Gillman brings more than 20 years of experience in education as a teacher, coach, and administrator.
Gillman earned a specialist degree in educational administration from Southeast Missouri State University and a Master of Science in educational administration from Missouri Baptist University.
Superintendent Dr. Jon Isaacson said, “Jenny and Jason both bring a strong connection to Hillsboro as alumni and employees, and a clear understanding of what our students, staff, and families expect from our high school. They combine professional experience with a genuine commitment to this community and our district. Working alongside Mr. Reece, I am excited about what this new leadership team will bring as they support teachers and create a positive, focused learning environment for our students.”
