Let us focus on your legal fight while you focus on recovering from your injuries.

Auto Accident

We will fight to limit how far car accidents set you back.

Car accidents don't just happen be chance. They happen because someone did something wrong. A number of factors contribute to the risk of collision, including vehicle design, speed of operation, road design, road environment, and driver skill, impairment due to alcohol or drugs, and behavior, notably speeding and street racing. Worldwide, motor vehicle collisions lead to death and disability as well as financial costs to both society and the individuals involved. Bodily injuries will impact all aspects of your life, sometimes throwing your life into turmoil.

When you are injured in a car accident, we will take care of the legal hurdles towards a financial recovery so you can focus on getting better.

Medical Malpractice

We can help you hold negligent health care providers responsible for the injuries they cause.

Medical malpractice is an epidemic in the U.S. Preventable medical errors kill more than 400,000 people per year. That means, every day, 1,100 people have their lives cut short by medical malpractice. Medical malpractice cases rarely, if ever, resolve without hiring a lawyer. Our lawyers will fight to eliminate poor quality care, obtain fair compensation for our clients, and impose justice in a manner that makes future occurrences less likely.

We know most health care providers are good people and want to help their patients, but the financial pressures caused by decreasing health insurance reimbursement rates and increasing costs lead to mistakes. When health care providers make mistakes, your life and livelihood are at risk. Therefore, the civil justice system provides a path for injury victims to be compensated when their injuries are caused by negligence. It's not an easy path because health care providers do not like to admit they were negligent and the costs to pursue these cases are ridiculously high.

Medical malpractice cases are complex with several nuances. It is essential to get advice and representation from an experienced team, like us. If you believe that you or a loved one has been injured by a health care provider’s negligence, then you need to call the medical malpractice lawyers at Gage Mathers.

Trucking Accident

We will fight to limit how far truck accidents set you back.

Our truck accident lawyers have been involved in some of the most catastrophic truck crashed in the Southwest. Truck accidents can be the most catastrophic crashes on the road. These massive vehicles are difficult to stop quickly, cannot safely make evasive maneuvers, and outweigh your car or SUV by several tons.

There are many different types of trucks on the road, including:
18 Wheelers, and
Tractor Trailers.

These “road hogs” cause all kinds of crashes, including running victims off the road, underride collisions, head-on collisions, rollovers, rear-end collisions, and side collisions. Theses crashes are usually caused by the driver’s reckless behavior. A variety of causes are behind this reckless behavior, including:
Reckless driving,
Defective equipment or equipment brake failure,
Overloaded trucks,
Inexperienced drivers,
Weather conditions,
Road design,
Impaired visibility,
Driver fatigue,
Driving under the influence of drugs and alcohol, and
Distracted driving.

We have vast experience in bringing big-rig drivers and owners to justice when they cause a crash. These cases require an experienced truck accident lawyer. The best results start when we are able to begin our investigation as soon as possible. These cases have unique issues like “disappearing evidence” and a culprit that leaves town because they are simply passing through the state. That’s why you need to call Gage Mathers now – before it’s too late.

Wrongful Death

Gage Mathers’s wrongful death lawyers understand the deep sadness and sorrow that comes with losing a loved one.

The pain can be amplified by the anger of knowing how your loved one died. It might have been in a tragic accident or at the hands of someone they trusted, like their health care provider.

Our mission is to help families find out why their loved one died and determine if it was a wrongful death. We will work to hold the responsible person accountable. In the process, we provide families with information and support–we take the term “counselors at law” seriously and believe our clients deserve compassionate and personalized representation.

“Wrongful death” is the term used to describe the tragedy that occurs when a death is caused by someone else’s negligence. It is often unexpected and devastating. It can have dire consequences for your family. The emotional toll is much harder to bear when someone else is to blame for your loss. You also might be struggling with fear because of lost economic support from your loved one.

A wrongful death case might help with all of these issues. Call the experienced wrongful death lawyers at Gage Mathers to see if they can help.
