About Horizon Holding Corporation

Horizon Holding Corporation is a discreet family office in Vienna, Virginia, created to steward fine art, domains, and digital projects across a single family ecosystem.

Origin & Scale

Horizon was formed to connect the practical operations of the holding company with the artistic legacy of McMahon Fine Art and McMahon Studio. We run intentionally lean with only a couple of full-time team members and a small network of part-time collaborators.

Philosophy

Our approach prioritizes long-term preservation, careful risk management, and quiet execution behind the scenes. Every decision favors continuity, documentation, and measured progress rather than speed for its own sake.

Connections

The holding company supports the creative work of McMahon Fine Art and McMahon Studio while managing related digital archives and domain infrastructure. This alignment keeps the family’s artistic and technical assets organized, protected, and ready for the next generation.
