Lonstein received a Masters of Architecture with distinction from Harvard University and graduated summa cum laude with a degree in architecture and a minor in art from the University of Miami’s advanced five-year specialized architecture program. The combination of his architectural training and his background in fine art continues to inform his design and his particular use of form, color and materials.

He began his career as a senior designer at Studio Sofield, where he was later elevated to design director. In this position, he served as design lead for high-end residential, retail, and hospitality projects. Over the course of 13 years at Studio Sofield, he worked on residential projects and with commercial clients ranging from Tom Ford to Boucheron.

Lonstein subsequently served as a Vice President at Tiffany & Co. where he oversaw the firm’s in-house architecture and design studio. He built a team to craft a global design concept to represent the brand but also reflect the unique locales of each store. Lonstein left Tiffany in 2015 to found his own design firm.

Lonstein’s team is comprised of experienced and creative design professionals. Their recent projects include a multi-story boutique development project in Manhattan, a privately run airport in Seattle, and private residences in Aspen and Manhattan.
