About Mark
Biography
For more than 25 years, I’ve dedicated my career to defending good people caught in bad situations. From DUIs and traffic offenses to serious felony charges, I know how overwhelming the criminal justice system can feel when it seems like the odds are stacked against you. My job is to level the playing field and protect your rights every step of the way.
I’ve built strong working relationships with judges, prosecutors, and court staff throughout Southern California. Those connections, combined with my experience, give my clients a real advantage both inside and outside the courtroom. I understand when to negotiate and when to take a case to trial, and I’ve handled thousands of cases by using that judgment to get the best possible results.
Many attorneys across the state reach out to me for guidance on criminal and juvenile law. When you hire me, you get that experience directly. You’ll work with me personally from start to finish. I’ll take the time to understand your story, your goals, and what success looks like for you.
If you’ve been arrested or charged with a crime, you don’t have to face it alone. Let’s talk about your case and start moving forward.

Mark Gallagher is an exceptional lawyer
I cannot overstate how helpful Mark and his staff were for my case. His ability to listen and sympathize with my concerns gave me a lot of relief in a very challenging time in my life.

Many years of frustration finally has ended
After literally decades of dealing with a challenge that seemed to never go away, and being told by other attorneys that it was likely impossible to straighten out without flying cross country with no guarantee, it finally seems to be cleared up and taken care of. Though I live thousands of miles awa...

Saving Grace
Like many folks searching for a lawyer, I was in a pickle and had very little time to work with. I was soon to leave overseas for a summer program that I was enrolled in months back and would be gone almost the entire summer. With that said, my stress level was high, plus I was also tying up other lo...
