Our Approach

Sustainable, Socially Just Investment Practices

Horizons specializes in personalized service that takes into account your values, lifestyle, goals, and current financial situation. Our clients range from experienced investors to newcomers to the world of finance, those who seek to expand an existing portfolio, young people just starting out, people looking to manage a recent inheritance or plan for retirement—anyone seeking to support SRI principles as a way of aligning their finances with their values.

Unlike some large investment houses that include SRI as a smaller, less important offshoot of their overall business, Horizons maintains SRI as our exclusive focus, and pursues SRI values in our overall business practices as well as in our personal lifestyle choices.

More about us...

The concept of SRI originated in the 1980s, a time when sound investments were considered by most people to be diametrically opposed to the idea of social and environmental responsibility. When SRI investment funds first emerged, they were perceived, somewhat erroneously, as only marginally effective and something of a luxury in the world of cutthroat financial practices.

Sustainable, Responsible, Impact (SRI) investment strategies have a long history, stretching back at least to the Biblical and Quranic injunctions against financial exploitation. The modern American SRI investment industry took shape in the 1970s: with the anti-war movement early in the decade, the anti-nuclear movement after Three Mile Island, and the anti-apartheid movement, the power of investors to advocate for social justice and environmental sustainability became clear.

Our firm was founded in the fall of 1987, when Richard Barr formed an investment advisory practice with an SRI focus. To center his business on SRI strategies was an unusual idea for the time, and surviving the Crash of ’87 was no small feat. With the resources provided by his strategic partners at First Affirmative Financial Network and Cambridge Investment Research, Richard built a thriving business here in Santa Fe. In 1998, he hired Kim as an office assistant — and recognizing her gifts, particularly as she helped manage the business through the dot-com downturn of 2000-01, Richard quickly gave her more responsibility, ultimately transferring the business to her and retiring in 2007.

Kim rebranded the business as Horizons Sustainable Financial Services, helping clients through the “Great Recession” of 2008-09 and continuing to grow the business. In early 2013, Kim brought Johann into the leadership team, and together they took Horizons in a new direction. As a completely independent Registered Investment Advisory firm, Horizons is even better able to serve our clients, and other advisors, with financial planning and investment advice that remains focused on key issues in environmental sustainability and social justice — helping make the world a better place, one investment at a time.

Horizons is a proud member of US SIF: The Forum for Sustainable and Responsible Investment

More about Kim...

Kim launched her career in finance in 1998, working in the Santa Fe office of First Affirmative Financial Network, where she was mentored by strong leaders in the SRI Field.

Originally from Oregon, Kim holds a B.A. from the College of Santa Fe and an MBA in Sustainable Business from Marylhurst University in Portland. She says her graduate studies broadened her understanding of how sustainability can encompass business and government policy. “This knowledge will help me enhance the opportunities for Horizons and our clients to participate in shareholder advocacy,” she says. “So we can help clients with shares in oil companies, for example, to advocate for institutional policy changes on fracking and other environmental issues. Together, we can make a difference in the process.”
