John C. Cahalan is a member of Plunkett Cooney's Transportation Law Practice Group. Prior to joining the firm, he served as in-house counsel for an international insurance provider.

Mr. Cahalan focuses his practice in the areas of motor vehicle liability, Personal Injury Protection (PIP) insurance, medical fraud investigations, attendant care disputes and extra-contractual litigation. These matters typically include first- and third-party liability, as well as claims involving uninsured and under-insured motorists (UM/UIM). He also has expertise in the areas of personal injury, premises liability and injuries arising from the ownership of pets.

Mr. Cahalan's previous in-house counsel experience provides him with a unique perspective on the importance of the insurance provider/policyholder relationship and the need for outside counsel to focus on such service imperatives as legal project management.
