Mr. McDermott has defended all kinds of criminal cases, including major felonies, misdemeanors and traffic offenses. His career has included several acquittals or successful dispositions or dismissals of cases involving homicide, assault, sexual assault, drugs, kidnapping, and alcohol-related offenses. He strives to have serious criminal charges dismissed prior to trial and to assist his clients to avoid prosecution when they are still under investigation. He is an ardent believer that everyone who is criminally charged should have an excellent attorney to ensure a fair in light of the power of the criminal justice system. This can only be achieved by vigorous and professional representation of a client, both as the client’s advisor outside the courtroom and his or her stalwart advocate inside the courtroom.
