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.
