Our Team

Dynamic Investors with a Unique Perspective

Since 2013

At Henry James International Management we offer a range of international growth investment products, all driven by our signature “quantamental” investment strategy. 

Our team takes great pride in approaching money management from different perspectives by using our unique methodology to uncover winning equities that are perhaps a bit less obvious. While we are grounded in several decades of industry experience, our rich and diverse educational and professional backgrounds combine to give us extra impetus to illuminate points of detail that others might miss - details that may just put our investment strategies on the cutting-edge. 

We are a family-owned business based in New York City. As of December 2019, Henry James International Management advises over $745m in assets.
