Built for Those Who
Build Across Borders

Globally distributed founders and executives trust Grey River to hold the whole board: international tax, residency, structures, and capital.

The Practice

One continuous view of a life
held across jurisdictions.

When you move offshore, your former advisors step back; most cannot service non-residents. Grey River closes that gap: the tax and residency position, the holding structures, and the capital itself, held in a single disciplined view.

Illustrative: the consolidated annual view maintained under a Cross-Border Wealth Oversight engagement. Clients hold and direct their own accounts.

Clients engage
Grey River for
  • Exit & Departure Tax
  • Treaty Positioning
  • Residency Programs
  • Holding Structures
  • Asset Protection
  • Net-Worth Consolidation
  • Quarterly Oversight

“I help clients consider better personal residency options and restructure their businesses, while maintaining global regulatory compliance and preserving long-term wealth.”

Private-client discretion,
institutional discipline

Engagements are governed by strict confidentiality. Clients hold and direct their own accounts. Grey River provides the analysis, the framework, and the discipline, not discretionary management.
