Our Mission

“We believe California consumers have the right to transparency and safety. Businesses that violate that right will be held accountable.”

Understanding Proposition 65

Also known as the Safe Drinking Water and Toxic Enforcement Act of 1986, Prop 65 requires companies doing business in California to warn consumers about exposure to known carcinogens and reproductive toxins.

Sentinel Law APC ensures compliance by filing 60-Day Notices of Violation, litigating in the California Superior Court system, and seeking maximum statutory penalties when companies fail to act responsibly.

We file 60-Day Notices of Violation – and are fully prepared to litigate in the California Superior Court system.

“We build strong, science-backed cases that stand up in court.”

Environmental Litigation

Beyond Proposition 65, we take on broader environmental cases involving unsafe consumer products, toxic chemical releases, and public exposure to hazardous substances.

We fight to hold corporations accountable for environmental harm.
