path to prison

before I paid him money, he told me it's difficult for DA to prove I was guilty because no evidence, after I paid him a flat fee, he told me that it's difficult for me to prove I was innocent because no evidence, and suggested me to plea guilty, otherwise I might stay in prison for a very long time, ...and I could not survive in the prison. After that, it's very difficult to connect with him unless he want me to paid a bill. Finally, he asked me to pay an unreasonable bill, then he would get a great deal for me, I refused to plea guilty or pay the unreasonable bill, then he withdrew. At the beginning, he told me the bill was $1200, I agreed; later, he told me the bill was $1800 because the expert need to travel from east bay, $600 for the travel fee, I asked him to hire an local expert, he refused; later, he told me the bill was $3100. I paid $1800, but refused to paid the additional $1300. After 2 years, my case was dismissed. If you search his name in Santa Clara court's website, you may find out that he is working on 100+ cases at the same time, he won't have enough time to help his clients even if he wants

This description is untrue and lacks important context. This gentleman hired me on this case approximately two years ago. After reviewing the evidence in his case, I hired an expert with his consent and direction. When the expert provided us with the confidential results, he refused to pay for the expert’s fees. I paid the expert and withdrew from the case. This was before any evidentiary hearings were conducted. I wish him well and hope the District Attorney does not refile the case against him. I do not accept cases unless I can devote to my client the time needed to defend the case.

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.

very unethical attorney

I hired Mr. Polverino to defend me in criminal court in 2022-2024. Mr. Sam Polverino is among the worst criminal lawyers I have ever encountered. Prior to receiving your money, Mr. Polverino speaks in a professional manner. When he gets your pay, he will ignore you. As a lawyer, Mr. Sam Polverino lac...ks a strong work ethic. His time is not invested in the case. He lacks experience and is careless. Worst of all, he disregarded his clients while taking their money. When I required Mr. Polverino's help, he was unavailable. I called, texted, and emailed a lot, but I was largely ignored. I wanted to beg for help, but they turned me away. His secretary, Debra, was almost the same. Mr. Sam Polverino is not someone I would suggest to others. Avoid this law firm at all cost.

This description is untrue and lacks important context. After having his case dismissed the District Attorney refilled the case. He was represented by two different lawyers after I withdrew from the case before any evidentiary hearing was held. On May 19, 2025 he resolved his case for the identical offer I negotiated in his behalf.

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.

Skilled, Dedicated, and Trusted

I began my search with a list of several criminal law specialists because I wanted to hire someone I could trust with knowing criminal law. Someone who is well experienced in criminal law, criminal courts, and who knows what to expect when an individual is accused of a crime. After dialing the Offi...ce of Sam Polverino, I was able to speak directly to him about my situation, which frankly made me panic because of the severity and nature of the allegation. As I spoke with Mr. Polverino, he carefully listened to every detail over the phone given that I had not yet scheduled the first appointment. I was highly impressed by his attentiveness and caring nature. After we spoke on the phone, we scheduled to meet, and during the first meeting, I knew I wanted to hire Mr. Polverino. So, I felt I could trust him, and I hired him as my attorney. He began with a general discussion about crimes, and how the criminal system works. He helped me understand how this situation could affect me, and he also began to strategize in ways that could help me resolve the matter. His experience as a specialist was evident in the way he knew case law within the penal code. Mr. Polverino knew exactly how to deal with my situation after we spoke, but I was able to see his professionalism the minute I hired him. He kept in constant communication whenever there was information that needed to be exchanged. Even after business office hours and weekends when I would have last minute questions, he would respond when he made himself available. Not to mention, during hard times, when I did not know what to expect, Mr. Polverino’s positive energy and good aura helped me stay positive. After my first experience in court, I learned how well respected he is in the legal community. As his client, he treated me with great respect and dignity. Although it took over a year to resolve my case, Mr. Polverino consistently worked toward justice- at finding the truth. With his expertise at hand, and his skillful team of professionals, my case was dismissed. I was finally able to move on with my life. Hence, I highly recommend Mr. Polverino to you, if you are troubled by what you are facing or if you have lost faith in the criminal justice system. Hire Mr. Polverino, a lawyer you can trust!
