Unmatched legal expertise and unwavering dedication - Kellen is the go-to lawyer for even the most complex cases.

As one of Kellen's clients, I can attest to his unparalleled legal expertise and dedication to his clients' causes. Kellen possesses a unique combination of creativity, intelligence, and compassion, which allows him to approach every case with a fresh perspective and develop innovative solutions. ...In my own custody case, which was complicated by mental health and problematic co-parenting issues, Kellen's strategic approach proved to be the key to our success. Despite the seemingly insurmountable challenges, Kellen was able to analyze the nuances of the case and identify the strengths and weaknesses of our position. With his vast experience and comprehensive knowledge of the law, Kellen advised us on the best course of action and tirelessly pursued our case with determination and tenacity. Thanks to his exceptional legal representation, we emerged victorious in a case that had seemed hopeless. Overall, I cannot recommend Kellen enough as a legal counsel. His brilliance, insightfulness, and strategic approach are unparalleled, and his unwavering commitment to his clients' causes is truly remarkable. If you are in need of a lawyer who will fight tirelessly on your behalf, Kellen is the one to call.

My husband and I couldn’t be happier with Mr.O’brien’s services & help with our step parent adoption process . He made us feel confident that we had the right team by our side for this process and now I couldn’t agree more . Mr.O’Brien is very dedicated to his clients and work . He made what we thoug...ht would be a stressful process a smooth and positive experience . Mr.O’Brien always took his time to explain and prepare us to the best of his ability for our case .

Couldn't have asked for more!

Divorce is never easy, but rest assured, with Kellen you will be in good hands. From the very first call, to the very end, Kellen made himself available for me and was very thorough. He took the time to make sure I understood what was happening and had a great way of explaining things. He is extremel...y genuine and makes you feel very supported during the whole process. I honestly have nothing but positive comments to say about Kellen O' Brien, and am so glad I picked him to represent my case.

Highly recommend Attorney O'brien!

I hired Attorney O'brien to handle a highly contested property line dispute. Prior to hiring Attorney O'brien I had consulted multiple other attorneys that I did not feel confident in hiring. Attorney O'brien is everything that you would want to have as an attorney. He is knowledgeable, articulate..., focused, approachable and caring. Ultimately, he gives you the confidence that you have someone in your corner that has your back! Over the year and half Attorney O'brien worked on our case he was exceedingly patient with my questions and ideas and always spoke to me with respect. In the end my case went to trial and I cannot say enough about Attorney O'brien and his confident and cool demeanor, his ability to maintain authoritative presence in the courtroom and ability to think on his feet. All of this showed to me the detail and care that it took to prepare the case for trial. Without a doubt Attorney O'brien is talented attorney and fantastic attorney to take a case to trial. It is clear he holds himself and his work at a high standard and cares for his clients. I would definitely hire him again without a second thought.
