Campden Wealth has promoted Mindy Rosenthal to president of its Institute for Private Investors US subsidiary and appointed David Berger as chief executive for the Americas.

Rosenthal has served as executive director of IPI, a membership organization for wealthy individuals, since Campden Wealth acquired it in 2011. Rosenthal, who joined the firm back in 2007, will now concentrate on overseeing services and content for IPI member families, the firm said.

Meanwhile, Berger will be responsible for strategic planning, business development, operations and new technology initiatives in North and South America.

Berger joins Campden Wealth from Asia Executive Solutions, a Hong Kong-based consultancy he founded which advised professional and financial services clients entering Asian markets.

Both executives are based in New York and report to Dominic Samuelson, CEO of Campden Wealth.

“These appointments mark the next chapter in Campden Wealth's growth. With Mindy continuing and expanding her leadership of IPI, and David coming on board, we see exciting opportunities for our business in the US, and overall in North and South America,” Samuelson said.

The firm has offices in London, New York and Singapore, while the Institute for Private Investors has offices in New York and San Francisco, CA.
