Michael A. Manneh

Founders, executives, families, and businesses rarely experience their financial lives in clearly defined stages. Growth, liquidity, risk, and personal decisions tend to converge under pressure, precisely when coordination matters most. Yet advice is still too often fragmented across firms, teams, and specialties.
Pierre and Michael Manneh each spent decades advising clients through these moments from different vantage points. Pierre worked closely with founders, executives, and individuals as they built companies, navigated inflection points, and prepared for liquidity and transition. In parallel with that work, Michael advised many of the same types of clients, including venture-backed companies, startups, and families, helping them navigate the broader financial implications as businesses scaled and personal balance sheets became more complex.
Clients felt the friction when investments, banking, lending, and personal decisions were handled separately. The strongest outcomes came from understanding the full picture early and staying involved as decisions evolved. Bringing their experience together created one team and one place for coordinated thinking and continuity across personal, business, and investment decisions.
Today, Pierre and Michael bring that shared perspective to clients who want a more direct relationship, clearer judgment, and advice that stays aligned as circumstances change. Their work focuses on coordinated decision making across personal, business, and investment priorities, supported by the depth, stability, and global platform of Morgan Stanley. The result is a single, trusted relationship built to support complexity with clarity and endure over time.
