The Walter Spohn Trust is led by a team of individuals committed to its mission to provide financial support for educational and research projects aimed at advancing the field of clinical anaplastology. Members of the WST Board of Directors have devoted their careers to serving patients and seek to carry on Walter Spohn's enthusiasm for sharing knowledge and experience with others. Collaboration and access to learning opportunities are essential to ensuring that anaplastologists, associated practitioners, researchers and innovators, health coverage industries, and policy makers are ALL informed about the nature of our work as clinical anaplastologists and the needs of our patients.
