We’re committed to working for you, with you.
Common Interests was formed in 1994 after Bob Goellner got his big office in the corner as manager of a mid-sized insurance and stock brokerage branch. Succeeding by every available metric, he realized he wanted to move beyond the way the industry worked at the time, and resolved to strike off on his own.
The name comes from the way we choose to work with clients. When we work together, our interests become common. There are no winners, no losers, and nobody comes out on top. Problem solving comes first, and any products we discuss are only presented as tools to solve whatever issue brought you into our office.
Our story concludes with our logo: the world in an eye. This is the driver, the mechanism that meets the standards of social responsibility while looking ahead to a bright future; for ourselves and the global village in which we live.
Our Practice
Social responsibility lies at the core of our Practice. At Common Interests, we start our investment process in the same place as the rest of the industry: with the fundamentals of the companies we invest in. We look at balance sheets, price-earnings ratios, and the rest of each company’s financial statistics. The difference comes when we overlay our values system on the investments we choose.
We view long term investing as casting a vote. For the core of our portfolios, we refuse to cast that vote for companies that are messing up our planet, treating their people in ways we wouldn’t want to be treated, or “cooking the books.” Investments are filtered through Environmental, Social and Governance (ESG) screens to ensure we’re having the most impact.
The team at Common Interests is proud to be active citizens of our community and the world. We are an award-winning certified B-Corporation and signatories of the UN’s Principles of Responsible Investment.

Common Interests is a Certified B Corp!
Common Interests became a Certified B Corporation in 2014 to “put our money where our mouth is” by having the independent organization B Lab audit our business practices. We believe that our investments should practice transparency by disclosing their Environmental, Social, and Governance (ESG) standards and performance, and we hold ourselves to the same standard. It’s important to us that our clients see and understand our business practices as well as our commitment to sustainability. As part of this, we commit to having at least 75% of our clients be local and independent. And we only surround ourselves with like-minded individuals and companies—those that believe in giving back and making the world a better place.
What is a B Corp?
B Corp is to business what Fair Trade certification is to coffee or USDA Organic certification is to milk.
B Corps are for-profit companies certified by the nonprofit B Lab to meet rigorous standards of social and environmental performance, accountability, and transparency.
Alongside Common Interests, there is a growing community of more than 2,400 Certified B Corps from 50+ countries and over 130 industries working together toward 1 unifying goal: to redefine success in business. Read more at bcorporation.net
We’ve been voted “Best for the World” – Four Years in a row!
For the Fourth year in a row, Common Interests has been honored in the Best for Customers list, which includes businesses that earned a Customer score in the top 10 percent of more than 2,700 Certified B Corporations on the B Impact Assessment.
The Customer portion of the B Impact Assessment measures the impact a company has on its customers by focusing on whether a company sells products or services that promote public benefit and if those products/services are targeted toward serving underserved populations. The section also measures whether a company’s product or service is designed to solve a social or environmental issue (improving health, preserving environment, creating economic opportunity for individuals or communities, promoting the arts/sciences, or increasing the flow of capital to purpose-driven enterprises). Honorees scoring in the top 10 percent set a gold standard for the high impact that business as a force for good can make on consumers around the world.
