Great Trial Lawyer

I retained Mark to got to trial for me to fight a difficult DUI arrest. Mark was knowledgeable, thorough, and exceedingly well prepared. He was eager to try my case, which I found very reassuring. I am a lawyer myself and the potential ramifications of the arrest would have been incredibly challe...nging for me both professionally and personally. Mark definitely understood and appreciated those ramifications and threw himself into preparing for my case and making sure that we put everything on the table necessary for a positive outcome. By the end of the trial, I felt relatively confident about the jury would return with a not guilty verdict. And that is exactly what happened! I highly recommend Mark and was very glad that I had him on my side.

You can breathe easy now, you've found the right person for the job.

Mark is a seasoned professional who has an excellent understanding of the law in addition to the fact he also has a very high degree of knowledge of the inner workings of the DAs office; the two things needed to advocate your success. I spoke with four attorneys in my research to find representation.... Through this process, I found that Mark had complete command of this daunting field from start to finish; because of his significant prior experience, he knew what he needed to do as well as what he needed me to do, and he kept me informed at all pertinent points in the arc of the case. By the time my court date came around, Mark had already negotiated with the DA to not file charges. Case closed. If you are like me, someone who has never dealt with the law, and you want to put your very best effort forward in hopes you'll never need to do so again, then Mark is the representation you can count on. I could not recommend him any higher.

Excellent Communication and Exceptional Results - Case Dismissed!

I cannot recommend Attorney Mark Geller highly enough. From the very first phone call, I knew I was in capable hands. He was incredibly proactive, anticipating next steps and layout out a clear strategy from day one. What stood out most was his exceptional communication; he provided instant replie...s to all of my questions, which gave me immense peace of mind during a stressful time. Mark worked incredibly intelligently to navigate the court system and ultimately achieved the best possible outcome: dismissal of my case. If you want an attorney who is sharp, deeply responsive, and genuinely fights for his clients, look no further. Thank you for your exceptional service!

Mark Geller gave us peace of mind and results!

My husband and I cannot recommend Mark Geller highly enough. We found ourselves facing an incredibly stressful and frightening situation involving domestic violence and public intoxication allegations stemming from a one-time incident that did not accurately reflect who he is or the reality of the ci...rcumstances. Because my husband has a strong reputation and a lot to lose, we knew we needed the right attorney. We spoke with several lawyers, but neither of us felt truly confident or comfortable until we spoke with Mark. From our very first conversation, it was clear why he has such an outstanding reputation. His experience as a former District Attorney gave us confidence that he understood exactly how these cases work and how to navigate the system effectively. What stood out most was Mark’s honesty and communication. He never made unrealistic promises or told us only what we wanted to hear. Instead, he gave us straightforward advice, realistic expectations, and a clear strategy. Throughout the entire process, he stayed ahead of every development, kept us informed, responded quickly, and made us feel supported during a very difficult time. In the end, Mark exceeded our expectations and achieved the best possible outcome; the case was completely dismissed. His preparation, knowledge, and proactive approach made all the difference. If you are looking for an attorney who is experienced, respected, honest, responsive, and truly dedicated to his clients, Mark Geller is worth every penny. He will fight for you, keep you informed, and do everything he can to achieve the best outcome possible. You simply cannot ask for more from a lawyer.

Excellent Attorney - Insightful/Well Connected

I highly recommend Mark as a defense attorney. From our first meeting, he brought clarity, strategy, and calm to an incredibly difficult situation. He quickly assessed the case, outlined a thoughtful path forward, and communicated every step with transparency and confidence. His background as a f...ormer District Attorney gives him a distinct advantage. He understands how cases are evaluated and prosecuted, which allowed him to anticipate challenges and build a strong, strategic approach. His preparation was thorough, his judgment sound, and his advocacy highly effective. Most importantly, Mark handled our case with professionalism and empathy, guiding it to the best possible outcome. I am deeply grateful for his expertise and would recommend him without hesitation.
