About SUM

Five years ago SUM was providing interim bookkeeping and data management consulting services to a number of non-profits on Nantucket. As the clients began to hire permanent bookkeeping staff, they requested that new employees be trained by SUM. To deliver a cost effective and practical solution to individual non-profits, Christina LeBlanc, founder of SUM, developed a 2-semester bookkeeping course which she taught at the Nantucket Community School. Thus far, a total of 163 students have taken the course, 61 are currently working in the field.

SUM continues to provide bookkeeping and data management consulting services to small businesses and non-profits. SUM’s bookkeeping and accounting activities are now aimed at financial restructuring: set ups and clean ups. Residual bookkeeping work is posted for placement with an independent SUM member bookkeeper.
