Daniel McGuinness moved to New York City in 2003 to attend New York University School of Law and fell in love with NYC, living here ever since.  Mr. McGuinness worked in private practice on civil matters following admission to the bar, until working with Adam Perlmutter in United States v. Gioeli.  Mr. McGuinness second-chaired the historic Gioeli trial that led to the acuital of Mr. Gioeli on six counts of murder, including the charged murder of a police officer in an organized crime case in over 100 years.  

In 2015, Mr. McGuinness and Mr. Perlmutter founded Perlmutter & McGuinness, PC, a law firm dedicated to aggressive criminal defense and civil rights litigation.  The firm has generated significant media coverage for its high-profile criminal cases as well as the notable civil rights victories it has acheived.
