James J. Waldenberger, a partner at Kline & Specter, is an experienced litigator who has a wealth of hands-on experience in personal injury cases that has resulted in an impressive record of legal victories.

Since joining Kline & Specter in 2007, Waldenberger has obtained a litany of seven-figure verdicts and settlements in practice areas ranging from medical malpractice, product liability, premises liability, auto accidents, workplace injury and child sexual abuse.

In his latest case, Waldenberger in 2024 reached a $32 million settlement with Hahnemann University Hospital for the family of a child born severely brain damaged after doctors delayed performing a cesarean section. The boy, now nine years old, is quadriplegic, suffers severe communication impairment and must be nourished using a feeding tube.

Waldenberger's wide-ranging record of victories has earned him inclusion in the 2017-2024 editions of the peer-review publication Best Lawyers in America*.

In addition to the many legal victories he has earned, Waldenberger plays an essential role at the firm helping his younger colleagues not only with their cases but also in managing their work/personal lives. This earned him selection as a finalist in The Legal Intelligencer's award for Mentor of the Year in 2023.

In 2023, Waldenberger obtained a $6.5 million settlement with Piazza Nissan of Ardmore, Pa., for the family of an 89-year-old woman who was struck and killed as she walked along the sidewalk by a company driver as his vehicle exited the dealership. (Read article)

A year earlier, Waldenberger represented a seven-year-old child in litigation that resulted in a $30 million settlement and safety improvements in a case involving an auto accident with a commercial vehicle in Delaware County, Pa., causing the child to suffer a severe brain injury.

In a verdict in which he was lead counsel, Waldenberger won a $5.5 million jury award in Philadelphia Common Pleas Court for a mentally disabled man who was rendered a quadriplegic when the commercial van in which he was riding struck a utility pole.

He won a $3 million Philadelphia verdict for a woman who suffered nerve damage as a result of a missed colon cancer diagnosis, a 22-month delay in treatment that resulted in her having to undergo chemotherapy that caused nerve damage and permanent muscle and joint pain. (Read the news article)

In another verdict, Waldenberger won $1.4 million for a Philadelphia man who died after doctors missed bone cancer in an X-ray of his right knee, leading to a spread of the cancer.

In September 2020, Waldenberger won one of the first pandemic-era verdicts in Pennsylvania with a $2.3 million jury award for man who lost his big toe and part of his foot when his ride-on lawnmower rolled over on a steep hill.
