Lisa Ljevaja
INTERIOR DESIGN PROJECT MANAGER
Lisa subconsciously knew she was destined to be a designer when she proclaimed in her sleep at 8 years old, “that’s not the way I wanted it arranged.” After stints of studying anthropology, and traveling as a beekeeper, she settled down to study Interior design at Ryerson University in Toronto. Following graduation, she had the opportunity to work on a project of the late architect Will Alsop.
Since then, Lisa’s design interests have taken her into the world of film as an art director, to NYC working in the Empire State Building on hospitality projects, managing a stained-glass studio, more hospitality work in LA and back to residential design. Through combined experiences and a multitude of interests, her design ethos has organized around storytelling to create a unique and tailored backdrop for each client and project.

Jesse Franco
INTERIOR DESIGNER
Jesse fell in love with the art of interior design and transforming spaces at a young age from watching both his mom, who had an eye for interior design, as well as his father, who is a contractor for residential properties. However, it took Jesse a few years to realize you can merge a love for art with a career.
He received his Bachelor of Science in Business Management from California State University of Northridge, following graduation he went on to work in finance for a few years. Unfulfilled, he quit his job in finance and returned to school to study Interior Design at College of the Canyons.
Since then, Jesse has worked as an Interior Designer for a luxury furniture & design company as well as independent design studios for the past three years.
He loves traveling and experiencing different parts of the world.
