Great Lawyer and Person

Greg cares about the facts of the cases. As an activist the police in Nassau County have made a target of me. TWICE I have been the victim and had to fight TWO bad cases we won at one trial and now another is being dismissed. Greg handled my warrant when I missed a date while on the West Coast and ha...s been fighting for me while out here I have not had to return. He always calls back and goes out of his way for his clients. Grizopolous & Portz puts a huge dent in the pathetic DAs conviction rate where they will carry on cases knowing the person is innocent. Pricing is very reasonable and well earned. I can't recommend Greg enough! A lawyer that actually listens and looks at the case with diligence.

Charged with 2 felonies

I just wanted to take the time and speak on my experience with Greg Grizopoulos. I was extremely impressed by the way greg and his team handled my case (s). I have used greg in the past for a Aggrivated DWI, which of course got dismissed after a couple months. My most recent and definitely most sever...e case which included 2 felonies and a misdemeanor I knew without a doubt I needed Greg to represent me. From day 1 greg always kept me informed on what was going on, what I needed to do, and ALWAYS told me what was the best option for us to take. Anytime I called, Greg was always there! Weekdays, weekends, late in the evening, it didn't matter he always answered his phone, and if he didn't he always got back to me within the half hour. He definitely had me remain calm throughout the process. The outcome was more then expected, 2 felonies dropped to a violation--- can't beat that!! Anyways greg is a amazing lawyer and I highly recommend greg for any legal issues you might encounter. You are not just another client, he goes above and beyond for any legal issue big or small!

DWI case - excellent attorney

I cannot express my gratitude to Greg and his wonderful team for his outstanding work and support on my case. My charge was a DWI and I honestly did not think I would see a good outcome. However, due to Mr. Grizopoulis who always showed up to every hearing prepared and confident my outcome was more ...than I hoped for. During my trial and watching him in the courtroom...he is truly an amazing lawyer. This is the attorney you want sitting beside you. I would highly recommend him.

This from a juror ...

I was just on a jury where Greg Grizopoulos was the defense attorney, and I was so impressed with his skills and his presence in general, that I looked him up so I could write a reference. If I ever need a defense attorney, I would, without doubt, give him a shout.

  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
