He also has defended products liability cases on issues ranging from brain injuries and serious burn injuries to inhalation of asbestos, mold and other cancer-causing chemicals, loss of body parts and death, as well as injury claims based on helmet issues. Finally, he has defended and prosecuted civil cases on behalf of horse owners and trainers, including allegations of improper drug administration, personal injury to riders, breach of contract, and livestock injury claims.

He also was listed by San Diego Magazine in 2013–present as a “Top Lawyer” in the field of Real Estate/Land Use and has been listed as a “Recommended Insurance Attorney” by Best’s Review since 2003.

When he is not involved with his busy practice, Bill spends time with his wife and two young daughters on their small horse property in Poway, where he exercises and trains his own horses.
