My life turned upside down

My life turned upside down when I was informed of a dated outstanding warrant. I was out of state and needed a great attorney to help me through this nightmare. Richard Guerriero’s name came up several times. I contacted Richard’s firm late on a Friday afternoon. He reached back out to me later t...hat night and explained what I needed to do and how we would coordinate my return to New Hampshire. The charges were serious and carried significant prison time if convicted. At our first meeting, Richard explained the charges, possible sentences, and how we would move forward. Richard continually re-enforced this was a process. He was very clear, very direct, and always focused on facts. Richard and his team (Oliver and Kristen) worked diligently on building a defense and how our case would move forward. As we moved forward and the facts were presented by Richard to the State and the charges were dismissed!!! I cannot say enough about Richard and his team. Richard’s 40 years of criminal defense experience, his respect within the New Hampshire Court system, and his commitment to help his clients is second to none. I would HIGHLY RECOMMEND Richard Guerriero and his firm – They helped me regain my life.

Richard Guerriero Review

Richard represented me on a DUI charge. He was very supportive, understanding and great at his job! We had a positive outcome and I am extremely grateful for his support and dedication to my case.

Honest, Proffessional, Gets the Job Done

I am beyond pleased with Richard and his results. He has a great history in criminal defense and it shows. I would highly recommend anyone to Richard. His fees are very reasonable for the value he brings. For me, what was most important was his honesty and trust level. I felt comfortable discussing m...y case with Richard and knew he was working his hardest for a not guilty verdict, which was our outcome. Richard is also very easy to access by phone or email and overall, just a truly great experience out of a bad one.

A True and Honest Lawyer

"Not guilty" was the best thing I heard in a year and a half. I was originally charged with Manslaughter, then charged with an "alternative" charge of Negligent Homicide. This all started with a horrible accident with a death resulting. I sought the advice of two friends who had been involved in... the NH legal system for many years. They recommended Richard Guerriero for a very serious criminal case. I met with Richard on a Sunday and could clearly see that he was a person of integrity. I thankfully retained his services. Richard worked long and hard to get what prosecution thought was good key evidence thrown out. He found an expert witness who refuted the validity of that evidence. Richard filed several long motions objecting to the evidence. After a two-day hearing, before the trial, the judge threw that evidence out of the case. This is what led to the prosecution dropping the manslaughter charge just before the start of the trial. We went to trial on the negligent homicide charge. Richard and his law partner, Ted, were completely prepared for trial and fought for me all the way. After three days of trial, the jury quickly returned a not guilty verdict. I cannot say enough good about Richard, Ted, Kristen, and all the other staff that worked so hard for me. I am not sure if I could have made it through without them. Richard, Ted, and Kristen are people I would very much like to call friends. I without a doubt recommend this team to anyone who is in need of legal representation in any criminal case. HNA

"When it comes to intelligence, persistence, zealousness, ethics, and commitment to the client, I am not sure I have ever met a lawyer who has these all of these traits in such impressive combination. Richard is the state's go-to person for complex criminal defense . . . he is painstakingly thorough, adept at developing factual and legal defenses, and extremely good at sentencing advocacy. If I or a loved one were in trouble, Richard might well be my first call."

Relationship: Worked for lawyer

"You will not find a smarter, more well respected lawyer than Richard Guerriero. I was a new public defender in 2008, when Richard was preparing a very high profile capital murder case for trial. What I saw in Richard was the very best role model for a new lawyer and I was lucky to have his example. Richard is brilliant, meticulous, and dedicated to his clients. Further, he has the unmatched respect of the legal community, including judges and prosecutors. If you walk into court with Richard, you can be sure that you are with the highest quality lawyer. If my closest family member needed representation, I would send them to Richard before anyone else."
