Kathleen M. Guilfoyle focuses her practice on aviation/aerospace defense, products liability and drug and medical device defense.

Kathy represents several airlines, airport authorities, manufacturers, ground handling companies and airport and airline contractors in cases pending throughout the state and federal courts of Massachusetts, Rhode Island, New Hampshire, Connecticut and Vermont. This litigation includes the defense of claims involving personal injury and death, premises liability, the Air Carrier Access  Act, discrimination, kidnapping and general commercial litigation. Kathy successfully argued dispositive motions seeking to limit damages or preclude a liability finding under the Montreal Convention and other treaties. Kathy and her firm represented one of the non-carrier airlines in the litigation pending in the United States District Court for the Southern District of New York arising out of the terrorist attacks of September 11th. In this litigation, she also worked on responding to requests for information from the Kean Commission, and participated in non-public witness interviews of various airline personnel by Kean Commission staffers. Kathy was a presenter at the International Aviation Womens Association Annual Conferences in Lisbon and San Francisco and multiple ACI Aviation Conferences in Boston. Kathy also participated in a panel on crisis response and the lessons learned by the airlines at DRI’s Corporate Counsel Roundtable.  Most recently, Kathy was a speaker at SMU Air and Law Forum in Dallas, Texas.

In addition to her aviation/aerospace practice, Kathy is actively involved in defense of drug and medical device manufacturers, trucking litigation, and the defense of a variety of products liability cases involving such diverse products as printing presses, heaters, toys, food and medication. She has handled cases in these fields from pre-suit to verdict. She has also handled the defense of various environmental claims for fuel suppliers involving 21E claims, releases, propane tank explosions and faulty regulators.
