About me

Diane Fenner graduated from the University of Pennsylvania Law School. She received her Bachelor of Arts degree with honors from Barnard College, and also has a Ph.D. in psychology from Columbia University. Diane has been practicing law since 1983, and was involved in jury selection in high profile cases.

After 4 years at the prestigious Philadelphia-based defense firm of Pepper Hamilton, Diane switched to a practice exclusively devoted to the representation of injured individuals. As such, she has practiced in various areas of personal injury, including medical malpractice, automobile accidents, premises liability, and product liability.

At the present time, her Philadelphia practice is devoted primarily to workers' compensation matters, where she represents both injured workers and medical providers who are denied payment for their treatment. She has lectured at workers' compensation seminars. Most recently, she spoke at the Philadelphia Bar Association on the subject of undocumented workers' rights in the workers' compensation system. She has a national practice specializing in the representation of people injured as a result of pharmaceutical products.

She writes the chapter on the six volume series entitled "Drugs and Medical Devises" published by the American Association of Justice and was involved extensively in Hormone Therapy (Prempro) litigation.

On a personal note, Diane is married and has five children, ages 33 to 18. She has been practicing full time since graduating from law school. In her spare time, Diane is involved in activities relating to the prevention of domestic violence and has served as a hot line volunteer for several years.

Diane also has the following qualifications:

  • Treasurer, Workers' Compensation Section of the Philadelphia Bar Association

  • Certified Specialist in Workers' Compensation

  • Lecturer, Philadelphia Bar Association
