When you are charged or being investigated for a serious crime you need the very best criminal defense attorney out there. Dennis Boyle has been ranked among the top ten criminal defense attorneys nationally and is the recipient of numerous awards, including an American Bar Association award for Professional Merit. He also has the highest ranking available—AV—from Martindale Hubble and has been recognized multiple times as a Super Lawyer in both Pennsylvania and the District of Columbia.

Like many top defense attorneys, Dennis began his career as a prosecutor. He began his career as a Navy Judge Advocate, where he served in a variety of positions before retiring as a Commander in the U.S. Naval Reserve. He was a Commissioner with the Navy-Marine Court of Criminal Appeals at the time of his retirement. As a civilian, he has been a First Assistant District Attorney, Special Assistant United States Attorney and, most recently, a partner with a national AmLaw 100 law firm.

For the past twenty years, however, he has dedicated his practice to criminal defense, particularly white collar criminal defense. Unlike other white-collar attorneys who have not tried a case in years or decades, Dennis believes in defending the case even if it means going to trial. Over the past 30 years, he has tried more than 200 jury trials and has won numerous acquittals. He was won four out of five homicide cases that he took to trial and has won acquittals in mortgage fraud and criminal RICO cases. In fact, since becoming a criminal defense counsel in 1996, he has only lost four jury trials in state court.

The successful defense of a case, however, does not begin at trial. A successful defense begins with proper investigation and preparation. Avoiding charges in the first place is frequently the best outcome for a client. The government can frequently be convinced not to file charges if defense counsel understands that facts and the government’s allegations. This opportunity can be lost, however, if the client does not retain the right legal counsel early in the investigation. If another law firm is conducting an “internal investigation,” executives and senior employees should understand that although the company’s counsel are not government attorneys, they may be agents of the government and that they too need their own independent counsel.

The same skills that make Dennis an outstanding criminal defense attorney also make him an excellent advocate for the victims of fraud or other business torts. He is an active member of the Public Investors Arbitration Bar Association (PIABA) and represents individuals who have been the victims of securities frauds by stock brokers and investment advisors. With more than 30 years investigating, prosecuting and representing people charged with fraud or fraud-type conduct, he understands complex financial transactions and what conduct does or does not constitute fraud.
