Warren Zimmerman has practiced law for 39 years, the last 35 in Florida. A native of Cleveland, Ohio, Warren holds a Bachelor of Arts degree in economics from Yale University with honors and earned his law degree at the University of Michigan with high honors in 1979.
Warren began his legal career in Chicago, where he served for several years with the State’s Attorney’s Office for Cook County, Illinois, prosecuting criminal cases at trial and on appeal. In 1983 he realized his goal of becoming a federal prosecutor when he was hired as an Assistant United States Attorney for the Middle District of Florida.
Working in the Criminal Division of the United States Attorney’s Office from late 1983 until March 1987, Warren tried 13 felony jury cases to verdict. His cases related to bank and mortgage fraud, official corruption, drug smuggling, immigration, human trafficking and counterfeiting, among other facets of federal criminal law. He then served in the Civil Division for the next 21 years, the last 14 as Division Chief. In that capacity, Warren supervised virtually all civil litigation filed by or against the United States and its agencies in an area encompassing Tampa, St. Petersburg, Jacksonville, Orlando, Ocala, Lakeland, Sarasota, Fort Myers, Naples and most points in between. Warren handled many sophisticated cases involving personal injury, medical malpractice, wrongful death, employment discrimination, contract and suretyship, bankruptcy, foreclosure, administrative law, drug diversion, and health care and other program fraud.
Warren has been in private practice since retiring from the federal service in August 2008. Besides working as a mediator in the state and federal courts of central Florida, he has worked on many cases involving plaintiff’s personal injury, contracts, real estate and mortgage lending disputes, and insurance coverage. Since 2016, he has focused increasingly on federal criminal defense.
Warren is a member of the Illinois and Florida Bars and is admitted to practice before the United District Courts for the Middle District of Florida and Northern District of Illinois.
In his spare time, Warren enjoys baseball. He was a member of Tedd Webb’s trivia panel on WFLA Radio’s “The Sports Huddle” in the late 1980s.
