What Weiss & Paarz, PC does

Weiss & Paarz, P.C. is a plaintiff-side law firm focused exclusively on medical malpractice cases, serving victims and families in Pennsylvania and New Jersey. The firm handles catastrophic injury and wrongful death claims arising from birth injuries (cerebral palsy, Erb's palsy, kernicterus, Group B Strep/meningitis), brain injuries (anesthesia errors, airway management, hydrocephalus, stroke misdiagnosis), cancer misdiagnosis (breast, cervical, colon, prostate, skin), hospital and emergency room malpractice (sepsis, heart attack, cauda equina), and prenatal misdiagnosis. Six offices span the Philadelphia/Bala Cynwyd and New Jersey (Northfield, Iselin, Cherry Hill, Toms River) markets, with intake via phone (1-800-952-8444), website, SMS, email, and chat.

The firm operates on a contingency fee basis under a 'No Win, No Fee' arrangement: clients pay no legal fees or costs unless the firm recovers compensation, at which point a percentage covers legal fees. Its core capability is the integration of legal and medical expertise—two on-staff physicians (Dr. Brian Timms, DO in internal medicine and Dr. Diane Timms, DO, double-board-certified in OB/GYN and Maternal-Fetal Medicine) plus multiple registered nurses support case screening, standards-of-care analysis, and litigation. Several attorneys previously defended medical malpractice claims before joining the plaintiff side, providing defense-side insight.

The firm was founded in 2003 by Michael L. Weiss and Robert E. Paarz, both admitted to the bar since the early 1980s and 1990s respectively, and reports over $400 million in cumulative client recoveries across more than 175 years of combined attorney experience. Recognition includes consecutive Super Lawyers listings since 2005, Best Lawyers in America, Martindale Hubbell AV rating, American College of Trial Lawyers fellowship (Paarz), and National Trial Lawyers Top 100 (Weiss). The firm is a privately held professional corporation with no external investment.
