Mother, teacher, coach, resident faculty - Mary Churchill wears many hats here at San Domenico!

Mary graduated from the University of Connecticut with a degree in Molecular and Cell Biology, then went on to pursue her Masters in Secondary Science Education from the same university. Her classroom expertise is in the field of biology and chemistry, having taught AP biology for most of that time. This past year, Mary taught biology and health at San Domenico and coached the Cross-Country team. Mary loves to integrate her personal passion for the outdoors with her passion for teaching and frequently designs experiential learning opportunities for her students in the wilderness. Outings that Mary has designed and facilitated have included field studies on the prairies in Montana as well as glacial studies in Juneau, Alaska. Mary and her husband Mark are both educators at San Domenico and are parents to a young son and daughter who both love exploring the natural world.
