Former executives of wealth management business Affiliated Managers Group have launched Wealth Partners Capital Group, a new firm focused on acquiring smaller RIAs, according to a press release from Wealth Partners.

Headed by John Copeland, Rich Gill and Sean Bresnan, Wealth Partners took minority stakes in platform firms Forbes Family Trust, MAI Capital Management and EP Wealth Advisors, which together oversee $11 billion in client assets, according to the press release.

Wealth Partners will assist the three firms in acquiring RIAs looking for partners and operational platforms, the company says. Partners in each of the three platform firms, meanwhile, will continue to run day-to-day operations and control the majority of the equity, Wealth Partners says in the press release. The company didn’t disclose the terms of the deal.

The company chose the three firms based in part on the strength of their regional brands. EP Wealth Advisors, which managed $2.9 billion as of the end of June, is a fee-only RIA and financial planning practice based in Los Angeles with offices in California, Washington and Colorado. Forbes Family Trust, which manages $4 billion, serves high net worth and ultra high net worth clients from offices in New York and Philadelphia. MAI Capital Management, meanwhile, manages $4 billion out of offices in Ohio, Florida, New Hampshire and California.
