  • James O Ruane

    I am the current president of the Connecticut Criminal Defense Lawyers Association and I definitely endorse Attorney Barrett for their work defending people charged with criminal offenses in Connecticut. Attorney Barrett is a tireless fighter for the accused and zealously defends his/her clients. If you are seeking an attorney for help with a criminal case, you have found a good one in Attorney Barrett.

  • Mark Daniel Sherman

    Attorney Barrett and his firm routinely provide top tier family law services to my Connecticut clients, throughout the State. He, capably and cost-efficiently, fights for clients during divorce proceedings as well as in post-dissolution matters. I have no hesitation in recommending Sean and his firm to anyone needing a Connecticut family lawyer.
