Serving our clients and community for thirty years

We invest with intention to serve a greater good.

Arnerich Massena was founded in 1991 in Portland, Oregon. Since then, our independent firm has worked to be a model of corporate citizenship, from our unparalleled client service to our uncommon investment approach to our commitment to our community. Focused on client service and intentional investing, we create portfolios that reflect the top-tier research and collaborative expertise we have cultivated over three decades working with private clients, foundations, and endowments.

Arnerich Massena has been a pioneer in the investment industry, bringing innovation and a forward-looking approach to investment research and portfolio construction. Since 1991, Arnerich Massena has researched, built, and successfully implemented alternative investment strategies, building specialized expertise in private markets investing. In 1995, we began positioning portfolios to capture the global market opportunity. Arnerich Massena began researching sustainable investing in 2007 and was a frontrunner in establishing a multi-asset class funding strategy focused on impact investment themes, and continues to be a thought leader in this space, helping clients to align their investments with their values. Also an early adopter of frontier market investing, we continue to bring vision and innovation to our clients as we move forward in a constantly evolving investment landscape.

In 2017, Arnerich Massena transitioned to a 100% employee-owned structure via a management buyout, and a group of senior employees share equity ownership of the firm. In 2018, Arnerich Massena was listed among the top 20 largest women-owned firms by The Portland Business Journal, and it is a source of pride that the firm's ownership, leadership, and advisory team continue to be evenly balanced between men and women. Our structure carries forth our legacy and ensures that the firm will continue to serve clients with independence, integrity, and innovation.

Community service and support are fundamental to our philosophy, vision, and culture. Arnerich Massena is dedicated to giving back in many ways, including serving with our time, donating dollars, and offering our collaboration and support. We are proud to be part of helping our community thrive and investing in the next generation.
