Meet Siena & Birch

Siena & Birch Interior Design is a boutique design studio creating soulful, lived-in interiors that blend vintage charm with modern ease. We help busy, design-conscious women transform their homes into beautiful, grounded spaces—with European-inspired character, intentional layering, and unpretentious luxury.

With a background in global brand creative and a heart for interiors, we bring both storytelling and structure to the design process. Our approach is rooted in slowing down, tuning in, and designing for a life well lived—at your pace, in your style, and with room to breathe.

Experienced interior designer and award-winning brand creative with a proven ability to translate brand vision into compelling, one-of-a-kind experiences and spaces.
