Multi-Generational History
SANFORD A. KASSEL, A Professional Law Corporation, is rooted in a deep, multi-generational history of legal excellence and community service. Our firm’s rich heritage (whose origin spans nearly 70 years) includes three generations of San Bernardino’s most prominent and well-respected trial lawyers, dating back to 1957, when Philip A. Kassel opened his first law office in San Bernardino, California. Sanford and Gavin are 2nd and 3rd generation of the Kassel/Katz Family of lawyers in the Inland Empire. The Kassel’s have maintained their offices in San Bernardino since 1957, with Sanford beginning his practice of law in 1981 and Gavin joining him in 2012.
Our esteemed trial lawyers have the expertise and resources to handle even the most complex Personal Injury, Medical Malpractice, Wrongful Death, and Employment Law cases Statewide in California. We represent victims of Serious Injury Accidents, Medical Malpractice and Wrongful Death caused by negligent, reckless, or unlawful conduct. We also advocate for individuals who have been Wrongfully Discharged, Discriminated Against, or Retaliated Against in the workplace. People across San Bernardino County, Riverside County, Los Angeles County, Orange County, San Diego County and surrounding Southern California areas have placed their trust in the dedicated attorneys of SANFORD A. KASSEL, A Professional Law Corporation.

with Gratitude And
In Memory Of Two Legal Giants

Our Firm’s heritage and legal legacy has forever been enriched through the contributions made by Attorney Philip A. Kassel, (Father to Sanford A. Kassel and Gregory H. Kassel, Grandfather to Gavin P. Kassel); and the Honorable Joseph A. Katz, Retired Superior Court Judge in the County of San Bernardino, (Father-in-Law to Sanford A. Kassel, and Maternal Grandfather to Gavin P. Kassel).
Sadly, in recent years, we have suffered the passing of both of these legal giants. Their knowledge of the law, and extraordinary skill sets within the practice of law live on each day through the Kassel’s; Sanford, Gavin, and Gregory — 3 very accomplished trial attorneys — each in their own right.
