MEET HOLLY O’BRIEN

FOUNDER + PRINCIPAL DESIGNER

Holly’s relationship with interior design developed gradually, shaped by time spent around residential construction and an understanding of how decisions made early on influence everything that follows. As the daughter of a seasoned general contractor, this meant seeing the parts of a project many homeowners never do, including the sequencing behind each decision, the compromises that come with execution, and the discipline required to produce work that holds up over time.

That exposure shaped how she approaches interiors today. A home can be well built and still feel unsettled in subtle but persistent ways. Rooms that look finished but do not support daily routines. Layouts that meet technical requirements yet never feel quite right. Interior design, at its best, brings those loose ends into alignment, clarifying how a home is meant to be used and how it should feel to move through.

Opal Avenue Interior Design was founded on that belief.

Holly does not equate luxury with abundance or ornament. She associates it with judgment. Knowing where to invest, where to pull back, and when restraint produces a stronger result. Her work prioritizes proportion, material honesty, and decisions that strengthen the whole rather than compete for attention. The result is a home that feels cohesive, comfortable, and assured.

The studio’s work is grounded in classical design principles, filtered through a modern, editorial point of view. Holly is drawn to spaces with tension and depth, where architectural elements are allowed to carry weight, materials are chosen for how they wear over time, and contrast is introduced with purpose. She is known for helping clients move past safe defaults, guiding them toward choices that give a home character rather than sameness.

Holly leads projects with clarity and a steady hand. She listens carefully, edits decisively, and manages the many moving parts so clients do not have to. Her role is not to offer endless options, but to make sense of complexity, translating ideas into a coherent direction and ensuring the process unfolds in the right order, at the right pace.

Holly is a graduate of the New York Institute of Art and Design and holds the Residential Interior Design Qualifying Certification through the Designer Society of America. Originally from the East Coast, she is now based in Arizona, where her work is influenced by travel, fashion, and an appreciation for spaces designed to be lived in and enjoyed.
