    Attorney Profile

    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.

    As an undergraduate, Mr. Mercaldo attended the University of Arizona and received a Bachelor of Science in 1967. He then went on to attend what was then known as the University of Arizona James E. Rogers College of Law and was awarded his Juris Doctor in 1971. 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. This experience has served him in good stead in his plaintiff's practice as it allows him to anticipate the strategies that insurers are likely to employ.
