Our firm is highly regarded for its extensive experience in all types of personal injury cases, including dozens of cases on behalf of people who developed primary pulmonary hypertension (PPH) after using the diet drug Fen-Phen. This disease is also called Pulmonary Arterial Hypertension (PAH).

A History of Firsts

Hersh & Hersh is a pioneer in the field of defective drug litigation. Our attorney experts in defective drugs know how to take on the giant pharmaceutical companies and win. Our groundbreaking work includes the:

• First case linking the defective diet drug Fen-Phen to PPH
• First Fen-Phen case filed and settled
• First breast implant case to link silicone to physical injuries
• First DES lawsuit — a $41 million jury verdict for a group of 11 injured women
• First Zyprexa lawsuit
• First mass torts claim

We have extensive trial experience in large, groundbreaking cases. Our partners have almost 100 combined years of diverse trial experience in major litigation, both on an individual level and in class action and multi-district litigation that involves large numbers of clients, each of whom receives individual attention.

A Tradition of Service

Our firm was founded in 1970 by attorney Leroy Hersh and his daughter Nancy. Although we are recognized as a legal powerhouse, we remain, at heart, a family law firm whose lawyers and staff care deeply about every case and every client. A firm partner will lead your case and bring in other firm members as needed. You will deal with an attorney, not a paralegal or legal assistant. If you cannot reach your attorney immediately, your call will be returned the same day.

As part of our commitment to protecting individuals, Hersh & Hersh has a long history of supporting groups that provide patient advocacy, educational and support services. Our generosity has been recognized by groups including the Pulmonary Hypertension Association, DES Action and Disability Rights Advocates.

A Record of Success

At Hersh & Hersh, we succeed when you succeed. We are only paid if we are successful in your lawsuit. If you took Fen-Phen and later developed PPH, please contact our law firm today to arrange a free initial consultation.

From our offices in San Francisco, California, the lawyers of Hersh & Hersh represent PPH victims throughout the nation.
