If you’ve been hurt due to someone else’s negligence, you deserve an attorney who will fight for your rights and hold insurance companies accountable. We handle a wide range of personal injury cases, including:

Car 
Accidents

A car accident can leave you facing medical bills, lost wages, and ongoing pain. Whether it was caused by a distracted driver, speeding, or reckless behavior, our Walnut Creek car accident lawyers fight to recover the maximum compensation you deserve.
Truck 
Accidents

Crashes involving 18-wheelers and commercial trucks often result in severe injuries due to their size and weight. Our Northern California truck accident attorneys know how to investigate trucking company negligence, driver fatigue, and safety violations to hold the right parties accountable.
Motorcycle 
Accidents

Motorcyclists are especially vulnerable on the road, often suffering life-changing injuries in collisions with larger vehicles. Our motorcycle accident lawyers fight for the rights of injured riders and work to secure full compensation for medical expenses, lost income, and long-term recovery.
Slip

A slip and fall can lead to serious injuries, from fractures to traumatic brain injuries. Whether it happens on a wet floor or uneven pavement, property owners have a legal duty to maintain safe premises. When they fail, our slip and fall lawyers can hold them accountable.
Stairs/
