Jeffrey Grubman, Esq. is a veteran ADR professional who has served as a mediator in approximately 2,000 cases in 31 states, the District of Columbia, and Puerto Rico in a wide variety of complex cases, including class actions and high impact, multi-party matters. Many of those mediations involved securities cases.

Before becoming a neutral, a significant portion of Mr. Grubman’s legal practice involved securities litigation and arbitration. He had a particular expertise in FINRA arbitration matters. He worked at Morgan, Lewis & Bockius for several years during which time he represented some of the largest brokerage firms in the world. Subsequently, he was a partner at two boutique South Florida law firms and represented claimants in FINRA matters. Mr. Grubman’s one and one-half decades of experience handling cases for and against brokerage firms, registered investment advisors, and other financial services companies uniquely qualifies him to evaluate securities disputes and to assist all parties in reaching a fair resolution. He understands the concerns and issues facing the investor, the broker, the brokerage firm, and their respective attorneys, and he interacts with all concerned in a respectful and professional manner.

In addition to serving as a mediator in securities arbitration matters involving the financial services industry, Mr. Grubman has litigated and mediated a wide array of securities litigation matters in court, including shareholder derivative actions, securities class actions, whistle blower actions involving the financial services industry and federal and state statutory securities claims against officers and directors of publicly traded and privately held corporations.

Mr. Grubman is certified by the Financial Industry Regulatory Authority (FINRA) and is a qualified arbitrator under Florida law. He is also certified by the Supreme Court of Florida as a certified Circuit and County Court mediator and by the Federal District Court for the Southern District of Florida.

I will definitely recommend your services should anyone be seeking a mediator.
