Ladenburg Thalmann Financial Services has made a flurry of appointments, including that of Adam Malamed as its chief operating officer. The rest of the appointments are for executive-level spots at its broker-dealer, Ladenburg Thalmann & Co.

As part of the reorganization, David Rosenberg and Peter Blum have been appointed co-presidents and chief executives of Ladenburg Thalmann & Co, and Steven Kaplan has been named head of capital markets.

Mark Zeitchick, who previously served as president and chief executive at Ladenburg Thalmann & Co, will continue to serve as executive vice president at Ladenburg and as a member of the firm’s board of directors, positions he’s held since 1999.

"David, Peter and Steven are highly experienced and dedicated individuals who have been instrumental in developing Ladenburg's capital markets business, particularly our yield-oriented equity group. Our broker-dealer business will benefit from their leadership in these new roles,” said Zeitchick.

Prior to the changes, Malamed was a co-chief operating officer at the firm. During his time with the company he has helped oversee the growth of the firm’s investment banking and asset management businesses and has been key to the integration of broker-dealer acquisitions made by Ladenburg, the firm said in its statement.

Rosenberg also previously served as co-chief operating officer at Ladenburg Thalmann & Co, and served as chief executive and co-founder of BroadWall Capital prior to joining at Ladenburg.

Blum previously served as head of capital markets at Ladenburg Thalmann & Co and has also been head of investment banking at Ladenburg. Kaplan, meanwhile, is a former managing director in Ladenburg’s investment banking group.

Ladenburg Thalmann Financial Services operates in the fields of brokerage and advisory services, investment banking, equity research, institutional sales and trading, and asset management through its subsidiaries. It has approximately $70 billion in client assets and 2,700 financial advisors.
