Jason’s practice focuses on the defense of a wide range of professional liability, commercial, casualty and white collar criminal matters, with a particular emphasis on legal malpractice and catastrophic injury disputes. Jason graduated magna cum laude from Boston University with a Bachelor's degree in Economics in 1996, and earned his Juris Doctorate degree from Georgetown University in 2000, where he was named to the Dean's List, and was the recipient of the Greenfield Trial Practice Award.

Upon graduation from Georgetown, Jason joined the Miami-Dade County State Attorney's Office in Miami, Florida, as an Assistant State Attorney. During Jason's tenure as a prosecutor, he tried approximately forty jury trials to verdict as lead counsel, and more than fifty bench trials, prosecuting such violent crimes as murder, attempted murder, manslaughter, kidnapping, sexual battery, and narcotics trafficking. Jason also argued on numerous occasions before the various Florida Appellate Courts and was specially appointed by Executive Order of the Governor to represent the state of Florida in conflict situations.

Jason has been recognized as an Ohio Super Lawyer by Law and Politics Magazine, and repeatedly has been identified in Best Lawyers in America for Legal Malpractice and Professional Liability Law. In 2016, Jason was recognized as one of three professional liability defense lawyers for the State of Ohio by Super Lawyers Annual Directory, Business Edition. Jason has tried jury trials throughout the states of Ohio and Florida, and has argued before the majority of their appellate courts. Jason also has authored amicus curiae briefs before state supreme courts on behalf of interested parties in professional liability matters.

Jason is truly honored to serve as outside General Counsel to some of the finest attorneys and law firms in the region, providing integrated and cost-effective solutions to the full spectrum of operational, transactional, and litigation challenges facing legal services providers during all phases of formation, practice and evolution. In so doing, Jason is able to provide reasoned guidance to attorneys on matters including legal malpractice, bar grievance and fee dispute defense, formation, operations, dissolution, risk management, human resources and employment practices, and succession planning.

Jason is admitted to practice before the Courts of the States of Ohio and Florida, the United States District Court for the Northern and Southern Districts of Ohio and Indiana, the Eastern District of Michigan, and the Southern District of Florida, the United States Court of Appeals for the Sixth and Ninth Circuit, and the United States Supreme Court.
