Services

See Opportunity in the Ordinary.

We serve clients in a variety of market sectors including office, multi-family, retail, mixed-use, industrial, assisted living, healthcare, civic, and interiors.

When we say "we are always curious," it means we are self-starters, continuous learners, and question-askers pushing to get better and looking for opportunities in the ordinary. This is rooted in a belief system built upon the shoulders of our founder, Jack O'Brien.

See Opportunity in the Ordinary

Overview

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.

Approach

We have a long-standing reputation for innovative design solutions that spans more than 4,500 projects nationwide in a variety of market segments and architecture disciplines, including: Commercial Office, Industrial, Master Planning, Multi-Family, Assisted Living, Healthcare, Retail, Mixed-Use and Corporate Interiors.

When we say "we are always curious," it means we are self-starters, continuous learners, and question-askers pushing to get better and looking for opportunities in the ordinary. This is rooted in a belief system built upon the legacy of our founder, Jack O'Brien, who set the pattern of creative, friendly, professional, and open experiences with our clients and team members.

You'll Actually Enjoy the Process.
Our work is challenging, but we push ourselves to be excellent at it and have a good time doing it. We deliver speed with consistency, no matter where you grow. We create an experience with you that is creative, friendly, professional, and open. We treat design as a journey with you—not an impersonal process and result to be delivered. You’ll actually enjoy the journey!
