Fighting for Phoenix Accident Victims
When you have been hurt in a car accident, trucking crash, or slip and fall in Phoenix or anywhere in Arizona, you deserve an attorney who knows Arizona law — and who will fight for every dollar you are owed.
Arielle K. Allen is licensed in Arizona and brings the same tenacity to Phoenix cases that has earned her recognition as one of the National Trial Lawyers Top 40 Under 40. She is also a PhD candidate in Experimental Psychology with a specialty in traumatic brain injuries — giving her clients an edge in TBI cases that most attorneys simply cannot match.
Arizona follows a pure comparative fault rule, which means insurance companies will try to pin as much blame on you as possible to reduce their payout. Arielle knows these tactics and knows how to counter them. Consultations are always free, and she never collects a fee unless she wins your case.
What We Handle
Phoenix Practice Areas
Car & Auto Accidents
Arizona is a fault state — the at-fault driver's insurance is responsible. Arielle investigates liability, preserves evidence, and fights for full compensation including medical bills, lost wages, and pain and suffering.
Trucking Accidents
Commercial trucking cases in Arizona involve federal FMCSR regulations and multiple liable parties. Arielle knows how to read driver logs, black box data, and inspection records to build a winning case.
Traumatic Brain Injuries
TBI cases are often invisible to insurers and juries. As a published TBI researcher and PhD candidate in Experimental Psychology, Arielle brings unmatched depth to every brain injury claim in Arizona.
Premises Liability
Property owners in Arizona must maintain safe conditions. When they fail — wet floors, inadequate lighting, negligent security — and someone is hurt, they can be held accountable.
Wrongful Death
When negligence takes a life, Arizona families deserve justice. Arielle handles wrongful death claims with the sensitivity and tenacity these cases demand, pursuing full compensation for surviving families.
Pro Bono Representation
Arielle accepts a limited number of pro bono cases each year for Arizona individuals facing serious legal challenges who cannot afford an attorney. Reach out — she will listen.
