Sierra Smith

Design Assistant

After attending University of West Georgia, Sierra realized her true passion and enrolled at Chattahoochee Technical College to pursue her dream of becoming an interior designer. As a part of her course requirements, she joined Modify as an intern, and the rest is history! Her love for computer aided design (CAD) and space planning, with an emphasis on kitchen and bath made her a clear fit for our business. Not only did she love home furnishings, lighting, textiles and all things beautiful – she also loved the technical elements of the work.
Her personal design style is a mixture of organic, modern farmhouse, and coastal. Bottom line: Sierra likes style, but wants it comfortable. You can see this in her personality too – she is relaxed and comfortable.

Curiosity, passion, collaboration, and fun. Curiosity drives our creativity. Passion keeps us energized. Collaboration builds effectiveness. Fun gives us joy.


That every structure we encounter – whether that be a home or commercial space – is waiting to be redeemed. Spaces have beauty that can be carved out of wood, steel and drywall. And spaces are a place where people connect and form community. Connection and community are important, because ultimately every soul longs for redemption too.
