Great Help

Richard handled my case with professional grace. Throughout the process, both he and Kristen were helpful in explaining everything.

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.

Scott H.

In September 2024, I received notice of a professional ethics complaint against my medical license before the New Hampshire Office of Professional Licensure and Certification (OPLC). I retained Attorney Doty and her team to represent me in what was essentially a civil ethics matter. By November 2024,... Attorney Doty had successfully negotiated a settlement that preserved my professional standing and left no significant marks on my record. Throughout the process, Attorney Doty was exceptionally helpful, maintaining clear and consistent communication. She promptly returned my phone calls and emails, keeping me up-to-date every step of the way. More importantly, her and her team's careful handling of the case ensured the matter was resolved within the terms of her initial retainer, reflecting both efficiency and cost-effectiveness. I am grateful for the outstanding service and outcome delivered by Attorney Doty, and I would highly recommend her to anyone facing a similar professional licensing challenge.

I chose to have Richard represent me and I couldn’t have asked for a better outcome. You can tell he knows what he’s doing and cares about his clients.

"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."
