Cablevision Systems said Monday that it has named Gregg Seibert vice chairman. In addition to the new position, Seibert will continue as chief financial officer, reporting to Cablevision CEO James Dolan.
As vice chairman, Seibert, 57, will collaborate with Dolan and the senior management team on the formulation and implementation of Cablevision’s overall strategy, helping to position the company for long-term success in an increasingly competitive marketplace. He will work closely with Hank Ratner who also serves as a vice chairman of Cablevision.
“Since joining Cablevision four years ago, Gregg has played an instrumental role in helping to guide the company’s transformation through a number of strategic initiatives, including the spin-offs of The Madison Square Garden Company and AMC Networks,” Dolan said in a statement. “He has successfully addressed a multitude of challenges and opportunities, consistently focusing on identifying ways to build value for our shareholders. I look forward to Gregg’s ongoing contributions in this important new role.”
Seibert will continue to serve as Cablevision’s CFO, overseeing the company’s financial and accounting matters, as well as its investor relations, treasury, taxation, risk management, and business development activities.
Before joining Cablevision in 2009, Seibert spent two decades at Merrill Lynch working on various financial and strategic transactions for companies across a number of industries. His work included banking activities for some of today’s top media companies such as Cablevision, Comcast, Liberty Media, News Corporation, and many others. Seibert’s last position prior to joining Cablevision was senior vice president and vice chairman of Merrill Lynch, which he joined in 1989 as a managing director and head of the Global Media Group.
Seibert received his MBA from the Wharton School of the University of Pennsylvania.
