For over three decades, Bill has repeatedly produced favorable results in contentious trial work and litigation. He has prosecuted landmark condemnation litigation against state agencies for their failure to properly supervise and implement an effective cleanup plan at a CERCLA site, and prosecuted the contaminator of the site without becoming involved in the then-pending CERCLA litigation. Other real estate issues he handles include eminent domain, inverse condemnation, flooding, landslides, earth movement, environmental issues, boundary disputes, partition issues, lateral/subjacent support issues, and construction defect. 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.

Bill has held the highest possible AV Preeminent® rating by Martindale’s nationwide attorney peer review rating since 1976. He also was listed by San Diego Magazine in 2013–2017 as a “Top Lawyer” in the field of Business Law 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.
