About Us

We serve a select group of endowments, foundations and non-profits managing over $10.4 billion in investment assets (as of 10/1/2017) across 13 clients. We serve clients on a discretionary or non-discretionary basis. We invest globally across traditional and alternative asset classes. We advise our clients on all aspects of their investment portfolios, so working with us is like having your own CIO down the hall.

Our global experience, network, and perspective as investors lead us to the best investment opportunities for each client.

CornerStone is 100% owned by its partners, each of whom is fully active in the firm. Being independent frees us to think and act only in the best interests of our clients. Under no pressure to grow, we can carefully weigh each potential new client opportunity. We have designed our business model to ensure that our working relationship with each client is a close one. Our clients always work directly with the principals of CornerStone. At CornerStone, we manage portfolios, not large groups of people. We focus on building customized portfolios that deliver results consistent with each client’s investment objectives. In our experience, this focus leads to better results.

Our clients are involved in healthcare, education, and the environment. We find it rewarding to work with people whom we respect and organizations that we admire.
