Victims of serious and catastrophic injuries in accidents caused by negligence have one thing in common. They need the help of a skilled, compassionate personal injury attorney with a reputation for results. The Mercaldo Law Firm takes pride in its reputation of always being prepared, with legal knowledge and medical information to successfully prosecute our clients' claims through a jury trial.
A doctor commits medical malpractice by negligently providing medical services when that negligence causes or contributes to injuring the patient. The injured party must first prove that the health care provider fell below the standard of care for similar health care providers in Arizona. That means the health care provider failed to act as a reasonable and prudent health care provider in Arizona would under similar circumstances.
If you believe that an error by a doctor, nurse or midwife caused serious or catastrophic injury to your child, you have legal rights that must be protected. The aftermath of a birth injury can be devastating - for the newborn, the family and its loved ones. The cost of long-term care for a child with Erb's palsy or cerebral palsy has been estimated at more than a million dollars over a lifetime.

Words cannot ever fully express how grateful we are to have had the team at Mercaldo Law Firm on our side during a very difficult time for our family. Halley & Ron were genuinely compassionate, responsive, honest, and very professional during their fight for my mother’s newly disabled life ahead. It took a while to get to our ending result due to the delay of the pandemic- however, the team at Mercaldo Law Firm never left us in the dark and stayed communicated throughout. From the very beginning, we immediately knew we were in good hands and they reassured us with that feeling throughout the

Can't say enough good things about Ron and his team. From start to finish, their professionalism was matched by their obvious care and concern for us personally. Always quick to respond, kept us in the loop and led us to a great result. Highly recommended.

I was 19 years old when I suffered a life-changing injury. At such a young age, I had no idea how to handle the gravity of the physical injuries and the medical expenses I was facing. Carlo, Ron, and the entire Mercaldo Law Firm held me in the palm of their hand as they carefully and thoughtfully explained the legal process at hand. From the very first meeting, they treated me with the utmost respect and kindness. Carlo worked tirelessly to ensure that I was represented with conviction and integrity. He fought for what we believed was right and just. Carlo and the Mercaldo Law Firm are trusted

I was very happy through out the process of my litigation, from his office staff, paralegals, to Marco himself. Marco was a step ahead of them and explained things to my understanding through the whole process. Excellent Law Firm.

From the very first meeting Marco treated us with the upmost respect and kindness. He worked tirelessly to represent our family and story with conviction and integrity. His skillset is unmatched and the way he works with his clients is unprecedented in medical malpractice. Marco invested his expertise and substantial network of medical experts in our case to create a platform for us to tell our story. After 15 years of service in the military, only a man of Marco’s caliber could have represented my husband, his character and his achievements the way Marco has done. He has become a trusted advisor

My family and I cannot say enough good things about the Mercaldo Law Firm and Marco Mercaldo in particular. As a teenager who was injured in a car accident, my life was definitely turned upside down. Marco proved to be invaluable in his steadfast and genuine concern that I receive the best possible medical care and legal representation. Every step of the way, he made sure I understood what was happening and the complex legal world that my family and I found ourselves in. Marco won my insurance claims but, more importantly, he was caring and compassionate, as was everyone in the firm. A big thank

My brother in law researched law firms for me (I was unable to due to my accident) and he was impressed with the Mercaldo Law Firm. Right from the start Marco was kind, knowledgeable and very easy to work with. Both Marco and Sandi were always available for phone calls and emails. They worked hard to help get me through a difficult time. I would highly recommend anyone needing a personal injury lawyer to use the Mercaldo Law Firm.

I was sure I was in good hands the moment I stepped foot into Mercaldo Lawfirm. With tremendous compassion, dedication, and hard work, Carlo Mercaldo made sure I was compensated for the devistating injuries I had incurred. Now that my case is resolved I can say that I am pleased with the result, and I could have never done it without the help of Carlo and his colleagues. This team went above and beyond for me; and for that, I am truly grateful.
