NEW YORK: Rubenstein Public Relations has won the accounts of investment management firm Calamos Investments and investigations firm Nardello & Co.
Reps from all three companies were not available for comment about what Rubenstein will be handling.
In March, Calamos, which has $20.1 billion in assets under its management, appointed John Koudounis as CEO. He is the former CEO of Mizuho Americas, a financial services company. Koudounis created his share of media buzz as the youngest CEO on Wall Street when he was appointed the position in 2010.
Calamos also recently appointed a new CFO, Thomas Herman of Harris Associates, an investment management firm.
Calamos is headquartered in metropolitan Chicago, with offices in New York and London. The company has more than 350 employees, 70 of which are investment professionals.
Nardello is led by CEO and founder Dan Nardello, a former U.S. federal prosecutor, who worked as an assistant U.S. attorney under then-Attorney Rudolph Giuliani. Its clients include Fortune 500 companies and governments.
Nardello has been expanding into the Asia-Pacific region, with the June 1 opening of its Tokyo office and appointment of Toshinari Asano, as MD and Japan practice head. Toshinari worked as a representative director for Blackpeak, an investigative research and risk advisory firm.
In April, Nardello appointed FTI Consulting alum Amie Chang as Hong Kong office head.
