Home / Medical Malpractice / Misdiagnosis or Delayed Diagnosis Causing Wrongful Death
Patients seek medical care with the expectation that doctors will listen, investigate, and act promptly. But when symptoms are ignored, conditions are misdiagnosed, or diagnoses are delayed, the consequences can be fatal.
According to a 2023 study in BMJ Quality & Safety, diagnostic errors contribute to nearly 800,000 deaths and disabilities every year in the United States. These are not rare errors— they are a leading cause of wrongful death in hospitals and clinics.
For Arizona families, losing a loved one to misdiagnosis is especially painful because the death was preventable.

These statistics underscore the danger of doctors ignoring symptoms or failing to act quickly.
Under A.R.S. § 12-611 to 12-613, Arizona families can file wrongful death lawsuits when negligence causes a preventable death.

Brian Snyder, attorney, was the only one who took my case more than five years ago. I could not find an attorney in the state of Texas. I spoke to many of the attorneys and law firms throughout Texas. I told them my symptoms were swollen lymph nodes, early signs of a recurrent hernia on my left groin, and I was always in pain. No attorney wanted to help me throughout the state of Texas. Brian Snyder, attorney, took my case without any hesitation. He knew right away what I was going through. Cause of Brian Snyder, I was able to get a settlement payment for an XL mesh plug and onlay. I truly recommend Brian Snyder if any person is experiencing a recurrent hernia or mesh problems. I truly recommend him as an attorney to get you results. I consider Brian Snyder very sneaky, intelligent, with a lot of experience, and a view of common sense. Brian Snyder was very patience and understanding with my case. Brian Snyder is a very bright attorney. I wholeheartedly recommend that you give him a call. I am happy with the settlement and on my way to view and relax by the ocean. Thank you, Brian Snyder, for your help.Posted on Google![]()

One can't begin to convey the immense gratitude we have for David Wenner. We were fortunate to have his highly skilled counsel for our brother, Richard who was involved in a life changing accident through no fault of his own. The enormity of his immediate medical needs and placement in ICU for several months was more complicated with us living out of state. David and his paralegal Jen showed their humanity and compassion in helping us to navigate the insurance and legal issues while staying abreast of Richard's ever-changing condition. They allowed us to concentrate on his care and recovery which was a true blessing. Richard continues to make progress, and he is indebted to David for helping to ensure his care for the future. Thank you, David & Jen !Posted on Google![]()
