Grace was new to White River Valley Middle School in the 2022-2023 school year, but has worked with students in both middle and high school for the past 15 years, mainly in mathematics. She understands that many students develop a math phobia and is eager to help them work through this and gain confidence in their math skills. When not working as an interventionist, Grace is a potter and an amateur gardener. A recent summer adventure was visiting relatives outside Glacier National Park in Montana where she got to walk over the continental divide and see glaciers and marmots but no mountain goats or grizzlies. Grace lives in Bethel with her husband, son, dog, cat, and (currently) 7 chickens.
