Flume joins Angeles Family Office as Angeles Investments’ institutional and private wealth businesses collectively serve clients in Texas with approximately $13 billion in client assets
SANTA MONICA, Calif.–(BUSINESS WIRE)–Angeles Family Office (“AFO”), the family office affiliate of Angeles Wealth Management (“Angeles Wealth”) designed to serve families with complex, large-scale wealth, today announced the appointment of Kate Flume as Senior Managing Director. Based in Dallas, Flume joins AFO as the firm continues to expand its team of specialists dedicated to serving families of exceptional means. Her appointment coincides with Angeles Investments’ continued expansion in Texas, where its institutional and private wealth businesses now advise approximately $13 billion in assets.
Flume will focus on substantial families requiring institutional investment rigor who prefer not to build or manage a full-scale single-family office. She will serve as a strategic advisor and central point of contact to families, integrating investment strategy, liquidity planning, governance, succession planning, philanthropy, executive reporting and next-generation preparation into a unified capital framework. By coordinating across internal specialists and external legal, tax, fiduciary and investment partners, Flume will work with each family to deliver cohesive oversight, streamlined execution and tailored guidance aligned with their goals and lifestyle.
“Families today are managing increasingly complex wealth structures and are seeking a partner who can integrate solutions and simplify the process. I see my role as an ‘expert generalist’—someone who can bring the right specialists together, provide clear oversight and help families navigate any financial challenge with confidence,” said Flume. “What first drew me to AFO was its distinctive model: a boutique, deeply personal experience for every family, backed by the strength and 20-year track record of Angeles Investment Advisors. That combination is rare, and it allows us to deliver both intimacy and rigor in service of each family’s long-term goals.”
Following its acquisition of XO Capital in 2025, Angeles Wealth established AFO in January 2026 to serve families across a broad spectrum of needs — from discretionary portfolio and investment management, including building durable private equity portfolios, to full-service family office integration and execution — combining wealth advisory and operational support with the institutional-quality investment capabilities of Angeles Investment Advisors (“AIA”) for affluent families. Unlike many firms that have recently adopted the “family office” label, AFO was built on decades of institutional investment experience and single-family office roots, providing families access to resources typically reserved for billionaires and institutional investors such as endowments and foundations. Since launch, the firm has been focused on investing in talent and regional growth to address the evolving needs of ultra-high-net-worth clients, particularly in markets like Dallas, which have seen increased demand for sophisticated yet accessible family office solutions.
“Texas represents a dynamic and growing community of complex, entrepreneurial families,” said Jonathan Foster, President and CEO of Angeles Wealth. “Kate’s extensive experience advising high-net-worth families, combined with her ability to serve as a trusted integrator for family office needs, strengthens our presence in Texas and gives us a leader with a unique skill set to continue our growth in this market. She exemplifies the caliber of professionals we are attracting to serve families across the country.”
Flume is a seasoned leader who specializes in advising first-and second-generation principals on long-term capital stewardship. Prior to joining AFO, she was a senior managing director at CH Investment Partners, where she co-led the client advisory business. She began her investment career at Goldman Sachs, building and advising a private wealth practice. Her distinctive background reflects a deep ethic of care and holistic problem-solving, having started her career as a nurse at Johns Hopkins Hospital before earning her MBA in finance and strategy from Southern Methodist University.
“Families in the $100 million to billion-dollar cohort are looking for a single point of accountability. They’re increasingly reassessing whether maintaining a fully built-out single-family office is efficient or necessary,”” said Adam Stern, CEO of Angeles Family Office. “Kate’s ability to serve as a financial quarterback—coordinating advisors and specialists, streamlining structures and reducing unnecessary complexity—directly advances our vision of delivering an efficient single-family office experience that introduces institutional capability without institutional overhead. We’re confident she will add notable and immediate value.”
Flume’s arrival at AFO marks the second significant hire by Angeles Wealth and its affiliates in the past three months, following the appointment of Jonah Cave as the firm’s first Chief Growth Officer last November. With both Flume and Cave based in Dallas — and a rapidly growing concentration of clients and talent in Texas —Angeles Wealth and AFO plans to open a Dallas office, further solidifying its long-term commitment to the region.
