She began teaching at Herkimer in 1988 and in the fall of 1998, she began teaching online for the college. Over the years, she has prepared 12 different courses for the college.

These discussions have often enabled the students to expand on topic exploration with more time and detail that the traditional classroom timeline could not allow.
