to have them reduced and negotiated a much lighter sentence than I thought possible. He also provided a clear roadmap for both the court and DMV processes, which took away so much of the stress and confusion. His communication is very direct, and while he gives a lot of information at once (sometimes I had to ask him to repeat or clarify), he was always responsive and usually got back to me within a day. Another thing that stood out is that unlike many firms where you’re passed off to associates, he personally handled all of my court appearances and representation himself. His staff helps with administrative work, but he’s the one standing by you in court. His fees were also affordable compared to other attorneys I spoke with, and worth every penny. Overall, I felt supported by someone who genuinely cared about my outcome and had the skill, connections, and determination to achieve the best result possible. I strongly recommend him to anyone searching for a top-rated DUI lawyer in California.

Best DUI Lawyer in SD

Mark is an amazing lawyer. He picked up my case last minute and helped me through the whole process. This was all new to me because it was my first time getting arrested. He is professional and easy to contact . With his help my case was dismissed and doesn’t even show up on my record. In my opinion ...mark was affordable and offered different payment option which was awesome. I would definitely hire mark again.

 Thank you for the kind words.  Communication is key for us.  I know people have a cloud over their head when they are going through the case.  I work hard to keep the trust people give me.  I was glad to have been a help. It is easy advocating for a nice person. The future is nothing but up for you.

Outstanding Defense Attorney

I highly recommend Mark Deniz as a defense attorney. Having never been arrested for anything in my life I did not know where to turn upon a dui arrest. My wife suggested I get an attorney, so I started by looking on the internet. I was immediately drawn to Mark’s background as a prosecutor and as a d...efense attorney. It was Father’s Day and really didn’t expect to reach Mark. I left a message and heard back from Mark in five minutes. After that initial phone conversation I knew I had made the right decision. Mark took over immediately, handling all aspects of my case. I literally did not have to do anything. To make a long story short Mark was able to get my charge reduced below a dui with only a small fine. Mark’s fees were extremely reasonable as was his payment plan. Again Mark I thank you and your team for being so understanding and so strong for me through the entire process. If you need a strong defense attorney who really cares, no need to shop. Just call Mark Deniz.

You are a benefit to the community.  You were easy to come in an advocate for.  When I was a prosecutor I knew good people were coming into the process seeking fairness. The punishment did not always fit the act. It takes hard work, communication with the prosecution/judge, as well as having sound legal arguments. I am glad to have the pleasure of advocating on your behalf.

Expert defense for DUI

I’ll start off by saying I have a few friends who are defense attorneys in different states so had some sound advice as to what I should look for. Their biggest advice was you don’t want a lawyer that tries to use fear tactics to get you to book retainer, and when you tell your case you want someone ...who has full confidence and doesn’t bat an eye. Mark checked both of these boxes with ease. I was facing a felony dui with injury in the Vista courthouse which is incredibly harsh, so I did my due diligence and called around. I spoke with probably 12 lawyers and ultimately decided with Mark. From initial consultation, to answering all of my additional questions, Mark was very transparent and had clear plan of attack. I am not a person who drinks and drives and received my charge in a very dumb way when I had a lapse in judgment and drove a golf cart and my friend fell off. My case was riddled with police errors which made everything incredibly frustrating, however the law really feels like it is guilty until proven innocent and I was determined to take it all the way til the end. That being said, Mark has great relationships with the DA office and was able to negotiate down to a plea I was more than happy to sign and glad to start putting everything behind me. DUI are scary, frustrating, and have a substantial impact for many careers. If you are in the unfortunate situation do yourself a favor and give Mark a call. So many big name firms pass your case off to paralegals or won’t call back. Mark is the person you pay for and he is the one who is there standing by your side.

A big part of being a good advocate is the ability to get a client's story.  I was able to hear a story that provided context for what was happening.  This big-picture approach is one way to show the issues in the case, while highlighting your character. Glad we nipped it in the bud promptly. I narrow my practice to work with quality people as much as I can.  This case is an example of working with someone you want to go fight for.  Thank you for the kind words.
