Brian Cullen

Now approaching his 21st year of practice, Brian has gone from mega-firm, Boston’s Bingham McCutchen, to prosecutor as Chief of the Narcotics Unit in the Suffolk County District Attorney’s Office and back to private practice. At CullenCollimore, he has extended his appellate and trial practice to federal court and now regularly tries cases before juries in both state and federal courts in New Hampshire and Massachusetts.

In 2013 alone, Brian successfully concluded three jury trials, including a federal civil rights case in the United States District Court, securing defense verdicts for his clients in all three. The trial success complemented a number of appellate victories and pre-trial dismissals and summary judgments. Since 2007, no New Hampshire lawyer has successfully tried more non-prisoner civil cases to jury in our federal court.

Brian’s trial practice includes:

  • Successfully defending a former shareholder and company president against trade secrets and unfair competition claims following the client’s entry into competition with his former colleagues.
  • Favorably resolving a high-damages products liability case by avoiding a market share approach to damages through expert review of metal castings.
  • Defending employers in claims of age and disability discrimination before state and federal administrative bodies and courts.
  • Defending police officers in federal and state courts from claims of wrongful arrest, excessive force, and First Amendment violations in cases ranging from political protests to drug arrests.
  • Protecting good faith investors in a Ponzi scheme from claw-back litigation initiated by state officials.
  • Securing over a dozen defense verdicts in favor of retailers facing premises liability claims.
As achieving victory at the trial level may only be half the battle, Brian also has a regular appellate practice, including:
  • Multiple appearances before the First Circuit Court of Appeals, securing affirmance of numerous successful summary judgment motions in cases ranging from wrongful termination to civil rights claims.
  • Filing Amicus brief on behalf of state association of police chiefs on challenge to probable cause standard.
  • Representing the state in over 35 criminal appeals, including seven first degree murder cases, before the Massachusetts Supreme Judicial Court.
Brian received his B.A. from Bates College in 1989 and J.D., magna cum laude, from Villanova University School of Law in 1994. An avid skier and hiker and runner, Brian has completed two marathons (Boston, Philadelphia) and is looking forward to completing New Hampshire’s 4000 footers this year. Brian is a 2014 participant in Leadership Greater Nashua and a member of the Board of Directors for the Nashua Soup Kitchen and Shelter.
