How We Transform Cases Into Causes

Our approach goes beyond traditional legal representation to create meaningful, lasting impact.

Thorough Investigation

We don’t just accept the surface story. Our team digs deep into every accident, examining systemic failures, corporate negligence, and root causes that others overlook. This exhaustive approach often reveals wrongdoing that quick-settlement firms miss.

Maximum Accountability

Negligent corporations and careless individuals must face the full consequences of their actions. We pursue accountability not just for compensation, but to create the pressure that forces systemic change and protects future victims.

Industry-Wide Impact

Your recovery is our priority, but your case can do more. We leverage every verdict and settlement to push for safety reforms, regulatory changes, and industry improvements that protect countless others from experiencing your tragedy.

How Can a Personal Injury Case Change the World?

In 2002, a young mother named Linda Kaiser walked in our door bearing the worst pain a parent could imagine. During nap time, her 12-month-old daughter, Cheyenne, managed to entrap herself in a cord hidden inside her window blinds. Tragically, Cheyenne died, but her death was not in vain.

Jim Onder took on the Kaisers’ case and won. It didn’t end there. One by one, other parents began to come forward to say that their children, too, were killed or permanently injured in window covering accidents. Every one of them fought the shame of thinking they were to blame, but they soon realized that their only mistake was in trusting a product they thought was safe. 

Like so many others who fall victim to corporate negligence and greed, they all thought that, if blinds were so unsafe, surely some regulatory agency would stop their sale. What they all learned is that, until we stand together and hold accountable those manufacturers, retailers, and others who cause harm, more families will be destroyed.

We are the change we are waiting for.

Linda and Matt Kaiser went on to start an organization called Parents for Window Covering Safety, which we proudly support. Together, we have forced window covering manufacturers to change the way they do business. Though there is still improvement to be made, window blinds are now safer than they have ever been, and countless lives have been saved.

OnderLaw holds individuals and corporations accountable when no one else does. Together, we are making a difference. Let us stand with you.
