Some ad agencies crank out one look and one feel. A signature style. At O’Brien, we do one thing consistently — it’s called finding just the right business solution for each challenge. “Problem-solving” crafted for each client’s unique situation isn’t your everyday agency service, but here, we embrace it head on.

Who we are

We're hoping you’re here because you Googled: "nice people + advertising agency + brilliance + plays well with others." Or perhaps “Emotionally-compelling + memorable + likeable + smart + breakthrough + award-winning advertising that gets results.” Heck, we'd be okay if you got here by searching: "six-pack abs". But last we checked that wasn’t the case. This is who we really are— in all our real-life glory.


Healthcare advertising solutions that are just what the doctor ordered. You could say we’re healthcare specialists. We started winning awards for healthcare advertising before healthcare advertising had award shows. We know what’s important to a hospital and how to make it digestible to the consumer in an emotional, compelling way. We understand the complexities and nuances of healthcare systems, hospitals, boards, physicians and the changing face of healthcare. We’ve worked on every service line from obstetrics to geriatrics. Or neurosurgery to podiatry care.

We’ve rolled out the red carpet for many hotels, spas and resorts over the years. Rooms were filled with occupancy rates much higher than expected and we've won our share of creative awards in the process. Our Creative Director has had a dual career as a travel writer, which includes reviews of many of the world’s top destination hotels. So whether you’re looking to increase your ADR, grow off-season occupancy, build F & B revenue or expand meeting and wedding business, we’d love to make you a reservation.

The word ‘client’ only tells part of our story. These are our colleagues. Partners. Friends. Most of which are longstanding, rewarding relationships that far surpass the average client/agency contract period. And we’re especially proud of the results we’ve brought them.
