Halloween should be filled with costumes, candy, and fun memories. 🎃 A few simple precautions can help keep families safe while trick-or-treating:

✨ Be visible. Add reflective tape, glow sticks, or flashlights to costumes, especially after dark.

👻 Stay together. Young children should trick-or-treat with a responsible adult, and older kids should stay with their group.

🚗 Watch for traffic. Use sidewalks and crosswalks when available, and make eye contact with drivers before crossing.

🍬 Check the candy. Have an adult look through treats before kids dig in.

🦇 Choose costumes carefully. Make sure costumes and shoes fit properly and masks don’t interfere with vision.

Drivers, remember to slow down and stay especially alert in neighborhoods. Excited trick-or-treaters can be difficult to see and may enter the street unexpectedly.

At Nix & Diesselhorst, we hope you never need us. Part of standing with Oklahoma families is sharing simple safety reminders that can help prevent injuries before they happen.

Save or share these tips with another family before Halloween night!

Birth injury cases involve complex medical questions, and understanding exactly what happened during labor and delivery often requires more than reviewing medical records alone.

Medical experts can help evaluate the care provided, determine whether the standard of care was met, and explain how an injury may affect a child and family in the years ahead.

In our latest blog, we explain the important role medical experts play in investigating and building birth injury cases. Learn more: https://hubs.li/Q04zcrKr0

Making a Difference, One Oklahoma Family at a Time

For Kimberly and Chris Vorva, becoming part of the ND family meant more than having a legal team by their side.

After Kimberly was injured in a car accident, her spinal cord injury was not diagnosed and treated in a timely manner, ultimately resulting in paralysis. Her husband, Chris, remembers the Nix & Diesselhorst team’s commitment to doing everything they could to pursue justice for Kimberly while handling her case with integrity.

But one moment especially stayed with their family. On the anniversary of Kimberly’s car accident, ND attorney Andy Campbell delivered flowers.

That’s when the Vorvas knew that once you’re part of the ND family, you’re always part of our family.

It’s this same spirit of care and connection that inspires our commitment to making a difference for Oklahoma families, both through the work we do and in the community we call home.

At Nix & Diesselhorst, every case represents more than a result. It represents a person or family who trusted us during one of the most difficult times in their lives.

In this medical malpractice case, our attorneys secured a $7.5 million settlement involving a failure to diagnose and treat a stroke that resulted in permanent injury.

For our clients, pursuing a case can be about more than compensation. It can mean seeking answers, accountability, and the resources needed to move forward after a catastrophic injury.

We are honored to stand with our clients through every step of that process.

Nix & Diesselhorst. Standing With You.
