Board of Directors

Sharon Roberts

Sharon began her teaching career at Del Valle Junior High School in a self-contained special education classroom. Sharon also taught English and Language Arts and became an Instructor for the New Jersey Writing Project.

In 1998, Sharon started a dyslexia program at her junior high and developed a reading lab program for struggling students.  Despite her varied experiences in education, learning how to teach reading to students with dyslexia was a profound turning point in her career and life.  As a result of the program and the students’ success, Sharon took on the newly created position of Secondary Dyslexia/Reading Coordinator.

For over a decade, Sharon served as the Dyslexia, 504, and General Ed Homebound Coordinator. During this time, she became a Master Reading Teacher, received training in several dyslexia programs, and continued to develop the district’s dyslexia program. Sharon returned to the classroom for the last four years of her career to reconnect with students, administer assessments, and work to implement the latest scientific reading research in the K-12 classroom.

Sharon has actively served on numerous boards, including previous service on the board of IDA Austin. She hopes to build on the work that has been done, keep the Board challenged, and honor IDA’s traditions.

In her free time, Sharon loves baking, scrapbooking, traveling, and all things grandchildren, including learning to fish and pitch baseball. She also enjoys making an annual beach trip every summer with the teachers she hired and trained during the course of her career.
