Diamond Wealth founder brings more than two decades of family-office experience as Twin Oak deepens its work with leading single- and multi-family offices

WELLESLEY, Mass., Sept. 9, 2026 /PRNewswire/ -- Twin Oak ETF Company today announced that Ronald Diamond, founder and chairman of Diamond Wealth, has been named Chair of the firm's Family Office Advisory Board.

The appointment brings one of the family-office community's most experienced investors and network builders closer to Twin Oak as the firm expands its work with single- and multi-family offices and the wealth-management professionals who serve them.

"Ron understands how family offices actually make investment decisions, starting with what the capital needs to accomplish and looking across the portfolio rather than at any one product in isolation," said Zach Wainwright, co-founder and chief executive officer of Twin Oak. "That perspective is very much aligned with how we are building Twin Oak, and having Ron close to the firm will help us stay connected to how the needs of family offices are evolving."

Diamond has spent more than two decades working with family offices and private investors. He is the founder and chairman of Diamond Wealth, a syndicate of more than 100 family offices ranging from $250 million to $30 billion in size that invests across private equity, real estate, venture capital, credit and special situations. He also founded Family Office World Media, helped build the family office program at TIGER 21, where he chaired a national Family Office Group, and serves on the Advisory Board of the University of Chicago Booth School of Business Family Office Initiative. He has also taught at Oxford, Stanford and Harvard.

As Chair of the Family Office Advisory Board, Diamond will advise Twin Oak as it works with leading single- and multi-family offices, helping the firm stay close to the issues shaping those investors and deepen its relationships across the family-office community.

"Family offices tend to evaluate investments differently because they have to think about the entire portfolio — strategy, structure, liquidity, taxes and time horizon all matter," Diamond said. "Twin Oak understands that. The team is building from the investor's objective outward, and I'm looking forward to working with Zach and the team as the firm continues to grow."
