About Us

TriLibrium is a Portland, Oregon based CPA firm founded by Brian Setzler in 2008. TriLibrium was designed to break the mold of a standard Certified Public Accounting firm through innovations like our triple bottom line focus, B Corp certification, and fixed prices rather than hourly billing.

You notice the difference immediately in our name: TriLibrium is a synthesis of triple bottom line and equilibrium. “Triple bottom line” captures our commitment to the mutually supportive values—people, planet, profit—that distinguish a sustainable business. “Equilibrium” refers to our commitment to establish balance among the three bottom lines in all that we do for our clients and as a firm. (As CPAs, we appreciate things that balance!)

Inherent in our name is the promise of a different relationship than you’ve experienced with other accounting firms. Honest relationships define TriLibrium. You don’t treat your business, organization or life as a numbers game - and neither will we. In a triple-bottom-line world, numbers rarely tell the whole story or serve as an adequate guide for making decisions or measuring performance.

The human and environmental are as vital as the financial. That’s something other CPA firms don’t get. At TriLibrium, we not only get it, we demonstrate our understanding in every relationship. That’s what we mean by honest

Like our clients, we’re committed to a sustainable future and it is that kind of dedication that led TriLibrium to become the first CPA firm in the nation to become a certified B Corporation.

Today, we use our experience, skills, education and passion to serve our clients and community, advance ecological restoration and “raise the bar” for the entire accounting profession.

Our vision is to create a CPA firm that provides exceptional professional services while staying true to our mission, the tenets of sustainability and the practices of a learning organization. We’re taking numerous steps, large and small, to challenge the status quo behavior of most CPA firms, including:

  • Reducing paper consumption to a small fraction of a typical CPA practice
  • Reducing and then offsetting our greenhouse gas emissions to be a carbon neutral business
  • Recycling as much as possible in our municipality
  • Composting food waste
  • Sourcing local, recycled, energy-efficient and non-toxic products and services whenever possible
  • Actively encouraging bike riding and other low footprint forms of travel (public transit over individual car travel)
  • Reduced fees for non-profits, cooperatives, and certified B Corps.
  • Offering internships and mentoring services to college and high school students
  • Making contributions to community groups
  • …all while having a good time as we work, learn and grow
