Background on John J. Gebbia

John J. Gebbia brings decades of leadership experience and expertise in the financial services industry to his new role and will be responsible for leading Siebert in its next phase of innovation and growth. Mr. Gebbia has been a member of Siebert’s Board of Directors since 2020 and served as a special advisor to Siebert’s Board of Directors from 2017 - 2020. After the purchase of Siebert by the Gebbia Family in 2016, Mr. Gebbia was instrumental in growing Siebert’s annual revenue from $10 million to over $67 million in 2021, the acquisition of the self-clearing brokerage StockCross Financial Services, Inc., and diversifying and expanding Siebert’s business lines.

Born in Sicily, Italy, and immigrating with his family through Ellis Island, NY, the beginnings of his business success started on the floor of the New York Stock Exchange. Mr. Gebbia has completed dozens of transactions over his career and held executive roles at companies such as Merrill Lynch; Walston & Company; and Jesup, Josephthal & Co. Mr. Gebbia’s most notable transaction was the acquisition of Kennedy Cabot & Co. for approximately $7 million, which he grew into the leading independent discount stockbroker in the U.S., and ultimately sold to Toronto-Dominion Bank 7 years later for approximately $155 million.

Mr. Gebbia and the Gebbia Family have also flourished in other business ventures in real estate, entertainment and sports. In addition to his business accomplishments, Mr. Gebbia has been married to Gloria E. Gebbia for over 60 years, and together they have 10 grandchildren and have raised three successful sons: John, Richard and David, who currently lead Siebert’s management team.
