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.

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!

Very experienced, genuine, and kind!

I was involved in a domestic violent case, and I found Sam through online research. I talked to a few other lawyers before him, but I knew I needed to hire Sam after our initial consultation. We met face to face at his office. He carefully listened to my experience and walked me through the legal pro...cess. He is very experienced as he shared a lot more details about the District Attorney office than the other lawyers did, and he knows the current best way of convincing the DA to drop the case. He is also very genuine and down-to-earth. When I ask uncertain questions, he focuses on facts and does not over-promise anything. His legal pricing is competitive among all candidates, and when I asked if there is any room for discount, he honestly told me this was the lowest he would charge on a DA case. After I hired him, Sam and his assistant Debra answered all the questions I came up with. Luckily, my case was rejected before a preliminary hearing, and Sam voluntarily refunded two thirds of the legal fee and helped me request a detention certificate and sealed my arrest record. It was unbelievable. Honestly, I don't want to see any lawyers again. But if I get myself into troubles again, I wouldn't hesitate a second to hire Sam.

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.

Don't waste time call him now!!

I've had to hire many lawyers to defend me, I've also sat down with more lawyers in consultation than I could count. I instantly knew that Mr. Polverino was the one I was looking for. In fact "Sam" as he prefers, was the only lawyer to tell me in my particular case and my charges that I had a fighti...ng chance. The other 5 I had sat down with all said it was in my best interest to plead guilty based on the police reports. No jail time, no probation, 16 hour online course, was the outcome of my case. In my opinion when you run into an issue and hiring a lawyer is a necessity well it can get quite expensive lawyers are not cheap, and neither is our freedom. I was blown away when we agreed on the price for Sam to represent me. Not only was the price exceptionally fair, but compared to the other numbers those lawyers i sat down with. Well let's just say they wanted double. For everything Sam did for me in my case and the result I recieved. I'm extremely thankful! Lastly, Ms. Debra his assistant is the most amazing helpful woman to make the experience even smoother. He's lucky to have her on his team. I truly hope I never have to call them again, but if I did I have his business contact next to my driver license.

He is smart, determined and a pleasure to deal with. He clearly has the respect of the prosecutor's office, which was a major factor in the outcome. I would use him again in a heartbeat."
