Client Reviews
I was arrested and charged with drunk driving in New Rochelle after a traffic accident. Mr. McMillan worked tirelessly on my behalf and ultimately got the charges dismissed following a jury trial. I would recommend him to anyone. Bob, former client
My son was charged with drug sale following an incident which took place at school. Mr. McMillan was professional every step of the way and worked to ensure a good outcome. We are thankful for his efforts. Pam
I was convicted after jury trial in Supreme Court (for a crime I didn’t commit). Mr. McMillan worked tirelessly to make sure my conviction (and sentence) were overturned on appeal. I can’t thank him enough. George, former client
