Exceptional Criminal Defense Attorney - Thorough, Professional & Reassuring

As someone who had never encountered legal issues before, facing my first criminal case was scary. After interviewing several experienced lawyers in San Jose, I was referred to Sam. From our first consultation, I knew he could help me achieve the best possible outcome, and he indeed accomplished that.... He thoroughly explained the legal process, terminology, and potential scenarios, providing reassurance throughout. Not only is he a quick and reliable communicator, but he also handled my case professionally and diligently. Hopefully, I won't need his services again anytime soon, but if I or an acquaintance ever do, Sam will definitely be my top recommendation.

Review by Joe :)

I am incredibly grateful to have had Sam represent me in my case. From the very beginning, he and his assistant Debra demonstrated an exceptional level of professionalism, confidentiality, dedication, and expertise that truly set him apart. Thanks to Sam, my case was rejected, and I was able to se...cure a Certificate of Factual Innocence. This outcome has profoundly impacted my life and I cannot thank him enough for his hard work and commitment. Throughout the entire process, Sam / Debra were always available to answer my questions, provide reassurance, and keep me informed about the progress of my case. He took the time to explain complex legal concepts in a way I could understand, which made a world of difference during such a stressful time. I highly recommend Sam to anyone in need of legal representation. His network, expertise, dedication, and compassion are truly unmatched, and I am forever grateful for the positive outcome he achieved for me. Thank you, Sam, for everything you have done!

Highly recommend! - Criminal defense - Outstanding, determined, and caring

Mr. Polverino is extremely competent and knowledgeable in complicated criminal defense cases focusing mostly on Santa Clara County. My case being excellently conducted from the first court date reduced charges to misdemeanor, to eventually dismissal after multiple court representations over the past ...seven months. He’s very calm and professional, and promptly responsive either personally by email or through his assistant Debra. I remember he personally called me back the same day after I contacted his office and left a voice message. It was a no brainer decision to hire Mr. Polverino after consulting/interviewing seven attorneys who all specialize in similar criminal defense cases. All in all Sam is simply the best!

Extremely knowledgeable, calm, and geniunely caring

I was facing a serious felony charge that had potential to get even worse. Knowing this, I knew that I required first-rate legal representation. I consulted with several lawyers about the case, and after reviewing the options, it was clear as day that Sam was the best choice. I was referred to him by... a family friend who practiced in a different type of law, and I am lucky he referred me. Not only did Sam have expert knowledge about the crime that I was being charged for, but he also knew the ins and outs of the court where my case was filed at thanks to his extensive experience. He was able to create a brilliant strategy that looked at every possible angle, which immediately put my worries at ease. In addition to this, he kept consistent communication with me throughout the entire case. I was never left wondering or confused about anything, because Sam and his office staff would always keep me in the loop with emails, letters, and phone calls. I won't go into the specifics, but I was facing a felony charge with several years in state prison. Some details of the case could have made the situation much worse, and I could have faced even more time. Thanks to Sam, I type this as a free man who never saw the inside of that prison cell. Reduced to a misdemeanor, 30 days of house arrest, no probation, cleared record after a year. When I must face the judge, there is no one else I would rather have by my side than Sam.

Couldn't be more grateful to this attorney

Sam Polverino is a God sent lawyer! We called about 20 lawyers before we found him. We sat down with him on a Friday afternoon regarding a possible sex assault charge. He knew which DA prosecutor our case would be sent to. He made a call to the district attorney office and to the investigator right i...n front of us and quickly got the details of the case and how the prosecution approaches it. The investigator was willing to talk to him because he knew him from a previous case. What a relief after two weeks of being in darkness! Luckily for us, it sounded that the case was too weak for the DA to file charges. If you're looking for a criminal defense attorney, look no further. After having spoken with about 20 attorneys, we knew what we were looking for - knowledgable, professional and empathetic. Sam is all of that. We highly recommend him! It also looks like he is highly regarded among his colleagues in the community. We couldn't be more grateful. If you or your family are going through stress of facing criminal charges, you need an honest, proactive and knowledgable attorney. Thankfully, there is one like that.
