Louis received his Bachelor of Arts in Economics and Political Science from Binghamton University in 1990. He graduated in the top fifth of his class from Brooklyn Law School in 1993, and subsequently worked for nearly five years as a prosecutor in the Bronx County District Attorney's office.

While an Assistant District Attorney, he successfully prosecuted numerous high profile felony cases including homicides. In his last two years as a prosecutor, he further enhanced his trial skills as a senior trial attorney in the Felony Narcotics Bureau. “My experience as a prosecutor has subsequently proved invaluable in the civil sector. In addition to further developing my skills as a trial attorney the position also exposed me to the wonderful diversity that our city has to offer. The needs of crime victims were as personal and particularized as the cases themselves. Complex civil litigation similarly requires an attorney who can adapt to the individually tailored needs of the client.”

After leaving the District Attorney's Office in late 1997, Lou stepped seamlessly into a senior trial position and a subsequent partnership at the Wall Street defense litigation firm, Armienti & Brooks, P.C. While there, he successfully handled and tried numerous cases for the New York City Transit Authority, the New York City Housing Authority, and nearly a dozen private and public insurance carriers, representing building owners, corporations, small businesses, security firms and individual insureds. Lou has litigated and tried cases in all of the Supreme Courts in the New York Metropolitan area, and has successfully authored and argued his own appellate briefs on cases that he litigated in order to ensure that hard-fought victories at the Supreme Court level were upheld.

At Giordano, Glaws, Fenstermacher & Nash LLP, Lou's primary focus has been defending general liability matters and pharmaceutical malpractice actions for Walgreen's Pharmacies, in addition to handling various regulatory and administrative law matters. He has lectured to risk managers and hundreds of business owners on the legal issues confronting supermarket owners at various client seminars. In addition, Lou has been selected as a Super Lawyer, top-rated personal injury defense attorney every year since 2014.

Lou has sat as a pro bono arbitrator in Civil Court, Kings County in the Small Claims Court Division, is admitted to practice in the United States District Court for the Southern and Eastern Districts of New York, and is a licensed attorney in the State of New York. He is a member of the Brooklyn Bar Association and has worked with the New York City Bar Association in their efforts to assist small businesses in securing S.B.A. and F.E.M.A. funding in the wake of the World Trade Center tragedy.
