Brown Brothers Harriman & Co. has named Owen Weihman a Managing Director in its New York-based Corporate Advisory and Banking division, hiring him away from Brown Gibbons Lang & Co., where he held the same title and co-led the firm's Digital Infrastructure practice.

The appointment signals BBH's intent to deepen its advisory relationships with owners of privately held businesses. Weihman's remit covers the full sequence of decisions those owners face: growth planning, capital planning, succession, mergers and acquisitions, and liquidity events.

Lewis Hart, Partner and Head of Corporate Advisory and Banking at BBH, said the appointment would enhance the firm's ability to guide owners through some of their most important decisions.

What does the hire bring to BBH?

Weihman arrives with a sector portfolio that maps closely to deal flow in communications and infrastructure. At Brown Gibbons Lang & Co., he co-led the development of the firm's Digital Infrastructure practice, expanding its advisory activities in communications networks and related infrastructure businesses.

His industry experience spans:

• Digital infrastructure
• Telecommunications and communications networks
• Transportation
• Energy
• Paper and packaging
• Payments
• Media
• Chemicals

That breadth matters for BBH's stated goal of expanding advisory work with privately held companies evaluating strategic alternatives and long-term ownership plans — a client base whose needs cut across sectors rather than concentrate in one.

Before his time at Brown Gibbons Lang, Weihman held investment banking positions at Rubicon Capital Advisors and Bank of America Merrill Lynch. Across those roles he built experience in corporate transactions, financing and strategic advisory services.

Why is this appointment significant for BBH?

The Corporate Advisory and Banking division targets a specific market: owners of privately held businesses weighing whether to grow, sell, transfer ownership or raise capital. Those decisions often carry personal as well as financial weight, spanning families and succession as much as balance sheets.

BBH, a privately held financial services firm, has positioned this division as a channel for long-term advisory relationships rather than transaction-by-transaction mandates. Adding a managing director with deal experience across digital infrastructure and adjacent sectors extends the bench in areas where private ownership is common and infrastructure investment is active.

On joining the firm, Weihman said he looked forward to helping business owners evaluate strategic opportunities and make critical decisions for their companies, families and futures.

Who is Owen Weihman?

Weihman's career track runs through three investment banking houses before BBH:

• Investment banking roles, Bank of America Merrill Lynch — earlier positions across transaction and advisory work.

He holds a Bachelor of Arts degree from Williams College and an MBA from the University of Virginia's Darden School of Business.

He will be based in New York.

What happens next?

The hire is effective with the announcement, and Weihman begins building relationships with private business owners from BBH's New York base.
