More than a year after she completed the sale of the Institute of Private Investors (IPI) to Campden Media, Charlotte Beyer, a founder of IPI, has stepped down as CEO.

Beginning earlier this year, Beyer transferred her duties to IPI Executive Director Mindy Rosenthal, who is also managing director of Campden Wealth U.S., and to Dominic Samuelson, managing director of Campden Wealth.

"Letting go is never easy, and at the same time, I can see clearly that the next generation at IPI is ready and eager to assume the leadership," Beyer, who has been with IPI for 20 years, said in a prepared statement. Her resignation took effect Monday, August 20.

Beyer will serve as an advisor to the private wealth management programs that IPI runs with The Wharton School of the University of Pennsylvania and with Singapore Management University. Beyer also will be active in The Wharton IPI Private Wealth Network that was announced earlier this month.

She also is on the board of the Museum of American Finance and has created a private foundation. IPI provides educational and networking resources for ultra-high-net-worth investors. It offers educational and online networking to 1,100 investors from offices in New York City and San Francisco.

Campden Wealth, a subsidiary of Campden Media, provides education, news, research and conferences to the principals of ultra-high-net-worth financial and business-owning families globally.

The next phase of IPI's growth plan has been launched with the establishment of regional membership communities in Europe, the Middle East and Asia.
