Si Aydiner is a solo practitioner in Mineola and Manhattan focusing on the defense of attorney discipline matters. He was previously a staff attorney with the Attorney Grievance Committee for the First Judicial Department. With the Committee, Si led investigations and prosecutions into hundreds of matters including money laundering, judgment and tax evasion, conflicts of interest, escrow misconduct, neglect, and personal misconduct. Among his notable cases, Si co-led the prosecution into the joint 60 Minutes-Global Witness exposé—viewed by over 9 million people—into New York lawyers aiding offshore money laundering. Before joining the Attorney Grievance Committee, Si was spent 6 years with Queens County’s largest plaintiff’s personal injury firm where he rose to the level of general counsel. While there, he handled all aspects of the firm’s personal injury case load including trials and appeals. As general counsel he represented the firm in all matters including the successful defense and dismissal of multiple mortgage fraud cases directed against the firm from the multi-million dollar theft of its former associate on a theory that banks, as assignees, lacked standing to pursue tort claims. His highlight personal injury case resulted in the Second Department’s 2015 reversal of its long-standing prohibition of driver-passenger conflict waivers, Sacco & Fillas, LLP v. David Broderick, PC. Before joining Queens County’s largest firm, Si clerked for the Honorable James E. Gates in the United States District Court for the Eastern District of North Carolina in Raleigh.
