Through conscious effort to focus on the plight of those who have been injured through medical negligence and malpractice, Anthony O'Hanlon has become a litigator of note in these areas. Raised in a small town, he has carried his small town values in standing for those suffering from medical malpractice and negligence as well as injured in car wrecks and truck accidents.
