FORMER SAN DIEGO PROSECUTOR. TOP RATED BY CLIENTS AND PEERS.
Former Veteran Prosecutor dedicated to Criminal Defense who works tirelessly with efficiency.

 Deniz is a native of Southern California.  He earned a scholarship playing college football. He earned the honor of Academic All-American.

 

After college he spent a few years as a high school educator and a varsity football coach.  He then followed his dreams and attended law school.  During law school he focused on helping people navigate through the legal system. He had internships with Prisoner Legal Services, Marin County Counsel, and Contra Costa Senior Legal Services. 

 

In January 2004, he joined the ranks of the District Attorney’s Office.  There, he learned behind-the-scene intricacies of criminal prosecution and was quickly promoted to Deputy District Attorney IV. Mr. Deniz worked closely with law enforcement. He went on ride-a-longs with police offices, reviewed police reports, filed criminal charges, negotiated plea bargain deals, interviewed expert witnesses and successfully tried more than 50 jury cases. He received training in evidence, trial technique, and felony sentencing from the California District Attorney Association.

 

In March 2009, he became a Deputy at the San Diego City Attorney’s Office.  As a Deputy City Attorney he spent time in several units including the Domestic Violence, Issuing, and general trial unit.  In 2012, he tried 13 jury trials alone.  He was Prosecutor of the Month for September 2011 and November 2012. He has conducted over 70 jury trials as well as hundreds of motions and hearings.  He handled thousands of cases while with the City Attorney’s office alone.

 

Mr. Deniz learned the prosecution's side of the law from the inside out, with all its strengths and weaknesses.  This is unique and vital knowledge for a defense attorney. Preferring private practice and being well-armed with first-hand experience in the District Attorney's office and the City Attorney’s office, Mr. Deniz opened his own practice, focusing on San Diego DUI and San Diego criminal cases.  With his depth of experience, he knew there were better ways to get favorable results besides the generic, impersonal approach often found in big law firms, and those without the knowledge of the inner workings of the prosecution.

 

Mr. Deniz opened his own law firm to satisfy clients' needs for individualized, professional services, tailored to give a quality defense that has reasonable and realistic fees.

At the Law Offices of Mark Deniz, Mr. Deniz provides his personalized, aggressive litigation expertise to each and every case. Your case will not be assigned to a junior-level associate. By handling the cases himself, Mr. Deniz provides his clients with top-shelf attention.  Criminal Law has many attended and unintended consequences; you must have quality representation. You have to try your best to get out of an unsympathetic and complex system.

Mark Deniz is active and up-to-date within the legal community.  This includes:

 

·               Attended the prestigious National Advocacy Center in Columbia, South Carolina.

·               Member of California DUI Lawyers Association

·               Member of National College of DUI Defense

·               Member of San Diego Criminal Defense Bar

·               Member San Diego County Bar Association

 

Mr. Deniz also sits on several consulting and referral panels throughout San Diego County.

 

Some other tidbits about Mr. Deniz include:

 

·               Former Special Prosecutor for the Auto Theft task force

·               Was Prosecutor of the Month in San Diego for September 2011 and November 2012.

·               Former member of the California District Attorney’s Association

·               Respected by judges, court staff, prosecutors, and his colleagues in the criminal defense bar.

·               Mark graduated from the prestigious and rigorous National College of DUI Defense Summer Session, held at Harvard Law School in Cambridge, Massachusetts.

*             Graduated from La Pier’s rigorous DWI Detection and Standardized Field Sobriety Testing course; he is certified in Standardized Field Sobriety Tests under NHTSA (National Highway Traffic Safety Administration).

Lakeside Ca Very Satisfied client !
After just getting my DUI, I decided to be wise and get legal representation. Right off the bat, after deciding to call Mark Deniz, quite quickly into our conversation, I noticed that he was a good listener. As i explained to him why i was contacting him, i could tell that we was quick to listen and did not make me feel like he was busy and never rushed me off the phone. Right away, I felt like I was speaking to an old friend and that meant a lot for me specially just having gone thru being pulled over for DUI. As the process unfolded, he was always very quick to respond to my emails or calls and always kept me in the loop of the process. His diligent responses gave me more than enough confidence in his skills and in him. This helped me to not worry about my case being forgotten. I feel very fortunate to have picked him as I have never done anything like this in the past. He definitely took care of everything. Money well spent. Even weeks after I need help filing some items to the court, he replied within the same day and took care of filing some paperwork and clearing a warrant for me. I never had to leave my home to close any gaps; he took care of all of it. He is very straight forward and will represent you at a phenomenal level. I live in Lakeside, Ca. and so happy to have called him. Thank you Mark !!

Response from Mark Deniz February 17, 2024
First off, thank you for the kind words. My staff and I are dedicated to getting the best outcome for our clients, whatever their specific situation is. A big part of this is the client being proactive, communicative, and part of the team. You were exactly that. That is why when the warrant was issued, I knew it was a clerical situation and nothing you did. I wanted to squash that bug asap to keep you on the path. I look forward to getting this more and more in your rear view mirror.

