About Carter Mario

Carter Mario has been practicing law in Connecticut for over 30 years. He attended college at the University of North Carolina, Chapel Hill on a full wrestling scholarship and from there went to law school at Stetson University College of Law in St. Pete, Florida. He chose to return to his hometown of Milford, Connecticut to start his practice.

As Founder and President of Carter Mario Law Firm, Carter has spearheaded tremendous growth. What started in a one-room office has grown into Connecticut’s largest personal injury law firm with six, fully staffed offices across the state. “We’re big enough to go against any insurance company but small enough to care about our clients,” said Carter. “Our growth has been possible because of the excellence, care, and compassion with which we have served thousands of clients. Everything we do is about putting clients first,” Carter said. “That is the foundation of the firm. I love when the representation ends with a fully satisfied client that we have helped to make a positive difference in their life.”

“I have built my career on helping injured individuals to rebuild their lives. That’s what brought me to focus my practice on personal injury. No two personal injury clients or cases are exactly the same. Each one of us has a different story to tell. That’s why I create a personalized, comprehensive strategy in order to secure the best possible outcome for each client after they have been injured due to the negligence of another person. I strive to ensure that our clients get what they truly deserve.”

Throughout his legal career, Carter has received numerous awards for his legal abilities and impressive track record, including being featured in books and numerous publications that highlight top businesses focusing on culture and customer experience. His perfect 10.0 Avvo rating speaks volumes about his skills, passion, and dedication to his clients. Carter holds an AV preeminent rating through Martindale-Hubbell. As such, he is part of an elite group of attorneys who have been highly rated by their peers as having very high ethical standards and an A grade of 4.5 or higher. He is also passionate about helping those organizations that need his help through the firm’s CarterCares outreach program. Attorney Carter Mario is licensed to practice in Connecticut and the U.S. District Court of Connecticut.

Carter is married to his college sweetheart, and they have 3 children and 2 grandchildren. Two of his kids, Alex and Luke, work with him at the firm as attorneys. When he is not working, you can find him hard at work on his tractor or excavator digging holes and making trails on his property in Vermont. He is an avid motorcycle rider as well as a top-notch peloton rider and cyclist. Carter believes staying in shape gives him the mental toughness, energy, and well-being to keep him on top of his game and be the best version of himself so that he can be the best advocate for those that depend on him.
