Lawyer who truly shows up

When the unthinkable happened and I was booked on a wrongfully accused serious charge, Mark stepped in with a calm presence, clarity, and real compassion. From our very first conversation, he helped me understand what was happening, what mattered, and what didn’t. He didn’t just give legal advice, he... helped me steady myself when I was overwhelmed trying to mitigate the ramifications of such an event. He was steady, thoughtful, and incredibly responsive. He walked me through each step, explained the process in plain language, and never once made me feel rushed or dismissed (I had a LOT of questions). I always felt like he genuinely cared about the outcome and about me as a person. What really stood out was his ability to engage with the District Attorney and guide the situation, pushed back on assumptions, and let the truth prevaol. His approach was quiet, strategic, and effective as ultimately the DA declined to file any charges, and I was able to move forward with my life, my name, and my future intact. I didn’t think that was possible at the start, but his work made it happen within days. Mark didn’t just handle a legal matter, he helped me through one of the hardest moments of my life and gave me a chance to breathe again. If you ever find yourself in a situation that feels bigger than you or overwhelming to navigate, he is someone you want in your corner. I’m genuinely grateful for his help.

Excellent Attorney

Mark is an excellent attorney who is well versed in all aspects of the law. As a retired law enforcement executive with 35 years experience I would highly recommend Mark to anyone seeking professional highly competent representation.

Outstanding Legal Support When I Needed It Most

I hired Mark to help me with a DA matter, and I couldn’t be more grateful for his support. From the very beginning, he was extremely communicative, keeping me informed every step of the way. What really stood out was how he made me feel—after days of stress and anxiety, he gave me confidence and a se...nse of calm that I truly needed. Professional, reliable, and genuinely caring. I highly recommend him to anyone who needs a lawyer who will not only handle the case with skill but also ease your worries through the process!

He’s not just your lawyer. He’s your leverage.

Mark Geller is exactly the kind of attorney you hope you’ll never need, but feel incredibly lucky to find if you do. I recommend him without hesitation. From our first call, he was sharp, measured, and entirely unshaken. He immediately understood both the legal and reputational implications of my ...situation and moved swiftly to present a compelling case to the City Attorney. His proactive strategy neutralized the risk and shifted the entire trajectory of this matter - and quite frankly, my life). Because of his judgment, reputation, and the respect he commands, the City Attorney declined to file charges. I put my career and reputation in his hands. He protected both with ruthless clarity. If you’re facing reputational or professional exposure, retain him.

Amazing Service

Mark walked us through the entire process. He answered all of our questions, and we had a lot of them. As we had never been in this position before. His guidance and understanding of what to do and what we were going through was white glove service. Thank you Mark...
