Questions
Should I hire a lawyer after an accident?
Yes. Insurance companies have legal teams working to minimize payouts. An experienced attorney helps protect your rights and maximize compensation for medical bills, lost wages, and pain and suffering.
How are legal fees structured for personal injury cases?
We work on contingency fees, taking a percentage of your recovery. This percentage varies based on case complexity and resolution stage, with no upfront costs required.
What happens during the initial consultation?
We'll discuss your case details, assess legal options, and explain the process. There's no charge for initial phone calls or consultations, and we help determine if legal action is warranted.
How long does a personal injury case take?
Resolution time varies based on injury severity, recovery progress, and case complexity. We ensure all injuries are documented before pursuing settlement to maximize your compensation.
Can I get compensation for a concussion with negative CT scan?
Yes. Concussion injuries often don't show on CT scans. We use medical expert testimony and symptom documentation to prove brain injury claims against insurance companies.
