Our Board of Trustees

Leading with Expertise. Driven by Personal Stakes.

The IWMF Board of Trustees is not your typical nonprofit board. These are accomplished leaders—executives, clinicians, entrepreneurs, and scientists—who bring world-class expertise to our mission. But what truly sets them apart is this: every single trustee either lives with Waldenstrom macroglobulinemia (WM) or stands beside someone who does. They know what it means to wait for test results. To ask hard questions. To hope for a better treatment—or a cure.

Their commitment is total. They donate their time, their professional skillsets, and their financial resources. They show up—in meetings, in support groups, in research planning sessions—not just as board members, but as members of the WM community. That’s why their leadership matters. That’s why they push for results. And that’s why you can trust that IWMF is all-in, from the inside out.
