Tierney Conner Design Studio

Who We Are


Within minutes of meeting, Anne Tierney and Erin Conner realized that their lives had nearly crossed paths many times. They had worked at the same company for a year, lived only blocks apart with mutual childhood friends, and had attended the same architecture program in Denmark, years earlier. An inevitable friendship evolved over their love of plants, modern architecture, California living and earl grey. A decade later, with an empty garage beckoning them, and two babies on the way, their Mom and Mom shop was born.

What We Do


We are a multi-disciplinary firm weaving together the fields of architecture, landscape and interiors. Founding partners Anne and Erin both hold graduate degrees in architecture and also have formal education in landscape architecture.
