Cases We Handle
Our lawyers handle the following cases:
Personal Injury
- Assault injuries. These are injuries sustained as a result of criminal attacks.
- Medical malpractice. This is a legal cause of action that occurs when a medical or health care professional deviates from standards in their profession, thereby causing injury to a patient.
- Motor vehicle accidents. Negligent drivers and their insurers can be held accountable for the injuries you sustain due to their faulty actions on the road.
- Slip and fall. When property owners are negligent and cause injury to others, they may be held accountable under premises liability law.
- Product liability. This refers to a manufacturer or seller being held liable for placing a defective product into the hands of a consumer. The responsibility for a product defect that causes injury lies with all who are in the distribution chain.
Wrongful Death
Fatal injuries caused by the negligence or wrongful conduct of automobile operators, medical providers, or corporations can lead to lawsuits seeking compensation for surviving family members.
Civil Rights Litigation
This involves claims against law enforcement, governmental officials, correctional facilities, and other entities for violations of constitutional and/or civil rights.

Our firm takes pride in the many successful cases we have resolved, including those involving million-dollar and multi-million dollar awards. Every case is unique, and the results you may achieve will be based on the specific facts and circumstances of your situation.
