The Board Spiritual

The Board Spiritual was implemented in the mid 1990s. It was done to honor and celebrate the lives of the many COTT Directors who have passed into the spirit world as a result of the AIDS/blood epidemic. What the men and women of COTT call, the hemophilia holocaust. No disrespect meant to holocausts of the past, however, for us at COTT, the preventable deaths of three generations of persons with hemophilia in a decade, over 50 percent of the entire American hemophilia community, can only be termed a holocaust. The community has been physically, emotionally and economically devastated by this preventable nightmare that is the result of corporate avarice and indifference, government inaction and in general, silence from the medical community. The Board Spiritual is part of our commitment to never forgot our lost loved ones and to always celebrate their lives and our own, always remembering for COTT, Action=Life. More...
