Hospitality has always been in his family. The ambition is the same as it ever was.

Trevor's father, Anthony Cornwell, was creative director at Needham & Grohmann in the 1960s — overseeing the branding for Laurance Rockefeller's RockResorts: Mauna Kea, Caneel Bay, Little Dix Bay. The original eco-luxury properties, where design and landscape were inseparable from service.

Six decades later, Trevor founded Guesthouse to build what his father's era only glimpsed: a scalable hospitality model where a central Hall — with a commercial kitchen, professional staff, and hotel-grade infrastructure — serves a campus of premium homes within a 15-minute radius. The hub unlocks what vacation rentals cannot: consistent, elevated service delivered at group scale.

The model is designed to travel. Hub-and-spoke replicates across supply-constrained lifestyle markets — Truckee, Palm Springs, and beyond. One operating system. Many campuses. 100 by 2035.
