  • Justin James McShane

    Attorney Middlebrook is the type of attorney that we should all strive to be. Impassioned, dedicated, over-prepared, gutsy, intelligent and in touch with the law and people. On a day-in and day-out basis, Attorney Middlebrook uses his well-earned national reputation, his considerable experience, and his vast knowledge to minimize or eliminate the consequences that may face a citizen among us who has been accused of a crime. It is through personal observation that I can attest to his skills. He is also utterly trustworthy and someone I call a friend. I therefore issue my highest and greatest form of endorsement to him.
