IESD was founded in 1984 by Ellen Bialo and Jay Sivin-Kachala. Our management philosophy is simple:


Ellen Bialo devotes her time to overall management of IESD education market research, evaluation research, and customer communication projects. She is also responsible for new business development. Bialo has served the education publishing community as chair of the Software & Information Industry Association (SIIA) Education Section board of directors, an advisor to the National Science Foundation, an industry awards judge for EdNET and the Association of Educational Publishers, and a member of the SchoolTech Exposition & Conference advisory board. In 2004 she earned the Pinnacle Mentoring Award for her work in mentoring young professionals in the education marketing field. Ms. Bialo is a founding member of the DOLS, the professional network for women in the educational publishing and technology community.

Prior to founding IESD, Bialo spent almost a decade in the classroom, teaching mathematics at both the junior and senior high school levels. She also taught courses at New York University and Teachers College in psychoeducational practice and communication and technology. She earned her graduate degree at Teachers College, Columbia University and is a certified educational psychologist.
