Since then, she has advanced both the quality and accessibility of hospice care and leadership development for struggling organizations. In addition to her work with the foundation, Cassin continues to lead the National Hospice Work Group (NHWG) 17 years after becoming one of its founding members. A coalition of executives from some of the nation's largest and most innovative hospices, NHWG works to increase access to hospice and palliative care.