Excellent!
I was referred to Mark Deniz by a friend. Mark is very empathetic. He is a great communicator. Will respond to emails or text messages same day. He helped me reduce my charges to a wet reckless.
Response from Mark Deniz January 24, 2024
 What a great client.  You were easy to work with and advocate for. I always want to ensure you know what is going on every step along the way.   The process itself can be punishment and can be traumatic.  I want the process to be as easy as possible.

Case Resolved -Dismissal in 1 year
Just want to thank Mark for working with my son. He was facing a felony assault charge and Mark negotiated a plea deal that got this down to a misdemeanor. It will be dismissed in one year after completion of some classes and Cognitive Behavioral Therapy. Mark was kind, patient and compassionate . We felt seen and heard which was important to our family. I felt it essential that he knew us and he took the time to do this! You will not be disappointed with this lawyer.

Great Lawyer
Mr Deniz helped me get an early probation termination and expungement of my record. He was professional and straight to the point in assisting with getting my motion filed. I filled out a questionnaire and he did the rest. At the Court the motion was granted and my case was dismissed. I highly recommend get Mr Deniz for legal assistance as a lawyer. He is a great, awesome and processional lawyer.

Outstanding legal service
Grateful for the great service provided by Mark and the entire team. Communicated with me every step of the way and made sure I was notified and prepared for upcoming matters. Mark and the team provided a good payment plan that I could afford but never cut corners on their efforts in court. I am beyond grateful for a job well done. It was a long process but your efforts made sure I didn't experience any time behind bars. I would recommend this office for all your legal matters. Don't hesitate to give them a call immediately.

Response from Mark Deniz October 12, 2023
It has been truly an honor to come in and battle with you. As a lawyer, you need to see what needs to be done to get the best possible outcome. While you look at those tasks, you can see where corners can be cut. You have to have the fortitude to roll up the sleeves and do what is needed to get the job done. Part of how I get motivated is knowing I have a good person who is counting on me. Your case is a perfect example. We hit it at all angles before getting on the path. Bottom line, that path is going to be a dismissal. In the end, this could not be done without you. You have remained proactive and postive. Thank you for yo your efforts.

Mark and his team are the best!!
Back in June I got pulled over for a DUI and I was double the legal limit. This was my first offense and I had no idea what to expect. I called Mark and told him about my situation and how I was double the legal limit BAC. He talked to me for 30 minutes on the phone giving me some instant relief as I had no idea what to expect. I talked to a handful of lawyers but Mark made me feel the most relief and safe so I decided to have him represent me. My case ended a couple of weeks ago and I am so happy I went with Mark and his team. Mark always made sure I was being proactive and kept me updated with everything that was happening with my case. Having such a high BAC can get you in a lot of trouble but with Mark's hard work and determination he got me the best results that I could have possibly have. I wish I could give mark and his team more than 5 stars!!

3 DUIs defended
Mark was instrumental in helping me have my DL back to drive. I was about to lose my license because I had 3 DUIs, one of which was for legal/prescription drugs in my blood. I highly recommend Mark. He truly cares about you and your case and will make sure you have the best outcome.
Response from Mark Deniz October 20, 2023
Thank you for your kind words. 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 gave context to what was going on. This big picture approach is one way you can show the intent of a person (or lack thereof).

High Caliber Attorney Mark Deniz
I was facing a DUI charge. The experience of being arrested and facing this alone was overwhelming. I reached out on his website at night and Mark immediately called the next day. After speaking with Mark I knew he was the right person to represent me. The way he explains the process you get a sense that he's genuine. He is extremely efficient in providing the best possible outcome and gets started right away planning your defense. His method of handling my case and answering all my questions in a timely manner brought hope back into my life. He truly is out to help regular people with an affordable legal defense. Don't hesitate to contact Mark, he is the best!!!

Reliable, Professional, fair prices
Excellent experience from start to finish with Mark Deniz. He responded quickly and I felt he knew what he was doing from years of experience. Explained eveything that was going to happen with the process and clear any questions I had. I wanted to have my DUI expunged and that’s exactly what he made happen. He made sure we would be solid and prepared for our virtual meeting. Throughout the whole process I felt he cared about this as much as I did. Mark understood why I wanted this chapter in my life closed and ready for the new chapter to begin. Thank you again from the bottom of my heart.100 percent recommend and couldn’t have asked anyone else to make this happen but you.

Honest and trustworthy attorney!
I am beyond grateful that I hired attorney Mark Denise. From the first consult phone call, to the communication afterwards, it has all been seamless. I was charged with a misdemeanor hit and run after backing into a parked car. Attorney Mark not only got my case dismissed but he made it happen before my court appearance date. He even refunded me $1000 because it was resolved so quickly- if that doesn’t scream honesty, I don’t know what does! I can’t thank you enough Mark, for helping with this entire situation, you will always be the referral and go-to attorney if I ever need it!

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.

Absolutely Great
We got in touch with Mr. Deniz after searching for options related to cases mental health and finding an article/post expertly authored by Mr. Deniz. The particular set of laws were somewhat on the newer side, but Mr. Deniz was already experienced in the area. After a phone conversation about the details, Mr. Deniz took the case, walked us through the expectations, and stood with us every step of the way. We very appreciated all the work that Mr. Deniz and his office staff did while working on our case and would contact them again should we need to retain legal representation in the future!

