Go from Predictable to O'MG.

Founded in 1974 by Jack O’Brien, our firm was built on the idea that people can achieve like a team and still treat each other like family.

The family has grown, but our culture remains surprisingly unchanged. That’s because we take care to work with people who share and support our values.The family-based firm has a long-standing reputation for its innovative design solutions with unique visioning and animation services.

With more than 4,500 projects completed nationwide, O’Brien Architects serves clients in a variety of market sectors including: office, multi-family, retail, mixed-use, industrial, assisted living, healthcare, civic, and interiors.

Studio Focus.

We lead, but we don’t force our ideas onto your architecture. Instead, we invite clients to participate in our creative charrettes. We check our egos at the door, and no idea is out of bounds. We avoid working strong ideas into the ground or applying a “signature style”.
