The founder of The Mercaldo Law Firm located in Tucson, Arizona, Ronald D. Mercaldo focuses his practice exclusively on personal injury and wrongful death litigation. He provides representation to clients in the state and across the Southwest who have been harmed by the negligence of others in cases involving medical malpractice, commercial vehicle accidents and similar matters.

After graduation, Mr. Mercaldo spent several years at a civil litigation firm that provided defense counsel to insurance companies in personal injury lawsuits until founding The Mercaldo Law Firm in 1978.
