"If I am selected for this position, I promise to work toward the best possible educational decisions, combined with responsible financial considerations for the students, staff and residents of Bloomingdale," Gurbisz wrote in her letter of interest submitted to the board before her appointment.
In particular, Gurbisz wrote that she is interested in assisting with preparation of the 2012 Budget, teacher negotiations and professional development.
Gurbisz has a bachelor's degree in accounting and over 26 years of experience in the accounting and financial field. She currently works as an accounting supervisor for Greenwood Abatement.
Gurbisz's appointment is valid through the school board election in April.
