Leslie has a bachelor’s degree in biology from Macalester College, and a master’s degree in horticulture with a minor in water resources science from the University of Minnesota, and spends most of her time (when not chauffeuring the kids) either reading a good book, spending time outdoors, or dreaming of mountains in Montana.
