Taking over for Louisa in 1861, May taught at the first Kindergarten founded by Elizabeth Palmer Peabody for a month before returning to her own work. Beginning in December, 1860, May was in Syracuse, New York, where she taught an early form of art therapy at Dr. Wilbur's asylum (Syracuse State School), then returned home in August, 1861[9] or 1862 to begin teaching art at the Concord school run by her father's friend Franklin Benjamin Sanborn.
