Interior Design

Pearson Design Interiors fosters harmonious and balanced relationships between architectural interior and exterior spaces. Working in concert with our Architectural Group, we create cohesive environments that reverberate our practiced attention to every design detail, accompanied with an organic, handcrafted sensibility. Our surroundings are intrinsically enhanced through lighting, fixtures, artwork, fabrics, antiques and furniture. Pearson Design Interiors offers a continuum of services from Conceptual Design to Procurement to Installation. Exceptional interior design should honor the architectural structure of a place, instead of distract. At Pearson Design Interiors, we celebrate the resonance and character of the space that surrounds us.


Our Team


Oshi Gardarian, Interior Designer

Born and raised in Vail, Colorado, Oshi started skiing at the age of 3. As a teen, she discovered her passion for designing creative interiors others could relate to and enjoy. After earning a BS in Interior Design from Colorado State University she began her dynamic career in high-end residential design, creating, managing, procuring, and installing projects throughout the U.S. At PDG she delights in shaping custom spaces to suit the singular style of each client. She especially enjoys translating her lifelong love of the outdoors into biophilic design, in which various facets of the natural world are beautifully integrated into homes.


Leisa Kolstad, Interior Designer

Leisa’s passion for art and design was inspired in part by her grandmother, who taught her to paint and sketch. After graduating from The Art Institute in Seattle in 2010, Leisa lent her talent to projects spanning from the Bahamas and Mexico to California and Montana. At PDG, she loves exploring the creative maze that is her mind. Learning about different eras of art and design and interlacing them allows her to create spaces that feel fresh. Her passion persists outside of work; she’s always on the lookout for unique pieces to invest in.


Chelsie Bosshart, Interiors Purchasing Manager

Chelsie manages all the purchasing for our interior projects and plays a key role in ensuring our clients’ indoor environments are complete and stunning. Detail oriented, she thrives on seeing a project through to its completion. She attributes her strong work ethic to having been born and raised in Butte, Montana. Prior to joining PDG, Chelsie earned a degree from MSU, where she studied Marketing, Management, and Entrepreneurship, and worked in San Francisco as a buyer for Pottery Barn. She delights in the Montana summer season and in spending time with her husband and baby girl.
