Tekatsi:tsia’kwa Katsi Cook (Wolf Clan member of the Akwesasne Mohawk Nation), an Onkwehonweh traditional midwife, lifelong advocate of Indigenous midwifery and Native women’s health throughout the life-cycle (drawing from the longhouse traditionalist teaching that “woman Is the first environment”), is Executive Director of the Spirit Aligned Leadership Program. Her work over many decades has spanned a range of worlds and disciplines at the intersections of environmental reproductive health and justice, research, and policy. Katsi’s groundbreaking environmental research of Mohawk mother’s milk revealed the intergenerational impact of industrial chemicals on the health of her community, and she is a major figure in a movement of matrilineal awareness and “rematriation” in Native life.
