A Car Accident Is Never an Accident
A personal-injury attorney explains a deliberate office rule: they don't represent people injured in "accidents" — because a liability claim requires that someone else was at fault, and nearly every wreck traces back to a negligent choice, not bad luck. A pointed look at why that one word matters to your claim.

Most Car Wrecks are Intentional
A car wreck's outcome may be unintended — but the choices behind it rarely are. Using two vivid examples (a driver speeding to beat a light, another changing lanes without looking), this piece argues that most crashes flow from intentional conduct, and that a driver's intent to injure is irrelevant when their intended actions cause the harm.

What Happens When a Spinal Cord Injury Prevents You from Returning to Work?
Spinal cord injuries range from temporary loss of sensation to permanent paralysis—and when they keep you from returning to work, the financial impact can last a lifetime. Insurance companies tend to focus on the wages you missed during recovery, but that's only part of the story. Lost earning capacity—the income you'll lose in the years ahead—is often where the real stakes lie, and it's exactly what insurers fight hardest to minimize. Learn why early lump-sum offers rarely cover the true lifetime cost of a spinal cord injury, and how a long-term legal strategy protects your future.

What Our Clients Say
“Several months ago we requested the services of Mark Van Paasschen of the Bison Law Firm in a civil matter involving a young close relative. This is the second time we worked with Mark. Mark and his assistant, Karen, were extremely helpful in bringing the case to a very successful resolution. Mark's assistant, Karen, was able to research and develop some enlightening background material with respect to the case. The evidence revealed the person filing a civil complaint, in this matter, was basically a "serial" complainant with respect to similar matters involving multiple neighbors . The informatiion developed by Karen and additional evidence provided by the close relative was presented during a hearing which resulted in a quick resolution of the matter. Mark was very assuring and worked well with our younger close relative to bring this matter to a prompt and satisfactory conclusion. We can strongly reccomend Mark and the Bison Law Firm for legal assistance without hesitation.”
