Karen R. Edsell

M44's 1st Board Secretary - Emeritus

Karen R. Edsell, M44’s 1st Board Secretary, died from Metastatic Breast Cancer on July 11, 2024. Karen was more than a Board member; she was our CEO’s Cancer BFF and True North, offering unwavering support, encouragement, and valued wisdom. Mary insists that Karen’s mere presence—through the relatively simple act of just “being there”—transformed M44 from Mary’s tentative, early ideas into the committed organization we are today. M44 exists BECAUSE of Karen. As such, she will remain positioned right next to Mary on this Board list… in perpetuity. (more…)
