Philip T. Carroll


Philip T. Carroll has helped clients solve problems in the fields of construction, product liability, and subrogation. Clients have turned to Philip to handle construction disputes, involving under designed and defectively constructed buildings, failures in life safety systems, product failures, transportation and cargo losses, and industrial accidents. 

Philip chairs Cozen O'Connor's Material Task Force. This task force was formed due to the increasing globalization of the world market. Material failures in engineered plastics, woods, metals, polymers, bio-polymers, and other composites are identified, evaluated, and litigated. Philip has personally worked on various material issues, including failures involving thermoplastics and thermosetting polymers such as CPVC, Acetal, PVC, ABS, Nylon 6/6, PEX, and polypropylene; metals such as brass, zinc, and copper; manmade woods and insulators including SIPS & EPS, and cellulous insulation.

Philip is also a frequent lecturer and blogger on construction, product liability, and subrogation issues, including most recently:

• Why Plastic Parts Fail

• The Revolution in Building Materials, Plastics - Innovation or Ignition?

• Tools for Effective Case Themeing

• Development of the Difficult Product Liability Case

• Say Hello to MY Little Friends - Getting Manufacturers Attention Through Aggregation Of Claims

Philip was involved in The National Association of Subrogation Professionals (NASP). Philip served as the co-chair of the General Practice Section of NASP in 1995 and 1996; co-chair of NASP's Litigation Skills Conference in 2007; and the Executive Committee for NASP's Litigation Skills Conference. He is also involved locally, serving as a committee member of the Michigan Chapter of NASP. In 2011 Philip assumed a position on the NASP board of directors.

Philip attended SUNY-Stony Brook, where he received his Bachelor of Arts in 1993.  He then attended University of Detroit Mercy School of Law where he received his J.D. in 1997.
