THE BEST!

Mr.Gutierrez handles cases with great expertise and care. He takes the time to listen and understand the situation in order to best access how to advise. His years of work pay off as he has great relationships with the court and prosecutors. I would definitely recommend him as a defense attorney to a...ll of my friends and family if they were ever in need, I know he will not view them as just another paycheck.

Relationship: Worked together on matter

"The first time I met Mr. Gutierrez was at court a few years back. We were working together on a case, and he was able to convince the District Attorney to reconsider their previous offer of a felony and significant jail time, to no jail time and a misdemeanor. What stood out more than the outcome, however, was how Mr. Gutierrez spoke with his client. He was calm, respectful, and took the time to explain exactly what was happening. Since then I have observed Mr. Gutierrez handle a variety of matters in court. Each time, what stands out the most, is the way he interacts with his clients. In any case, but especially a criminal one, having the right attorney can make all the difference. And no matter the outcome, you want an attorney who is by your side and keeps you informed, like Mr. Gutierrez."

Relationship: Worked together on matter

"I had the privilege of working alongside attorney Geronimo Gutierrez IV in downtown Los Angeles, and I highly recommend him. Your outcome in a criminal case depends greatly on someone who will: (1) challenge the evidence, (2) dig in, and (3) fight alongside you. Geronimo Gutierrez IV is that kind of lawyer. Whether you have been wrongly accused, grossly overcharged, or if you simply need someone to present "factors in mitigation" and inform the District Attorney's Office about the totality of the circumstances, Geronimo is the right lawyer for you. What's more, he is fluent in English and Spanish -- something that can make a real difference for so many families. I recommend him without hesitation."

  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
