We seek firms with aligned values that complement our organization where we are a stronger team together than apart

We care about the heart and soul you put into building your business, and want to know you as a leader. We value what you have built and want to accelerate your success, not burden you with bureaucracy.

Salas O’Brien connects most deeply with leaders who are not only excellent at what they do but are also invested in the future of their people. We are proactive in growing the value we provide to our clients, and the value we create for our employee-owners. We seek out industry-leading talent.

We’ve merged with over 40 partner firms in the past 10 years—from firms as small as 8 employees to teams of 300+. Each new team has sparked collaborations and created innovation for the organization. In turn, they’ve achieved the scale they need to fuel their own aspirations, providing unlimited opportunity for their team members and rising equity.

We are looking to partner with firms across North America and Europe with the following disciplines: mechanical, electrical, plumbing, structural, building envelope, sustainability, acoustics, civil, and other specialty consulting.

Bill D’OnofrioPrincipal, Salas OBrien (merged from Epsten Group)
Our merger with Salas O’Brien has provided us with the extensive resources and stability of a large firm, while allowing us to maintain localized control over operations and preserve our unique culture. It has opened doors to professional development and advanced training for our team members and provided each of our departments with a significant increase in business development opportunities, both between internal business units and with new clients.

Deb BrittonPrincipal, Salas O’Brien (merged from K2)
While working on a project for a valued client, we identified a gap in our legacy K2 team’s expertise. Typically, this would involve subcontracting third-party assistance, but instead, we tapped into our Salas O’Brien in-house talent. We collaborated with both the broader technology and acoustics team and with an architect within the firm for a code compliance review. This solution not only showcased our agility but also the potential to integrate broader company resources early in our merger process.
