Dan Griffin is the flat out best in the business. As a Captain on the West Warwick Police Department I have personally had the opportunity to work with Dan and had cases against him. Nobody is more prepared, talented and responsive than he is. He has the respect of the judges, prosecutors and the law enforcement throughout the state. Anyone arrested or in need of a lawyer would do themselves a disservice by not calling him first.read more

Recent Wins at The Law Office of Daniel Griffin

DUI Defense – Avoiding Jail

January 2018: Client hired Dan Griffin after first going with another law firm and being told that his DUI case which resulted in a violation of his probation would result in him being incarcerated at the ACI.  Dan Griffin took over the case and reviewed every aspect of the car stop and arrest.  After only one court appearance, Dan was able to successfully negotiate a plea for his client that included no jail time and only minimum sanctions on the driving offenses.

Assault Charge

January 2018: Client was facing assault charges and any admissions or convictions would have resulted in termination from valuable employment.  After conducting his own investigation, Dan Griffin was able to convince the police, the prosecution and the court the case was dismissed.


December 2017: Client was charged with DUI and Refusal.  From the start of the case Dan Griffin maintained his client’s innocence in that the State had shabby evidence that she was actually operating her vehicle as they had alleged.  Dan tirelessly researched the matter and would not relent until both charges were dismissed the courts.  After two full hearings, both the criminal DUI and Refusal to Submit to a Chemical Test were dismissed in separate courts by separate judges.

DUI Defense – Diversionary Program Success

December 2017: Client was arrested for DUI/Refusal.  With Dan Griffin’s advocacy he was able to secure a place in a diversionary program, that he may not have normally been accepted.  Because of that  he is given the opportunity to avoid all penalties and fines and severe increases in insurance.
