A New Hampshire native, in 2009 Kevin returned to New Hampshire to practice law in his home state after gaining education and experience around the country. He began his legal career at the Broward County Public Defender in Fort Lauderdale, Florida. Trial was a daily occurrence in this urban area where, for two years, Kevin spent every day in court and tried dozens of cases. He won acquittals in his first three cases, including two DWIs.

Moment in Time
Case is pending therefore I do not wish to share details. I thought that I had found an attorney to handle an emergency situation on the Tuesday morning after the Martin Luther King holiday. It is fortunate for me that this attorney was not available, as a result I found Mr. O'Keefe, and his paralegal Lisa Greenwaldt. I literally had one hour on this Tuesday morning to find an attorney, prior to arraignment. After several calls I located Attorney O'Keefe' and Lisa Greenwaldt. The kindness, caring and professionalism from both Lisa and Attorney O'Keefe was extraordinary. It was a "Moment in Time" because we only had minutes left as arraignment proceedings had now begun. Although Mr. Okeefe was in court and was engaged in other cases, he managed to get through to make the necessary call needed to support and move our case forward in a positive manner. Lisa worked hard to get this accomplished with Mr. O'Keefe. When a situation is handled with such grace, professionalism, patience and the respect for one's sense of urgency, the outcome can only be a positive one. So grateful, and this experience has given me a sense of peace. Look forward to your working with us. Thank You to Attorney O'Keefe and Lisa Greenwaldt. Sincerely, Ms. Martin

First time having to hire a lawyer and I hired the best!
I was pulled over for something that was overlooked 10 years ago. I was cited with a class A misdemeanor, despite the troopers insistence that if I just paid the reinstatement fee it would go away. I received a letter in the mail the Saturday before my case conference stating that I was facing jail time for something that I believed was taken care of 10 years ago. I had 4 days to find a lawyer. Kevin was the second lawyer I called as another firm couldn’t help on such short notice. He was quick listen and jump into action. He was able to get the misdemeanor dropped to a traffic level violation. Which meant zero jail time for me! He was quick to answer my emails and phone calls and did a good job preparing for my court date. I’m happy that I’m finally able to close those chapter of my life. Thank you Kevin for your patience and professionalism. I would recommend you to anyone who needed a criminal defense lawyer in NH.

He went above and beyond to help me even after my case was closed I am very grateful for him and his services that he provided to me. He helped in so many ways that no lawyer would ever do. I would highly recommend him to anyone.

Kevin okeefe was amazing. He really went to bat for me. I called him way too much and he always answered my calls and never complained. He stayed in touch with my mother and kept her updated. He did his best to stay in touch with community corrections and keep me informed.

He will always be honest with you about the merits of your case, but he will also fight for your rights with unequaled tenacity and passion. Attorney O'Keefe puts every ounce of his competitive drive into his cases. He is not only a skilled negotiator, but he is one of the premier trial attorneys in New Hampshire."

"Kevin O'Keefe is one of the best trial lawyers I know. I worked in the Public Defender's Office in Broward County, Florida with Kevin for several years. Kevin was one of the best attorneys in the office. He is extremely intelligent, but also is able to connect with juries in a way that few lawyers can. He is a genuinely nice person as well, and any client can know that Kevin can be trusted and will always treat them with respect, kindness and compassion. I would recommend Kevin to anybody looking for an attorney. I cannot give a higher recommendation than I am giving for Kevin."

Relationship: Fellow lawyer in community
"I have the pleasure of endorsing my friend and colleague Kevin O'Keefe. I met Kevin over 10 years ago when he began in the NH public defender's office. I found Kevin to be practical, hard working and open minded. I watched his interactions with other attorneys, prosecutors and judges and noticed how he was well prepared and always was able to think quickly when dealing with an adverse situation for his client. I felt that he was thinking of the next issue or question before everyone else saw it. Anyone who hires Kevin should feel confident that he or she will be well represented by an experienced, aggressive and well prepared attorney."
