Demarco is the GOAT

John Demarco is an absolute gem of a lawyer. I had him on for two of my cases years ago and I cannot gas him up enough for how fantastic he was. I was a hell of a client and he stuck with me through it all with grace and clarity. He will fight for you. I am to this day (six years later) so grateful t...hat I had John Demarco representing me and helping me through the most challenging times of my life. If you want to feel cared for by a lawyer, choose Demarco.

Will go above and beyond for you

After being falsely accused by my narcissistic ex for abuse. I quickly scoured a legal defense team to help me take the best course of action. John Demarco is a great attorney who takes the time to hear your case and will give you honest feedback from the very beginning. John also shows a great deal ...of empathy for his clients and understands that they are people and not just dollar signs. He takes his time to direct and steer you with his expansive knowledge of the law and to guide you to the best path possible, but he never leads. He is a man of integrity, honesty and will tell you to your face what you need to hear and not stroke your ego and tell you what you want to hear. I genuinely appreciate John more than he probably knows and I now have my life back and can move on from my past. Thank you John and I wholeheartedly encourage anyone who is looking for a legal defense team to seek John and his associates.

"I had worked with John on numerous cases throughout my career as a prosecutor.

I always knew that if John was on the other side, he would spend countless hours defending his respective client, while maintaining a level of professionalism attorneys look up to."

Relationship: Opposing Counsel on matter

"I have had the opportunity to not only work with John, but also to prosecute cases which he was defending. I can state unequivocally that John approaches every single case as though it his freedom that is on the line. I know of no other attorney that researches cases and issues to the minute detail that John does. He flips over every rock and follows up on every possible lead to get his clients the results they deserve. In a time where legal research is an often forgotten attribute in an attorney, John shines in that regard. He also stays in contact with his clients, including in person meetings and follow up letters; but also is constantly in contact with opposing counsel in an effort to resolve matters. His professionalism and laid back demeanor are appreciated by everyone who he deals with."
