Law Officers of Myers and Proctor P.A.
“As an attorney, Dennis O’Brien is fearless. He has an innate ability to identify the strong points and weak points of a case from the early going and is seldom “surprised” or sandbagged by the opposition.
He has a remarkable memory for detail and can always tell you in exactly which posture a case sits. He tries a case in the same manner in which he plays hockey—like a freight train coming at you.”
Kenneth M. Levine and Associates
“What sticks out in my mind about Dennis is that he is a smart, tough lawyer who gives everything he has for his clients. He is a man of integrity. Dennis has always conducted himself with a sense of integrity and dignity that is rarely found in our profession.
Dennis is one of the last of a breed that still believes his word and handshake are his bond. Dennis is fearless. If he believes in the cause he is not afraid to take on the biggest opponents such as doctors, hospitals and corporations. If Dennis believes in the clients and the cause he is not afraid of the fight, no matter who the opponent.
The practice of law is about more than money to Dennis. To him, the practice of law is about justice. He sees himself as the person responsible to even the score and help those that cannot help themselves fight the more powerful.”
