Why We're

Independent and employee-owned

Our corporate structure aligns our interests with those of our stakeholders. We are accountable to our clients and to each other. As such we treat both with the utmost integrity and respect.

Commitment to a distinctive investment philosophy

By focusing on investing in the equities of companies we judge to be high quality, and by using a disciplined and repeatable process that integrates environmental, social, and governance (ESG) considerations, we believe we can produce sustainable advantages over passively managed index portfolios and other actively managed alternatives.

Leadership in ESG and impact investing

For nearly five decades, we have advanced the discipline of impact investing. We conduct ESG research in-house and use active ownership strategies to benefit companies held in client portfolios as well as society in general.

Stable and diverse team

We believe that a stable and diverse team is integral to long-term business success. Our employees’ varied backgrounds and experience, and their commitment to the firm and to each other, contribute to a creative, collaborative environment and enable more meaningful connections with our clients.