The Best DUI Attorney
Mark was the first and only lawyer I contacted the day after my DUI arrest. Being from out of state under government orders I knew my time was limited before being sent back home to Washington. I needed a lawyer asap and didn’t have time to research or read any reviews. We never personally met and my entire case was handled via. Phone/Email. Mark and his team represented me from start to finish and made everything straight forward, simple, and stress free. His pricing was more than fair for how proactive and efficient he was at representing me and I know he will do the same for you. Thank You For Everything, -Kyle

Consult and HIRE Mark Lawrence!
I highly recommend Mark Deniz. He responded quickly and was very informative, caring and acted quickly to get ahead of the situation to persuade the District Attorney from not pressing charges. His flat fee schedule is reasonable and upfront, and although I was able to full pay, he does work with you on a payment plan. Again, I would highly recommend Mark Deniz and his office. I was not required to show up to arraignment and my case was dropped 2 weeks later.

Charges Dropped
Mark is phenomenal! He listens, answers questions, explains everything concisely, and he kept me clear on the steps along the way. Spoke to him one day, and 48 hours later, and some hustle, the charges were dropped and no court needed. My only prior experience with lawyers and courts was my divorce many years ago. Never had I imagined I’d be in any situation faced with such stress and intensity needing legal assistance this way.

The man with a plan
Mark Deniz is one of the best lawyers I have worked with. 5 months ago, I was really sad and down bad when I was arrested for solicitation of prostitution. For a couple of days, I felt like I was hopeless and frustrated because I knew if I got this misdemeanor, I was going to lose my job, so I was really sad. I started calling lawyers to see what I could do but every lawyer I talked to didn't convince me and a lot of them were out of my budget. Out of all the lawyers I called Mark was the only one who managed to make me smile after being sad for days. It was then that I knew Mark actually cares about his clients and was the right person to hire. Mark has a really strong personality and is ready to go to battle for you trust me. This guy is the definition of staying proactive. Mark always told me the best thing is to stay proactive throughout the case and he was not wrong. Long story short Mark managed to get me a 18 month diversion which is a lot better than getting a misdemeanor. Mark keeps his communication clear with his clients and is always open to answer questions. overall, I had a good experience with Mark he really saved my tail this time and I'm forever thankful for what he did for me. I know there is people out there going through something at the moment and my advice would be to call Mark Deniz. He also has a payment plan which is amazing because I don't know how I would make it with other expenses so that's another positive about Mark. Overall Mark is a man with a plan! thank you for everything Mark Deniz!

Dedicated Lawyer.
I received a DUI one morning from having a BAC (over the legal limit) from the night prior. My intent was not to drive intoxicated, and at the time I wasn't. I had no ground to fight it because the data showed I had alcohol in my system, drunk or not. Mark went to bat for me with dedication and a goal in mind. He listened to what I had to say and did his best to achieve what I wanted, even if it seemed challenging. Mark got my DUI reduced to reckless driving and later my probation was thrown out and my record expunged. His perseverance and can-do attitude made me confident I made the right choice. I can say the fee was equal if not less for the effort and work he put in. Mark does not do this to keep his pockets full but to assist those who need the law on their side.

Endorse Mark
Criminal defense Attorney | May 14
Relationship: Co-worker
"Mark has exceptional knowledge and experience in criminal law, having done numerous jury trials as a prosecutor. Mark thoroughly evaluates the strengths and weaknesses of his cases and his opponents. He also thinks outside of the box when necessary for his cases. Mark is respected in the legal community."
Criminal defense Attorney | Jun 09
Relationship: Worked together on matter
"Simply put, Mark Deniz is a legal specimen. From the opposite side of the courtroom to watching him work as a defense attorney, one thing is clear: he has an approach to lawyering that is unparalleled. His systematic, relentless preparation is unlike anything I've ever seen. The novelty of his ideas are far beyond the typical "textbook defense" approach that we see all too often (to the client's detriment). The prosecution simply cannot keep up with him. Mark Deniz is seven moves ahead on the chessboard and it's an absolute privilege to watch this attorney unfold his game-plan. He has literally re-invented the game. To use a sports analogy, Deniz is, frankly, the Billy Beane of criminal defense. Game-changer. Highest recommendation I can give an attorney."

I endorse this lawyer without hesitation."
Criminal defense Attorney | Dec 03
Relationship: Worked for lawyer
"I sat across the hall and worked for Mr. Deniz for over a year in prosecution. I can confidently say that you would be hard pressed to find a more learned, more experienced and more professional defense attorney in San Diego. This is especially true of DUI cases. He has worked criminal cases from every different angle forwards and backwards and much of that time has been in the San Diego courts. He also carries the rare quality of being genuinely caring and committed to all his clients. I attribute much of my knowledge as an attorney from what I learned from him - the Obi-Wan Kenobi to my Luke Skywalker (If I may use a pop culture reference for a moment). A top notch lawyer all the way around."
