    “We wanted to take a moment to thank for all the hard work and commitment you and your paralegals put into our legal case. You have been patient, understanding and supportive over these past few years, which in turn made this difficult situation more bearable. Thanks again for everything you did and it was a pleasure meeting you. Thank you!”

    “Months had gone by without any help so it was time for a change. I came across John Mattiacci Attorney in civil suits. I explained to John in detail about the person who ran a stop sign, and he always kept eye contact except to write down information. John was the attorney I needed. I fired the firm who I had who did nothing. John went to work and I mean he went to work… The amount of money is between John, and I, it was five times what I thought it would be. John is the nicest attorney until his clients are pushed. I have seen this in person in action, need I say more.”

    - Mark

    “John is an excellent lawyer. I hired John after being hit by a drunk driver. In addition to getting me a fair settlement, John was knowledgeable, patient, and thorough. He kept me informed every step of the way and his friendly, easy going manner made it easier for me to recall the disturbing details of the accident and the difficult months following it. I would recommend John to anyone who needs a good lawyer.”

Our Approach

We don’t settle for anything less than the best

Most cases don’t make it to trial, but we prepare for it regardless. Insurance companies use many tactics in an attempt to cheat you out of the settlement you deserve, and sometimes, escalating to trial is necessary.

Meet Managing Attorney John Mattiacci

For more than 16 years, I have represented clients who were paralyzed, brain-damaged, permanently injured, or killed. I pride myself and am honored by the many opportunities I have had to help families pick up the broken pieces and put their lives back together after devastating injuries or death.

At the heart of my practice is service. When you work with me, you are family, and I fight for you like you are one of my own. Not all law firms offer the dedicated attention that myself and my associates can, and we wouldn’t have it any other way.
