About us
JSID is a Las Vegas-based boutique studio dedicated to creating uncommon interiors for clients who seek something more personal and distinctive.
Led by three principal designers, Jennifer Catlin, Gregory Guarnieri, and Kristin Metcalf, and supported by two design assistants, a project coordinator, and a bookkeeper, our compact team delivers thoughtful attention and consistent oversight on every project.
We work on a selective number of full-service residential projects each year, traveling wherever our clients call us, whether it’s a primary residence, vacation home, yacht, or jet, across Las Vegas, Park City, Los Cabos, Manhattan, and beyond.
