About O'Brien

We exist to create
"O'MG Moments."

We exist to create
"O'MG Moments."

What does that mean? It means we are intentional with our client experiences from start to finish. Our work is not simply about the designs we create, it’s about all of the human interactions in between. Every encounter is an opportunity to create a memorable moment. Those moments can inspire us towards our future, and they are powerful reminders of our rich history. Since 1974, memorable stories with our clients, and with each other, have become the color, texture, and pattern that makes O’Brien a beautiful place to be.

Meet Our Team
We stay curious and driven by the desire to create memorable moments through thoughtful design. We don't believe in standard solutions or imposing our "signature style". Unlike others, O'Brien delivers bespoke architecture so it fits like a custom-tailored suit.

Big Design without Big Egos.


O’Brien Architects embodies the character of its founding President, Jack O’Brien. His emphasis on integrity, respect, and service has shaped our corporate culture. By adhering to this value system, our team has established a loyal client base and has developed professional relationships that span decades.

We Believe...

Always
Curious


Self-starters, continuous learners, and question askers push themselves and others to get better.

EQ
Elevates


Thoughtfulness is more than an approach to work. It finds creative solutions to problems and empathetic interactions with others.


Team players build meaningful relationships with co-workers and clients, value community and collaborate to elevate. That means big egos aren't allowed.

So We...


Move with speed but not in haste. Take time to look at the opportunity from different perspectives and see creative solutions that are missed by others.

Hire
Heart


Invest in people with great character who are willing to develop and grow new skills by collaborating and learning from each other.

Share
the Wins


Design in community so the credit belongs to the team as we work intentionally to elevate and celebrate the wins together.

Let's Build Your Brand.

Our clients tell us they appreciate our experience. We’ve navigated all kinds of office and interior projects, and along the way we’ve developed an effective method of getting things done.

We have embraced a collaborative design approach that is open, interactive and imaginative. To us, design is not just a process and a result. We see it as an experience where the journey we take and the relationships formed are just as important as realizing your vision.

    "Sean O’Brien and team have the creativity, alacrity and flexibility to be great design partners. They listen closely and then bring all the historical architectural smarts and a fresh eye to creating places where you’d like to be. They first think through making the public realm inviting and then enrich that with great architecture."
